该问题采用非负整数和字符串列表并返回新的数字数组。

const filterlist = [1, 2, "a", "b", 0];

function filter_list(l) {
  let arrayResult = [];
  for (const iteml of l) {
    if (parseInt(iteml)) {
      arrayResult.push(iteml);
    }
  }
  return arrayResult;
}

const res = filter_list(filterlist);

for (let i = 0; i < res.length; i++) {
  console.log(res[i]);
}

// console.log(parseInt(0));

这样做时，结果发现只解析了 1 和 2，而 0 仍然悬而未决，但是为什么当我将转换带到控制台（注释行）时，它显示这是一个数字。我知道零是一个错误值，但是我该如何绕过它呢？

有一个布局（https://www.figma.com/design/v3CYjno3KdI1XdKkhe7okC/Web-Studio-(Version-2.1)-(Copy)?node-id=3-7653&node-type=canvas&t=GIj8ZFvJBqvxqICs-0）。横幅背景图像（英雄）有问题。对于移动版本，您需要宽度为视口的 100%，高度为 400px，但是使用这些样式，图像不能完全适合，但如果设置包含，则背景图像在居中且不拉伸。

当您将鼠标悬停在链接上时，图标的背景和颜色必须发生变化。背景没有问题，但对于图标，事实证明它只会在我将鼠标悬停在其上时改变颜色，而不是链接中的任何位置。也就是说，首先出现背景，然后当您将光标拖动到图标本身时，其颜色会发生变化。如何修复它，以便当鼠标悬停在链接的任何区域时图标立即改变颜色？附上所有涉及的代码。

.list-social {
  display: flex;
}

.social-link {
  display: block;
  padding: 12px;
  width: 44px;
  height: 44px;
}

  width: 20px;
  height: 20px;
  fill: var(--icon-color);
}

.social-link:hover {
  background-color: var(--accent-color);

}

.social-icon:hover {
  fill: var(--white);

我已经尝试了我想到的一切，但仍然一无所获。

大家好。添加到列表时发生错误 CS1729 - “Person”不包含接受 0 个参数的构造函数 请告诉我如何修复它。

List<Person> persons = new List<Person>();
persons.Add( new Person { Name = "Bob", Age = 10 });

class Person
{
    public string Name;
    public int Age;

    public Person(string name, int age)
    {
        Name = name;
        Age = age;
    }
}

有两种形式，一类。从主窗体我打开第二个：

private void button1_Click(object sender, EventArgs e)
        {
            Form2 form2 = new Form2();
            this.Hide();
            form2.ShowDialog();
            this.Close();
        }

在另一个类中，我还为第二种形式创建了一个对象

Form2 form2 = new Form2();

并且在这一行上它会抛出一个异常 System.StackOverflowException。我没有在第二个表单上创建对象。你怎么能解决这个问题？毕竟我需要通过这个类的方法来改变第二个窗体上的组件。这是整个代码：

 public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            Form2 form2 = new Form2();
            this.Hide();
            form2.ShowDialog();
            this.Close();
        }
    }

public partial class Form2 : Form
    {
        Ans ans = new Ans();
        private int index = -1;

        public Form2()
        {
            InitializeComponent();
            ans.Test(radioButton1, radioButton2);

            Shown += Form1_Shown15;
        }

        private void radioButton_Click(object sender, EventArgs e)
        {
            RadioButton button = sender as RadioButton;

            if (button == radioButton1) { index = 0; }
            if (button == radioButton2) { index = 1; }
        }

        private async void Form1_Shown25(object sender, EventArgs e)
        {
            verticalProgressBar1.Value = 100;
            for (int i = 25 * 60; i > 0; i--)
            {
                verticalProgressBar1.Value = i * 100 / (25 * 60);
                await Task.Delay(1000);
            }
            Close();
        }

        private void button3_Click(object sender, EventArgs e)
        {
            try
            {
                ans.Correct(index);

                radioButton1.Checked = false;
                radioButton2.Checked = false;

                index = -1;
            }
            catch { return; }

            ans.Index++;

            if (ans.Index > 47)
            {
                MessageBox.Show();
                return;
            }
            ans.Test(radioButton1, radioButton2);
        }
    }
public class Ans
{
 Form2 form2 = new Form2();

