Random String Generation in ASP.Net

/*  Random Password Using RNG  */

                //Method1 Using RNG Crypto Service Provider

                byte[] saltpass = new byte[4];

                RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider();

                rng.GetBytes(saltpass);

                test = Convert.ToBase64String(saltpass);

                test = test.Remove(test.Length - 3, 3);//This is for removing last 3 chatcters from random string

                //Method2 using Get Random file name it will creates a file name with .tmp extension so replace with null after .(dot) and the default Length of file is 11 with out extension

                string outpass = Path.GetRandomFileName();

                outpass = outpass.Replace(".", ""); // Remove period.

                outpass = outpass.Remove(outpass.Length - 3, 3);
