按钮示例

有人用过带有切角的按钮吗？互联网上有关于如何做到这一点的提示（使用clip-path伪元素）。

但任务很复杂，因为您需要将效果附加到这样的按钮，即hover-e 处的发光。

这是可行的，但由于clip-path发光，它不会向外扩散，并且伪元素很难突出显示。

也许有人已经解决了类似的问题

我将一些 Unity 场景对象保存到 XML 文件中，以便随时加载此状态并继续游戏。保存到文件没有问题，但读取很糟糕 - 代码将 XML 读取到结构中的第一个结束对象，然后完成读取，尽管这还不到整个文件的 1%。这是一个没有组件等的示例文件：

<?xml version="1.0"?>
<ArrayOfSerializableObject xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <SerializableObject>
    <Name>1</Name>
    <Tag></Tag>
    <Position></Position>
    <Rotation></Rotation>
    <Scale></Scale>
    <Children>
      <SerializableObject>
        <Name>2</Name>
        <Tag></Tag>
        <Position></Position>
        <Rotation></Rotation>
        <Scale></Scale>
        <Children>
          <SerializableObject>
            <Name>3</Name>
            <Tag></Tag>
            <Position></Position>
            <Rotation></Rotation>
            <Scale></Scale>
            <Children>
              <SerializableObject>
              <Name>4</Name>
              <Tag></Tag>
              <Position></Position>
              <Rotation></Rotation>
              <Scale></Scale>
              <Children />
              <Components></Components>
            </Children>
            <Components></Components>
          </SerializableObject>
          <SerializableObject>
            <Name>5</Name>
            <Tag></Tag>
            <Position></Position>
            <Rotation></Rotation>
            <Scale></Scale>
            <Children />
            <Components></Components>
          </SerializableObject>
        </Children>
        <Components></Components>
      </SerializableObject>
    </Children>
    <Components />
  </SerializableObject>
</ArrayOfSerializableObject>

结果，我将收到以下结构中的对象：

-1
--2
---3
----4

5 及以后将不再被读取，因为代码应该到达文件末尾。

事实上，这里是保存和读取代码本身（或者更正确地说，是它的一个片段）：

using System.Collections;

            string key = reader.GetAttribute("Key");
            string value = reader.GetAttribute("Value");
            Dictionary.Add(key, value);
            reader.Read();
        }
        reader.ReadEndElement();
    }

目前，我的目标是培训成为一名 ASP.NET Core 开发人员（之前我学习过 .NET Framework，但决定改变我的计划）。关键问题是我是否需要学习.NET 平台本身，据我所知，ASP.NET 是基于该平台的。如果是这样，怎么办？ Jeffrey Richter 的书“CLR via C#”是为 .NET Framework 编写的，但我还没有找到任何类似的针对 .NET 的书。在开源中我没有找到任何用 C# 编写 .NET 项目的手册。
