According to this it does have a Text property
据此，它确实有一个 Text 属性

You can also try the "Lines" property if you want the text broken up as lines.
如果您希望将文本分解为行，您也可以尝试“行”属性。

There was a confusion between RichTextBox in System.Windows.Formsand in System.Windows.Control
System.Windows.Forms和System.Windows.Control 中的RichTextBox 之间存在混淆
I am using the one in the Control as I am using WPF. In there, there is no Text property, and in order to get a text, I should have used this line:
我正在使用控件中的一个，因为我正在使用 WPF。在那里，没有 Text 属性，为了获得文本，我应该使用这一行：
string myText = new TextRange(transcriberArea.Document.ContentStart, transcriberArea.Document.ContentEnd).Text;
thanks
谢谢

The WPF RichTextBox has a Documentproperty for setting the content a laMSDN:
WPF RichTextBox 有一个Document用于设置MSDN内容的属性：
// Create a FlowDocument to contain content for the RichTextBox.
FlowDocument myFlowDoc = new FlowDocument();
// Add paragraphs to the FlowDocument.
myFlowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 1")));
myFlowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 2")));
myFlowDoc.Blocks.Add(new Paragraph(new Run("Paragraph 3")));
RichTextBox myRichTextBox = new RichTextBox();
// Add initial content to the RichTextBox.
myRichTextBox.Document = myFlowDoc;
You can just use the AppendTextmethod though if that's all you're after.
AppendText如果这就是您所追求的，您可以只使用该方法。
Hope that helps.
希望有帮助。

"Extended WPF Toolkit" now provides a richtextbox with the Text property.
“扩展 WPF 工具包”现在提供带有 Text 属性的富文本框。
You can get or set the text in different formats (XAML, RTF and plaintext).
您可以获取或设置不同格式（XAML、RTF 和纯文本）的文本。

RichTextBox rtf = new RichTextBox();
System.IO.MemoryStream stream = new System.IO.MemoryStream(ASCIIEncoding.Default.GetBytes(yourText));
rtf.Selection.Load(stream, DataFormats.Rtf);
OR
或者
rtf.Selection.Text = yourText;

Using two extension methods, this becomes very easy:
使用两种扩展方法，这变得非常容易：
public static class Ext
{
public static void SetText(this RichTextBox richTextBox, string text)
{
richTextBox.Document.Blocks.Clear();
richTextBox.Document.Blocks.Add(new Paragraph(new Run(text)));
}
public static string GetText(this RichTextBox richTextBox)
{
return new TextRange(richTextBox.Document.ContentStart,
richTextBox.Document.ContentEnd).Text;
}
}
