如何在状态栏的文本框中显示行位置?

Question

我添加了一个StatusStrip控件，并在其中放置了一个StatusLabel。但是现在我想知道如何将它连接到我的文本框，以显示行号和光标的位置，如:" line 2, Row 6"。

Thank you

1. 获取文本框中插入符号的索引:

   c#

   int caretIndex = textBox.SelectionStart;
   

   VB。

   Dim caretIndex As Integer = textBox.SelectionStart
   

2. 从插入符号索引中获取行号:

   c#

   int lineNumber = textBox.GetLineFromCharIndex(caretIndex);
   

   VB。

   Dim lineNumber As Integer = textBox.GetLineFromCharIndex(caretIndex)
   

3. 获取当前行的字符索引:

   c#

   Point characterXY = textBox.GetPositionFromCharIndex(caretIndex);
   int characterIndex = textBox.GetCharIndexFromPosition(characterXY);
   

   VB。

   Dim characterXY As Point = textBox.GetPositionFromCharIndex(caretIndex)
   Dim characterIndex As Integer = textBox.GetCharIndexFromPosition(characterXY)
