将图像插入文本

  • 772

需要在 中RichTextBox分别插入文字中文字的位置图片，使左右换行。

我目前正在使用这样的东西。

string[] messageSplit = message.Split(' ');
FlowDocument doc = new FlowDocument();
Paragraph paragraph = new Paragraph();

for (int i = 0; i < messageSplit.Length; ++i) {
            string str = messageSplit[i];
            if (str.Contains("${emoteId=")) {

                string id = ...
                Image image = new Image();
                image.Source = (ImageSource)((new ImageSourceConverter()).ConvertFromString($@"emotes/{id}.png"));

                BlockUIContainer cont = new BlockUIContainer(image);
                Figure figure = new Figure(cont);
                figure.Width = (new FigureLength(24));
                figure.WrapDirection = WrapDirection.Both;
                figure.VerticalAnchor = FigureVerticalAnchor.PageTop;
                figure.HorizontalAnchor = FigureHorizontalAnchor.PageLeft;

                paragraph.Inlines.Add(figure);
            } else {
                paragraph.Inlines.Add(new Run(str));
            }
        doc.Blocks.Add(paragraph);
        MessageText.Document = doc;

但是有了这样的插入，所有被转移到顶部的文本，所有的图片都出现在了底部。

如何正确插入文本？

文本本身看起来像这样qqq ${emoteId=4} www ${emoteId=5} ${emoteId=20} eee

    string[] messageSplit = message.Split(' ');
            FlowDocument doc = new FlowDocument();
            Paragraph paragraph = new Paragraph();

            for (int i = 0; i < messageSplit.Length; ++i) {
                string str = messageSplit[i];
                if (str.Contains("${emoteId=")) {
                    string id = ...


                    Image image = new Image();
                    image.Source = (ImageSource)((new ImageSourceConverter()).ConvertFromString($@"emotes/{id}.png"));
                    image.Width = 28;

                    InlineUIContainer inlineUIContainer = new InlineUIContainer(image);
                    paragraph.Inlines.Add(inlineUIContainer);
                    paragraph.Inlines.Add(" ");
                } else {
                    paragraph.Inlines.Add(str + " ");
                }
            }

            doc.Blocks.Add(paragraph);
            MessageText.Document = doc;
