String Trimming with IndexOf C#

[stilmas]

Hey guys,

I have a quick question that should be easy for the people here. If this code trims the string to give me the first half of the string (anything before the \):
<%
string mys=Request.ServerVariables["AUTH_USER"].ToString();
int n=mys.IndexOf("\\");
if (n!=-1)
{
mys=mys.Substring(n+1);
}
%>

How would I wirte it to give me the second half only? (anything after the \).
Thanks a million!

That code is giving you the second half.
If you want the first half:
mys=mys.Substring(0,n-1);

OR you could do

if (mys.indexOf("\\")!=0)
{
   string[] pieces=mys.Split("\\");
   //pieces[0] is anything before the first \
   //pieces[1] will be what comes after
   // (Note: if there are more \ in the string then there will be a pieces[2] and so on
}

Hey Plater,

I'm getting burnt. That's what I meant. Thanks for all your help.
