看来本文中的控件完全可以满足您的需求. :)

Check out this[^] CodeProject article.
It seems that the control from the article does exactly what you need. :)

这可能不是最好的方法，但是我玩过它，似乎很奏效.如果不是您要找的东西，至少应该让您入门.

This might not be the best way to do it, but I played with it and it seems to work. If it''s not quite what you were looking for it should at least get you started.

Dim intLineNumber As Integer =  RichTextBox1.GetLineFromCharIndex(RichTextBox1.SelectionStart) + 1
Dim intCharIndexOfLine As Integer = RichTextBox1.GetFirstCharIndexOfCurrentLine()
Dim intCharIndex As Integer = RichTextBox1.SelectionStart
Dim intCol As Integer = Math.Abs(intCharIndexOfLine - intCharIndex)
