c# - 将 RTF 字符串转换为 XAML 字符串

Question

在 C# 中将 RTF 字符串转换为 XAML 字符串的最有效方法是什么？我想使用 System.Windows.Documents.XamlRtfConverter.ConvertRtfToXaml(string rtfContent) 但遗憾的是该类是内部类。

您可以从 RTF 字符串转换为 XAML 字符串，但会丢失图像:

 var rtf = File.ReadAllText(rtfFileName);
 var doc = new FlowDocument();
 var range = new TextRange(doc.ContentStart, doc.ContentEnd);
 using (var inputStream = new MemoryStream(Encoding.ASCII.GetBytes(rtf)))
 {
    range.Load(inputStream, DataFormats.Rtf);
    using (var outputStream = new MemoryStream())
    {
       range.Save(outputStream, DataFormats.Xaml);
       outputStream.Position = 0;
       using (var xamlStream = new StreamReader(outputStream))
       {
          var xaml = xamlStream.ReadToEnd();
          File.WriteAllText(xamlFileName, xaml);
       }
    }
 }

要保存图像，您必须从 RTF 字符串转到 XAML 包:

 var rtf = File.ReadAllText(rtfFileName);
 var doc = new FlowDocument();
 var range = new TextRange(doc.ContentStart, doc.ContentEnd);
 using (var inputStream = new MemoryStream(Encoding.ASCII.GetBytes(rtf)))
 {
    range.Load(inputStream, DataFormats.Rtf);
    using (var outputStream = new FileStream(xamlFileName, FileMode.Create))
    {
       range.Save(outputStream, DataFormats.XamlPackage);
    }
 }
