how can i make an infinite loop with 5 second pauses
===

        
        string connectionstring = "server =SQLVS2\\SQLVS2;database=DDM;Persist Security Info=True;uid=ddmuser;password=User02+Ddm;";
        SqlConnection myConnection = new SqlConnection(connectionstring);
        SqlCommand myCommand = new SqlCommand("GetNullHash", myConnection);
        myCommand.CommandType = CommandType.StoredProcedure;
        myConnection.Open();
        SqlDataReader rdr = myCommand.ExecuteReader();
        
       while (rdr.Read())
        {
            string filename = @"\\" + rdr.GetString(3);
            filename = System.IO.Path.Combine(filename, rdr.GetString(2));
            filename = System.IO.Path.Combine(filename, rdr.GetString(1));
            computeHashh1 abc = new computeHashh1();
            Console.WriteLine(abc.computeHash(filename));          
            inserthash insert = new inserthash();
           insert.InsertHash(rdr.GetString(1), abc.computeHash(filename), rdr.GetStr(2),rdr.GetString(3));
       
        }
how can i make this loop run once in 5 seconds for ever or untill stopped.
