c# - How to remove all instances of a specific character from a string?

Question

I am trying to remove all of a specific character from a string. I have been using String.Replace, but it does nothing, and I don't know why. This is my current code:

        if (Gamertag2.Contains("^"))
        {
            Gamertag2.Replace("^" + 1, "");
        }

This just leaves the string as it was before. Can anyone please explain to me as to why?

Answer 1

You must assign the return value of String.Replace to your original string instance:

hence instead of(no need for the Contains check)

if (Gamertag2.Contains("^"))
{
    Gamertag2.Replace("^" + 1, "");
}

just this(what's that mystic +1?):

Gamertag2 = Gamertag2.Replace("^", "");
