How can I display the line position in a TextBox on the status bar?

I have added a 开发者_高级运维StatusStrip control and placed a StatusLabel inside of it. But now I want to know how to connect it to my TextBox to show the line number and position of the cursor, like: "Line 2, Row 6".

Thank you

1. Get the index of the caret in the TextBox:

   C#

   int caretIndex = textBox.SelectionStart;
   

   VB.NET

   Dim caretIndex As Integer = textBox.SelectionStart
   

2. Get the line number from the caret index:

   C#

   int lineNumber = textBox.GetLineFromCharIndex(caretIndex);
   

   VB.NET

   Dim lineNumber As Integer = textBox.GetLineFromCharIndex(caretIndex)
   

3. Get the character index in the current line:

   C#

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

   VB.NET

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