C# Textbox Auto Scroll To End ScrollToCaret Scrolling Textbox

Many of my sample C# codes,
I use textbox to write the results.

When textbox is multiline property set to true, and when I insert text into it,
I want it to auto scroll to the last line.

Here is a simple way to auto scrolling textbox.

 textbox1.SelectionStart = textbox1.Text.Length;
 textbox1.ScrollToCaret();
 textbox1.Refresh();

Textbox SelectionStart will force the textbox control to select the last part of the text,
and ScrollToCaret() function will auto scroll textbox to the end.
