Path.GetRandomFileName Method

Note: This method is new in the .NET Framework version 2.0.

Returns a random folder name or file name.

Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)

public static string GetRandomFileName ()
public static String GetRandomFileName ()
public static function GetRandomFileName () : String

Return Value

A random folder name or file name.

The GetRandomFileName method returns a cryptographically strong, random string that can be used as either a folder name or a file name. Unlike GetTempFileName, GetRandomFileName does not create a file. When the security of your file system is paramount, this method should be used instead of GetTempFileName.
