问题描述

从富文本框中的 rtf 复制时出现问题

I have a problem when copying from rtf in richtextbox

当序列化丢失的财产时.//不序列化属性bold"和color"和size"

when serializing lost property. // NOT SERIALIZE properties "bold" and "color" and "size"

所有代码:

string ConvertXamlToString(FlowDocument fd)
{
 string format = "@TAG@{0}:{1}@TAG@";

 FlowDocument ss = new FlowDocument();

 for (int i = 0; i < fd.Blocks.Count; i++)
 {
  var block = (fd.Blocks as BlockCollection).ElementAt(i);
  if (block is Paragraph)
  {
   var p = new Paragraph();
   for (int y = 0; y < ((Paragraph)block).Inlines.Count; y++)
   {
    var inline = ((Paragraph)block).Inlines.ElementAt(y);
    if (inline is InlineUIContainer)
    {
     var elem = ((InlineUIContainer)inline).Child;
     if (elem is FlashControl)
     {
      TextBox mc = new TextBox() { Text = string.Format(format, "FlashControl", (elem as FlashControl).Flashp.Source) };
      p.Inlines.Add(mc);
     }
     else if (elem is MusicControl)
     {
      MusicControl mc = new MusicControl((elem as MusicControl).Path_file);
      p.Inlines.Add(mc);
     }
     else if (elem is Image)
     {
      Image mc = new Image();
      Image Last = (elem as Image);
      try
      {
       if (Last.Source is System.Windows.Media.Imaging.BitmapImage)
       {
        mc.Source = new BitmapImage(new Uri(((System.Windows.Media.Imaging.BitmapImage)(Last.Source)).UriSource.AbsolutePath));
       }
       else if(Last.Source is System.Windows.Media.Imaging.BitmapImage)
       {
        mc.Source = new BitmapImage(new Uri(((System.Windows.Media.Imaging.BitmapImage)(Last.Source)).UriSource.ToString()));
       }
      }
      catch { }
      p.Inlines.Add(mc);
     }
     else
     {
      p.Inlines.Add(elem);
     }
    }
    else if (inline is Run)
    {
     Run r = (inline as Run);
     string rSer = XamlWriter.Save(r);
     var inl1 = XamlReader.Parse(rSer);
     p.Inlines.Add(inl1 as Run);
    }
    else if (inline is Span)
    {
     Span r = (inline as Span);
     string rSer = XamlWriter.Save(r);// NOT SERIALIZE properties "bold" and "color" and "size"
     var inl1 = XamlReader.Parse(rSer);
     p.Inlines.Add(inl1 as Span);
    }
    else
    {
    }
   }
   ss.Blocks.Add(p);
  }
 }

 string aaa = XamlWriter.Save(ss);

 richtextbox.Document.Blocks.Clear();

 object f = XamlReader.Parse(aaa);
 richtextbox.Document = f as FlowDocument;
 return aaa;
}

代码的主要部分:

else if (inline is Run)
{
    Run r = (inline as Run);
    string rSer = XamlWriter.Save(r);
    var inl1 = XamlReader.Parse(rSer);
    p.Inlines.Add(inl1 as Run);
}
else if (inline is Span)
{
    Span r = (inline as Span);
    string rSer = XamlWriter.Save(r);// NOT SERIALIZE properties "bold" and "color" and "size"
    var inl1 = XamlReader.Parse(rSer);
    p.Inlines.Add(inl1 as Span);
}

如果您手动输入所有内容，则一切正常.我该如何解决这个问题?

if you enter everything manually, all is well. How do I fix this?

推荐答案

嗯，粗体和大小本身并不是属性，它们是 Span 的衍生物，你可能需要解析它们通过迭代 Span 的 Inlines 属性来单独保留它们

Hmm, well bold and size aren't properties as such, they're derivatives of Span, you might need to parse them individually by iterating the Inlines property of your Span to preserve them
