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

public static string GetRandomFileName()

Return Value

Type: System.String

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.

The following example show output from the GetRandomFileName method.

using System;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string result = Path.GetRandomFileName();
            Console.WriteLine("Random file name is " + result);
        }
    }
}

/*

 This code produces output similar to the following:
