To get the actual XAML created by the user inside of the RichTextBox:
要获取用户在 RichTextBox 内创建的实际 XAML：
TextRange tr = new TextRange(myRichTextBox.Document.ContentStart,
myRichTextBox.Document.ContentEnd);
MemoryStream ms = new MemoryStream();
tr.Save(ms, DataFormats.Xaml);
string xamlText = ASCIIEncoding.Default.GetString(ms.ToArray());
EDIT: I don't have code in front of me to test, but an instance of the TextRangetype has a Save(to stream) method that takes a DataFormatsparameter, which can be DataFormats.Rtf
编辑：我面前没有要测试的代码，但是该TextRange类型的实例有一个Save（流）方法，它接受一个DataFormats参数，可以是DataFormats.Rtf

There are 2 RichTextBox classes, one from the winforms framework and one from the WPF framework:
有 2 个 RichTextBox 类，一个来自 winforms 框架，一个来自 WPF 框架：
System.Windows.Controls.RichTextBox wpfBox;
System.Windows.Forms.RichTextBox winformsBox;
Only the Winforms RichTextBox has an Rtf property, the other has a Document property which contains a FlowDocument.
只有 Winforms RichTextBox 具有 Rtf 属性，另一个具有包含 FlowDocument 的 Document 属性。
