Hi Erdinc Here is one c3 code that i got from c-sharpcorner!! /// /// Generates a random string with the given length /// /// Size of the string /// If true generate lowercase string /// Random string private string RandomString( int size bool lowerCase) { StringBuilder builder = new StringBuilder(); Random random = new Random(); char ch ; for ( int i=0; i { ch = Convert.ToChar(Convert.ToInt32(Math.Floor(26 * random.NextDouble() + 65))) ; builder.Append(ch); } if (lowerCase) return builder.ToString().ToLower(); return builder.ToString(); } -shinu
