In my textbox I enter some numbers like 123,456,789,. If the last character of my entered number is "," then I need to remove it (",") otherwise I shouldn't remove anything

How do I do that? Please help me with a solution.

Thanks.

You could try:
textbox.text.TrimEnd({','})

A disadvantage (or advantage) is that all comma's are removed at the end and not just one.

Otherwise just check the last character in the string and remove this if it is a comma.

Good luck!
