SqlConnection myConnection = new SqlConnection(connString);

try
{
   myConnection.Open();
   string query = "insert into Customer(CustomerName,CustomerAddress,PhoneNo) values (@CustNm,'@CustAdd',@Ph)";
   SqlCommand myCommand = new SqlCommand(query,myConnection);
   myCommand.Parameters.AddWithValue("CustNm",Print[0].CustomerName);
   myCommand.Parameters.AddWithValue("CustAdd",Print[0].Address);
   myCommand.Parameters.AddWithValue("Ph",Print[0].Telephone);

   Console.WriteLine(Print[0].Telephone);
