基于IBM MQ的.net开发遇到的头疼问题
背景：MQClient 对接MQServer服务器都是server2003，只开通了1314端口进行访问。对方IT说没有开通pin功能，但是可以对联。
开始报2035 没有权限的异常。发现对方MCA标示没有设置，并且对方不愿意修改，说是成型的系统，有很多人在用。
最后头疼了好长时间，在一位前和他们对接过系统的公司的人那里找到了解决方法，在系统中创建一个对方指定的用户。
用此用户登录。（为此用户设置mqm权限）
不知道是否MQ服务器安装的时候都应该指定MCA用户标示，是否不设定的情况下更好的理由？
另从IBM扒的代码参数传递的时候用hashtable的方法传参数，看起来不错，记下来。
