How do I remove the last character from a string only when it is a comma?

Question

I have:

String test = "Hello,";
String test2 = "Hello";

I want to replace the last character if it is a comma with an empty string. I currently have:

String var = test.Remove(str.Length - 1, 1) + "";
String var = test2.Remove(str.Length - 1, 1) + "";

That would always replace the last character, even if it was not a comma.

What if the string ends with multiple consecutive commas? Should they all be removed, or only the last character? — Lance U. Matthews, Nov 15 '19 at 00:48

You can use .TrimEnd like so:

String test = "Hello,";
test = test.TrimEnd(',');
