Getting file name from string

Question

Could you help me find the file name from the string. Now I have one line of content, such as "C: \ xxxx \ xxxx \ xxxx \ abc.pdf". But I want only the ie file name. abc.pdf. How does this come about with string functions?

string file = Path.GetFileName(full);
Console.WriteLine(file); // abc.pdf

Console.WriteLine("GetFileName('{0}') returns '{1}'",
