Examples

The following example demonstrates a use of the GetFileNameWithoutExtension method.

String^ fileName = "C:\\mydir\\myfile.ext";
String^ path = "C:\\mydir\\";
String^ result;
result = Path::GetFileNameWithoutExtension( fileName );
Console::WriteLine( "GetFileNameWithoutExtension('{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:
//
// GetFileNameWithoutExtension('C:\mydir\myfile.ext') returns 'myfile'
// GetFileName('C:\mydir\') returns ''

string fileName = @"C:\mydir\myfile.ext";
string path = @"C:\mydir\";
string result;

result = Path.GetFileNameWithoutExtension(fileName);
Console.WriteLine("GetFileNameWithoutExtension('{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:
//
// GetFileNameWithoutExtension('C:\mydir\myfile.ext') returns 'myfile'
// GetFileName('C:\mydir\') returns ''

Dim fileName As String = "C:\mydir\myfile.ext"
Dim pathname As String = "C:\mydir\"
Dim result As String

result = Path.GetFileNameWithoutExtension(fileName)
Console.WriteLine("GetFileNameWithoutExtension('{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:
'
' GetFileNameWithoutExtension('C:\mydir\myfile.ext') returns 'myfile'
' GetFileName('C:\mydir\') returns ''

Remarks

This method does not verify that the path or file name exists.
