Method
Definition
Returns the file name and extension of the specified path string.
public static string GetFileName (string path);
- path
- String
The path string from which to obtain the file name and extension.
The characters after the last directory character in path. If the last character of path is a directory or volume separator character, this method returns Empty. If path is null, this method returns null.

Examples
The following code example demonstrates the behavior of the GetFileName method on a Windows-based desktop platform.
String^ fileName = "C:\\mydir\\myfile.ext";
String^ path = "C:\\mydir\\";
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 );
// This code produces output similar to the following:
//
// GetFileName('C:\mydir\myfile.ext') returns 'myfile.ext'
// GetFileName('C:\mydir\') returns ''
string fileName = @"C:\mydir\myfile.ext";
string path = @"C:\mydir\";
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);
// This code produces output similar to the following:
//
// GetFileName('C:\mydir\myfile.ext') returns 'myfile.ext'
// GetFileName('C:\mydir\') returns ''
Dim fileName As String = "C:\mydir\myfile.ext"
Dim pathname As String = "C:\mydir\"
Dim result As String
result = Path.GetFileName(fileName)
Console.WriteLine("GetFileName('{0}') returns '{1}'", fileName, result)
result = Path.GetFileName(pathname)
Console.WriteLine("GetFileName('{0}') returns '{1}'", pathname, result)
' This code produces output similar to the following:
'
' GetFileName('C:\mydir\myfile.ext') returns 'myfile.ext'
' GetFileName('C:\mydir\') returns ''
Remarks
The returned value is null if the file path is null.
The separator characters used to determine the start of the file name are DirectorySeparatorChar and AltDirectorySeparatorChar.
