C#,MySQL,ADO.NET,分隔符导致语法错误

一个.sql文件基本如下：

DROP PROCEDURE IF EXISTS myProc;

DELIMITER $$

CREATE PROCEDURE myProc()
BEGIN
-- procedure stuff goes here
END $$

DELIMITER ;

CALL myProc();

当我将它输入到MySQL查询浏览器的脚本窗口时,它会一遍又一遍地运行,就像人们希望的那样.

但是,如果我将字符串放入我的IDbCommand并执行它…

connection.Open(); // An IDbConnection
IDbTransaction transaction = connection.BeginTransaction();
using (IDbCommand cmd = connection.CreateCommand())
{
    cmd.Connection = connection;
    cmd.Transaction = transaction;
    cmd.CommandText = line;
    cmd.CommandType = CommandType.Text;

    try
    {
        cmd.ExecuteNonQuery();
    }
    catch (SqlException ex)
    {
        transaction.Rollback();
        return false;
    }
}

transaction.Commit();
connection.Close();

……我得到了可怕的例外1064 ……

You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near ‘DELIMITER $$CREATE PROCEDURE myProc() BEGIN…

所以,问题是……为什么MySQL让我这样做没有问题,但是当我尝试从C#运行它时,它失败了？当然第二个问题是我应该如何修复它.
