Hi,

You can use string array and split options to get the file name.

I hope hte following code will satisfy ur needs

(e.g.)

string strPath = @"C:\some_folder\somefile.txt";

string[] strFileParts = strPath.Split( '\\' ); [ Use Single Quotes ]

if ( strFileParts.Length > 0 )

{

MessageBox.Show ( " The file name is "

+ strFileParts[strFileParts.Length - 1] );

}

Regards,
Krishnakumar
