Could you help me for finding the file name from the string. Now i have one string of content like "C:\xxxx\xxxx\xxxx\abc.pdf". But i want only the file name ie. abc.pdf. How it will get by using string functions?

Use Path.GetFileName:
string full = @"C:\xxxx\xxxx\xxxx\abc.pdf";
string file = Path.GetFileName(full);
Console.WriteLine(file); // abc.pdf
Note that this assumes the last part of the name is a file - it doesn't check. So if you gave it "C:\Windows\System32" it would claim a filename of System32, even though that's actually a directory. (Passing in "C:\Windows\System32\" would return an empty string, however.) You can use File.Exists to check that a file exists and is a file rather than a directory if that would help.
This method also doesn't check that all the other elements in the directory hierarchy exist - so you could pass in "C:\foo\bar\baz.txt" and it would return baz.txt even if foo and bar don't exist.

@Dilse Naaz: I don't understand your comment, I'm afraid. The code I've shown deals with strings.
Use the Path.GetFileName() Method
(Edited) sample from the MSDN-page:
string fileName = @"C:\xxxx\xxxx\xxxx\abc.pdf";
string path = @"C:\xxxx\xxxx\xxxx\";
string path2 = @"C:\xxxx\xxxx\xxxx";
string result;
result = Path.GetFileName(fileName);
Console.WriteLine("GetFileName('{0}') returns '{1}'",
fileName, result);
result = Path.GetFileName(path);
Console.WriteLine("GetFileName('{0}') returns '{1}'",
path, result);
result = Path.GetFileName(path2);
Console.WriteLine("GetFileName('{0}') returns '{1}'",
path2, result);
This code produces output similar to the following:
GetFileName('C:\xxxx\xxxx\xxxx\abc.pdf') returns 'abc.pdf'
GetFileName('C:\xxxx\xxxx\xxxx\') returns ''
GetFileName('C:\xxxx\xxxx\xxxx') returns 'xxxx'

Sytem.IO.FileInfo is also quite cool:
In your case you can do
FileInfo fi = new FileInfo("C:\xxxx\xxxx\xxxx\abc.pdf");
string name = fi.Name; // it gives you abc.pdf
Then you can have several other pieces of information:
does the file really exist? fi.Exists gives you the answer
what's its extension? see fi.Extension
what's the name of its directory? see fi.Directory
etc.
Have a look at all the members of FileInfo you may find something interesting for your needs

Use the methods of System.IO.Path, especially Path.GetFileName.

System.IO.Path.GetFilename(yourFilename) will return the name of the file.

You could use System.IO.Path.GetFileNameWithoutExtension(string path):
System.IO.Path.GetFileNameWithoutExtension("C:\xxxx\xxxx\xxxx\abc.pdf")
And you would get back abc
