I hope you have Client Attach Facility on z/OS or you are not going to get very far.

Are you connecting to to the z/OS queue manager or is the z/OS queue manger tranmiting the messages to a Windoze Qmgr?

Queue is on mainframe.

I am able to put my own messages on the queue and get them and read them.

I am able to check the various properties on the queue and the message.

Just the msg.ReadString() method dies.

Here is the line that raises the MQException:
Logger.Log(MqsMsg.ReadString(MqsMsg.MessageLength));

Logger is part of our framework. String is the parameter.

Well, have you considered all the possibilities including a null value?

The length of the message is 1285.
DataLength = 1285.
MessageLength= 1285.
TotalMessageLength = 1285.

Tring different encoding, I get back garbled characters.

byte[] msgbytes = new byte[MqsMsg.MessageLength];
MqsMsg.ReadFully(ref msgbytes);
MsgContents = enc.GetString(msgbytes);
