Question

I have something like this:

string[] split = ListOfUsers.Split(new Char[] { ';', ',', ' ' });

Each string in “split” has an “@” sign at the beginning, and I want to get rid of it. What would be the ideal way to get the substring of this array, without getting into a for loop. Can I use Linq instead?

Thanks for looking 🙂

There is an overload of String.Trim that does exactly this: removes the specified characters from the beginning and end of a string:

string[] split = ListOfUsers.Split(new Char[] { ';', ',', ' ' });
string[] trimmed = split.Select(s => s.Trim('@')).ToArray();

If your strings contain multiple @s in the beginning or end with a @ this will do more than you intended. In that case, you can also simply use String.Substring:

string[] split = ListOfUsers.Split(new Char[] { ';', ',', ' ' });
string[] trimmed = split.Select(s => s.Substring(1)).ToArray();
