我通过设置以下env变量来解决这个问题.在连接之前.

I sloved the issue by setting following env varibles. before the connection.

环境变量是MQCHLLIB，MQCHLTAB，MQSSLKEYR-使用Environment.SetEnvironmentVariable-设置值

Env varibles are MQCHLLIB,MQCHLTAB,MQSSLKEYR - use Environment.SetEnvironmentVariable - to set values

<add key="MQ_SSL_CERT_PATH" value="D:\Cert\<nameof KDB with out .kdb>" />   
<add key="MQ_CHANNEL_LIB" value="D:\Cert" />  --- Certs location. 
<add key="MQ_CHANNEL_TAB" value="xxx.tab" />
<add key="NMQ_MQ_LIB" value="mqic.dll" />  - **Make sure you give the refarance of this DLL**

设置所有这些之后，只需调用queueManager = new MQQueueManager();即可. -你应该很好.

After setting all this just call queueManager = new MQQueueManager(); - You should be good.
