推荐答案

使用属性System.Windows.Forms.RichTextBox.SelectionStart System.Windows.Forms.RichTextBox.SelectionLength，请参见http://msdn.microsoft.com/en-us/library/system.windowss.forms.richtextbox.aspx [^ ].

不清楚是什么问题.可能这与表单协作有关.最好的方法是在表单类中实现适当的接口.查看我过去的答案:
如何在列表框之间复制所有项目两种形式 [ ^ ].

Use the properties System.Windows.Forms.RichTextBox.SelectionStart System.Windows.Forms.RichTextBox.SelectionLength, see http://msdn.microsoft.com/en-us/library/system.windows.forms.richtextbox.aspx[^].

Not clear what the problem is. Probably this is about form collaboration. The best way is to implement appropriate interface in form class. See my past answer:
How to copy all the items between listboxes in two forms[^].
