I have a the following string:

C:\Documents and Settings\test\My Documents\My Pictures\Logo2.gif

How do I just get the

Logo2.gif

out of the string

I'm using

strFileNamePath.Substring(strFileNamePath.LastIndexOf("\\"), strFileNamePath.Length);

But I get an error all the time

"Index and length must refer to a location within the string. Parameter name: length "

Many thanks

Use:

            string fullpath = @"C:\Documents and Settings\test\My Documents\My Pictures\Logo2.gif";
            string filename = System.IO.Path.GetFileName(fullpath);

Try

strFileNamePath.Substring(strFileNamePath.LastIndexOf("\\") + 1);


Or Try the following two ways

1)
result = (new FileInfo(strFileNamePath)).Name;

2)
result = Regex.Match(strFileNamePath, "[^\\\\]+$").Value;

strFileNamePath.Length is the length of both filename and path.
