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

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?

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("^", "");
