logon.Substring(logon.IndexOf("\\")+1);

Note the double slash...

...hope that solves it.
alldayAuthor Commented:
i did try with double slash too but it does not  return the desired result

for an example:

i'm getting logon_user  -- US\UserName

i want to trim "US\"

and get the only UserName

when i use the double slash it does not trim "US\" rather it gives me "US\UserName"

hope im clear

thanks

// Get username
DomainAndUsername = ...
string UserName = DomainAndUsername.Substring(DomainAndUsername.IndexOf(@"\") + 1);