        private List<string> test = new List<string>()
        { };

        private bool[,] boolTest =
        { };

        public int correct = 0;

        public int TestIndex { get; set; }
        public int Index { get; set; }

        public string GetCorrect { get; set; }

        public void Test(Control control1, Control control2)
        {
            control1.Text = test[TestIndex];
            TestIndex++;
            control2.Text = test[TestIndex];
            TestIndex++;
        }

        public void Correct(int i)
        {
            SystemSounds.Exclamation.Play();
            #region 1-10
            //1
            if (Index == 0)
            {
                if (boolTest[0, i] == true)
                {
                    form2.pictureBox2.BackColor = Color.Green;
                    form2.label2.Text = "";
                    correct++;
                    return;
                }
                else
                {
                    form2.pictureBox2.BackColor = Color.Red;
                    form2.label2.BackColor = Color.Red;
                }
            }           
        }
    }

我需要做一个 25 分钟的计时器，它会在时间到期时关闭表单。在这种情况下，应该有一个显示这 25 分钟的进度条。我尝试这样：

private void Form2_Load(object sender, EventArgs e)
        {
            progressBar1.Maximum = 25 * 60 * 1000;
            Timer MyTimer = new Timer();
            MyTimer.Interval = (25 * 60 * 1000); // 25 mins
            MyTimer.Tick += new EventHandler(MyTimer_Tick);
            MyTimer.Start();
        }

        private void MyTimer_Tick(object sender, EventArgs e)
        {
            count++;
            if (count <= 25 * 60 * 1000)
                progressBar1.Value = count;
            MessageBox.Show("The form will now be closed.", "Time Elapsed");
            this.Close();
        }

但是根据这段代码的结果，progressBar 什么都不显示。错误在哪里？并且progressBar可以垂直设置吗？

程序中有三个测试问题。这是主要的表单代码：

public partial class TestsForm : Form
    {
        private Ans ans = new Ans();

        private int index = -1;

        public TestsForm()
        {
            InitializeComponent();
     
            ans.Question(groupBox1);
            ans.Test(firstRadioButton, secondRadioButton, thirdRadioButton, fourthRadioButton);
            resultLabel.Text = ans.GetCorrect;
        }

        private void radioButton_Click(object sender, EventArgs e)
        {
            RadioButton button = sender as RadioButton;

            if (button == firstRadioButton) { index = 0; }
            if (button == secondRadioButton) { index = 1; }
            if (button == thirdRadioButton) { index = 2; }
            if (button == fourthRadioButton) { index = 3; }
        }

        private void answerButton_Click(object sender, EventArgs e)
        {
            try
            {
                ans.Correct(index, resultLabel);

                firstRadioButton.Checked = false;
                secondRadioButton.Checked = false;
                thirdRadioButton.Checked = false;
                fourthRadioButton.Checked = false;

                index = -1;
            }
            catch { return; }

            ans.Index++;

            if (ans.Index > 3) { MessageBox.Show("Congratulations!!!"); return; }

            ans.Question(groupBox1);
            ans.Test(firstRadioButton, secondRadioButton, thirdRadioButton, fourthRadioButton);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.Close();
        } 
    }

这是 Ans 类的代码：

        private List<string> questions = new List<string>() { "Сколько будет два плюс два?", "Третья планета от Солнца?", "Какая из пречисленых планет не имеет твердой поверхности?" };
        private List<string> answers = new List<string>() { "4", "Земля", "Юпитер" };
        private List<string> test = new List<string>() { "5", "6", "4", "2", "Земля", "Марс", "Меркурий","Луна", "Плутон", "Юпитер", "Венера","Марс" };

        private bool[,] boolTest = { { false, false, true, false }, { true, false, false, false }, { false, true, false ,false} };

        private int correct = 0;

        public int TestIndex { get; set; }
        public int Index { get; set; }

        public string GetCorrect { get; set; }

        public void Question(Control control)
        {
            control.Text = questions[Index];
        }

