这段代码演示在 C# 程序中调用 MySQL 的存储过程，没有返回值，没有参数传递。

MySqlConnection myConnection;          myConnection = new MySqlConnection();  myConnection.ConnectionString = "database="+database+";server="+      server+";user id="+user+";Password="+password;  try  {      myConnection.Open();  }  catch (MySqlException MyException)            {      Console.WriteLine("Connection error: MySQL code: "+          MyException.Number +" "+           MyException.Message);  }    try {       MySqlCommand myCommand = new MySqlCommand(      "call error_test_proc(1)",          myConnection     );                 myCommand.ExecuteNonQuery();  }  catch (MySqlException MyException)            {     Console.WriteLine("Stored procedure error: MySQL code: " +               MyException.Number + "  " +               MyException.Message);  }
