C# 连接 IBM MQ

安装 IBM WebSphere MQ：http://www-01.ibm.com/software/integration/wmq/explorer/downloads/

正确安装要注意几个地方，集群，通道发送方和通道接收方。

要想正确发送消息，必须具备以下条件：

1、传输队列。（本地队列，用法选传输）

2、消息通道（注意填写链接名称是对方IP，传输队列都填上）

3、远程队列（注意填写远程队列和远程队列管理器名称）

然后往远程队列里面填写数据，就会发送到远程的队列了！！

用C#连接IBMMQ需要引用以下几个DLL，该DLL在IBMMQ安装目录bin文件夹下！amqmdnet.dll，imqc23vn.dll，mqic32.dll，amqmdnet.dll

代码如下：

 using System.Collections.Generic;
 using System.Text;
 using IBM.WMQ.PCF;
 using IBM.WMQ;
