string s = "G618964";

if (s[0] == 'G')
{
s.Remove(0,1);
}

// after stepping through this code, s = "G618964"
// I was anticipating s = "618964";

Any insight you may provide is appreciated

Thanks, - dog

Hi,

.net strings are immutable (it means string is always persistent).

s.Remove(..) gives you another string. The s for all that refers to the value
which cannot be changed (http://www.codeproject.com/dotnet/StringsInDotNet.asp).
So, Ed gives you example to replace s variable to another value.
