我有一些HTML，我正在使用Microsoft提供的库转换为XAML
string t = HtmlToXamlConverter.ConvertHtmlToXaml(mail.HtmlDataString,true);
现在，从How to insert XAML into RichTextBox?我使用以下内容：
private static FlowDocument SetRTF(string xamlString)
{
StringReader stringReader = new StringReader(xamlString);
System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(stringReader);
Section sec = XamlReader.Load(xmlReader) as Section;
FlowDocument doc = new FlowDocument();
while (sec.Blocks.Count > 0)
doc.Blocks.Add(sec.Blocks.FirstBlock);
return doc;
}
但不幸的是，这仍然会崩溃= /有没有人知道如何在RichTextBox中显示XAML文本？
编辑：html的例子我正在尝试转换

我认为它会在Add()上崩溃，因为您要添加一个已经拥有逻辑父级的FrameworkContentElement。您必须先从其父级中删除Block，然后才将其添加到其他集合中。试试这个：
private static FlowDocument SetRTF(string xamlString)
{
StringReader stringReader = new StringReader(xamlString);
System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(stringReader);
Section sec = XamlReader.Load(xmlReader) as Section;
FlowDocument doc = new FlowDocument();
while (sec.Blocks.Count > 0)
{
var block = sec.Blocks.FirstBlock;
sec.Blocks.Remove(block);
doc.Blocks.Add(block);
}
return doc;
}
然后事情变得简单得多。做一个：
private static FlowDocument SetRTF(string xamlString)
{
StringReader stringReader = new StringReader(xamlString);
System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(stringReader);
return XamlReader.Load(xmlReader) as FlowDocument;
}
richTextBox.Document = SetRTF(xamlString);

或短
private FlowDocument StringToFlowDocument(string s)
{
var xamlString = string.Format("<FlowDocument xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" xmlns:x=\"http://schemas.microsoft.com/winfx/2006/xaml\"><Paragraph>{0}</Paragraph></FlowDocument>", s);
return XamlReader.Parse(xamlString) as FlowDocument;
}
答案 2 :(得分：0)
private static FlowDocument SetRTF(string xamlString)
{
StringReader stringReader = new StringReader(xamlString);
System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(stringReader);
FlowDocument doc = (FlowDocument)XamlReader.Load(xmlReader);
return doc;
}
