Trim away the last part of a string
-
Hi all, i just want to know how to trim away the last part of a string in a variable... I have the following: string strNum = "0821234567,0721234567,0831234567," string strNum2 = ""; if(strNum.EndsWith(",")) { } "Many of life's failures are people who did not realize how close they were to success when they gave up."

You create a new string from the part of the string that you want to keep:
strNum = strNum.SubString(0, strNum.Length - 1);--- b { font-weight: normal; }
Thank you for your time... :)

Hmm, you should consider using "Trim" or "TrimEnd" instead of "Substring" - after all, you want to - well - trim :) It will save you the clumpsy "if" construction as well.
Thank you, the first one worked. so after i checked if there is a "," at the end of the string it just leaves it out. but i'll use the trim end next time. ;) thanks.

On another note, something faster, and optimized than substring or trimending (think what shall happen calling substring on a very huge string?) strNum[strNum.Length-1] = string.Empty; There are few scenarios where this will be the best and others where this wont be a better idea.

Two problems with your code: strNum[index] is a char. string.Empty is a string. You can't assign a string to a char. Strings can't be changed. Hence strNum[index] is a read-only indexer. So I do not see how this should work. Using a StringBuilder might help if the strings are repeatedly modified, but for a single trim operation it would not make any sense.
