推荐答案

正如Bernhard在评论中提到的那样，您正在查看Windows窗体控件的文档。您需要查看WPF控件的文档，该控件没有 Text 属性：



RichTextBox类（System.Windows.Controls）| Microsoft Docs [ ^ ]



要获取或设置文本，您可以使用此StackOverflow答案 [ ^ ] ：

As Bernhard mentioned in the comments, you're looking at the documentation for the Windows Forms control. You need to look at the documentation for the WPF control, which doesn't have a Text property:

RichTextBox Class (System.Windows.Controls) | Microsoft Docs[^]

To get or set the text, you can use the code from this StackOverflow answer[^]:

' Set the text:
richTextBox1.Document.Blocks.Clear()
richTextBox1.Document.Blocks.Add(new Paragraph(new Run("The text...")))

' Read the text:
Dim text As String = New TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text

如何：从中提取文本内容RichTextBox | Microsoft Docs [ ^ ]

如何：保存，加载和打印RichTextBox内容Microsoft Docs [ ^ ]
