Question

我的问题类似于https://stackoverflow.com/questions/18944437/replacing-text-between-b-and-b-with-bold-text-in-c-sharp

我想在＆lt; * strong＆gt;之间加粗字符串标签

我用

获取字符串

string pattern = @"<strong>(.*?)</strong>";
var matches = Regex.Matches(paragraf2.Range.Text, pattern)
                   .Cast<Match>()
                   .Select(m => m.Groups[1].Value)
                   .ToList();

我想我需要像

这样的东西

foreach( string a in matches)
{     
}

但我无法弄清楚要在里面写什么。

Answer 1

与您的案例相关（如果描述正确），您可以通过修改字符串来使用[https://stackoverflow.com/questions/18944437/replacing-text-between-b-and-b-with-bold-text-in-c-sharp]中给出的解决方案：

 richTextBox1.SelectedText = richTextBox1.SelectedText.Replace("<b>", "").Replace("</b>", "");

如下所示：

richTextBox1.SelectedText = richTextBox1.SelectedText.Replace("<strong>", String.Empty).Replace("</strong>", String.Empty);

或者，相应的解决方案（修改后的原始版本）如下：

private void richTextBox1_TextChanged(object sender, EventArgs e)
{
    string regexString = "(?<=<strong>)(.*?)(?=</strong>)";
    Match matches = (Regex.Match(richTextBox1.Text, regexString));

    if (matches.Success)
    {
        int index1 = richTextBox1.Find("<strong>");
        int index2 = richTextBox1.Find("</strong>");
        richTextBox1.Select(index1 + 3, ((index2) - (index1 + 3)));

        richTextBox1.SelectionFont = new Font(richTextBox1.SelectionFont.FontFamily, richTextBox1.SelectionFont.Size, FontStyle.Bold);
    }
}

有关RichTextBox字体属性的更多详细信息，请参阅以下代码段（来自Microsoft在线文档http://msdn.microsoft.com/en-us/library/system.windows.forms.richtextbox.selectionfont%28v=vs.100%29.aspx）：

private void ToggleBold()
{
   if (richTextBox1.SelectionFont != null)
   {
      System.Drawing.Font currentFont = richTextBox1.SelectionFont;
      System.Drawing.FontStyle newFontStyle;

      if (richTextBox1.SelectionFont.Bold == true)
      {
         newFontStyle = FontStyle.Regular;
      }
      else
      {
         newFontStyle = FontStyle.Bold;
      }

      richTextBox1.SelectionFont = new Font(
         currentFont.FontFamily, 
         currentFont.Size, 
         newFontStyle
      );
   }
}

作为har07在评论中说明你可以像

一样使用它

       string pattern = @"<strong>(.*?)</strong>";
       var matches = Regex.Matches(paragraf2.Range.Text, pattern)
               .Cast<Match>()
               .Select(m => m.Groups[1].Value)
               .ToList();
       Word.Find findObject = Application.Selection.Find;
       foreach( string a in matches){ 
            findObject.ClearFormatting();
            findObject.Text = a;
            findObject.Replacement.ClearFormatting();
            findObject.Replacement.Font.Bold = 1;
            object replaceAll = Word.WdReplace.wdReplaceAll;
            findObject.Execute(ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref replaceAll, ref missing, ref missing, ref missing, ref missing);  
           }
