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);
}
