推荐答案

使用 ^ ]

这是您不应该要做的事情:不为，并且不要将其分配给属性Text.不要尝试使用属性Rtf做类似的事情. (这仅适用于System.Windows.Forms.RichTextBox，不能用于WPF System.Windows.Controls.RichTextBox.)

这是您应该做的:使用正确的SelectionStart和SelectionEnd选择所需的文本，然后将属性SelectedText分配给string.Empty.

另外，请注意:这些控件具有撤消功能；您可以使用它.

请始终标记要使用的UI库，不要让专家做双重工作！

Here is what you should not do: do not calculate new text for the instance of RichTextBox and do not assign it to the property Text. Do not try to do something like that with the property Rtf. (This is applicable to System.Windows.Forms.RichTextBox only, you cannot do it for WPF System.Windows.Controls.RichTextBox.)

Here is what you should do: select the text you need using the properly SelectionStart and SelectionEnd, then assign the property SelectedText to string.Empty.

Also, pay attention: these controls have Undo functionality; you can use it.

See:

Please, always tag UI library you want to use, don''t make experts doing double work!
