问题描述

如何获取Richtextbox的当前光标位置

tnx

how do i get the current cursor position of richtextbox

tnx

推荐答案

使用属性SelectionStart.

如果SelectionLength不为零，则该问题没有确切含义:SelectionStart和SelectionStart + SelectionLength都可以视为光标位置.当用户按下向左或向右键取消选择文本时，任何一个点都可以成为光标位置-请尝试查看.

Use the property SelectionStart.

If SelectionLength not zero, the question has no exact meaning: both SelectionStart and SelectionStart + SelectionLength could be considered as the cursor position. Either point can became a cursor position when the text is deselected when a user presses left or right key — try it to see.