        public void Test(Control control1, Control control2, Control control3, Control control4)
        {
            control1.Text = test[TestIndex];
            TestIndex++;
            control2.Text = test[TestIndex];
            TestIndex++;
            control3.Text = test[TestIndex];
            TestIndex++;
            control4.Text = test[TestIndex];
            TestIndex++;
        }

        public void Correct(int i, Control control)
        {
            if (Index == 0)
            {
                if (boolTest[0, i] == true)
                {
                    MessageBox.Show("Correct");
                    correct++;
                    GetCorrect = "Правильные ответы: " + correct.ToString() + " из 3";
                    control.Text = GetCorrect;

                    return;
                }
                else { MessageBox.Show("Not correct"); return; }
            }

            if (Index == 1)
            {
                if (boolTest[1, i] == true)
                {
                    MessageBox.Show("Correct");
                    correct++;
                    GetCorrect = "Правильные ответы: " + correct.ToString() + " из 3";
                    control.Text = GetCorrect;

                    return;
                }
                else { MessageBox.Show("Not correct"); return; }
            }

            if (Index == 2)
            {
                if (boolTest[2, i] == true)
                {
                    MessageBox.Show("Correct");
                    correct++;
                    GetCorrect = "Правильные ответы: " + correct.ToString() + " из 3";
                    control.Text = GetCorrect;

                    return;
                }
                else { MessageBox.Show("Not correct"); return; }
            }          
        }

问题是第四个 radioButton 不起作用。但是，如果在此之前您单击其他人并在最后单击第四个，那么它会记住以前的 RadioButton 并给出其结果。在此先感谢您的帮助！这是来自 Designer.cs 的自动生成的代码

有一个文本文档，其中将以下内容写在一个列中（示例）：11123 大纲，11124 苦艾酒，11125 苦艾酒，11126 荒谬，11131 布尔利亚，11132 阿布哈兹。而且有很多这样的行，几乎 6000。它们的索引从 1000 到 6666。我以这种方式得到所有这些行

string[] lines = File.ReadAllLines(@"F:\VS Projects\Со звёздочкой\diceware.txt");

然后我形成一个 int 类型的数组，由 5 个从 1 到 6 的随机元素组成。底线是，通过这些随机数，我必须在这个索引处找到一个单词并输出 yogo。这就是我正在尝试的方式

int[] arr1 = new int[5]; //Массив с рандомными значениями, представим, что значения уже там есть.

for ( int i = 0; i < lines.Length; i++)
{
char[] textByCharacter = lines[i].ToCharArray(); //Строку перевожу в массив символов.
int yes = object1.Sravnenie(arr1, textByCharacter); //Метод, в котором я пытаюсь сравнить
if ( yes == 5)
{
textBox.Text = lines[i];
break;
}
}

比较方法本身：

public int Sravnenie(int[] numbers, char[] ch)
        {
            int yes = 0;

            int[] transfer = new int[5];
            for (int i = 0; i < 5; i++) //Беру 5, так как первые 5 символом это индекс слова
            {
                transfer[i] = Convert.ToInt32(ch[i]);
            }

            for (int i = 0; i < 5; i++)
            {
                if (numbers[i] == transfer[i])
                {
                    yes++;
                }
            }
            return yes;
        }

但最终它对我不起作用。如何决定？提前致谢！

我有一个文本文档，其中的单词写在一个列中。我得到并输出这些词是这样的：

System.IO.StreamReader file = new System.IO.StreamReader(@"F:\VS Projects\Со звёздочкой\diceware.txt");
while ((line = file.ReadLine()) != null)
{
    textBox1.AppendText(line + "\t\t");
}           

但后来事实证明，我没有添加到集合中，而是简单地移动光标。将来，我需要遍历这些行以获得特定的单词。如何写入集合？

尝试这样做：

textBox1.Lines[0] = line;

但随后它会引发 System.IndexOutOfRangeException。

此代码引发异常

Bitmap image1;
image1 = (Bitmap)pictureBox1.Image;
for (x = 0; x < image1.Width; x++)
                {
                    for (y = 0; y < image1.Height; y++)
                    {
                        image1.SetPixel(x, y, newColor);
                    }
                }

如果我不在此行的图片框中加载图像，则触发

image1.SetPixel(x, y, newColor);

如何决定？
