Question

C# 怎样获取RichTextBox光标位置

Answer 1

行值.Text=(1+richTextBox1.GetLineFromCharIndex(richTextBox1.SelectionStart)).ToString();

列值.Text=(1+richTextBox1.SelectionStart-(richTextBox1.GetFirstCharIndexFromLine(1+richTextBox1.GetLineFromCharIndex(richTextBox1.SelectionStart)-1))).ToString();

看那个算法可能眼都花了，不过你可以复制到你的原代码试试。本人测试成功通过！

Answer 2

richtextbox.SelectionStart=richtextbox.TextLength;
richtextbox.Focus();

Answer 3

获取光标所在richTextBox1的位置
private void richTextBox1_SelectionChanged(object sender, EventArgs e)
{
Text = richTextBox1.SelectionStart.ToString();
}
