Unable to cast MSMQ body to an object

[Bill Wright]

Hi,

I built an assembly with a class, NodeBuildCommand, in the namespace
"Tendril". I use that assembly on one computer to send a
NodeBuildCommand object in the body of a System.Messaging.Message.
This works without error. On the receiving computer I use the same
assembly and then try to cast the body to that object. When this
happens I get a "Type not found error" from GetType(), which is called
from the get_Body() method on the System.Messaging.Message object.

In the development environment on the remote computer in the Immediate
window of the debugger I can do the following:

(new Tendril.NodeBuildCommand()).GetType().Name = "NodeBuildCommand"

(new Tendril.NodeBuildCommand()).GetType().Namespace = "Tendril"

so why doesn't this work:

System.Type.GetType("Tendril.NodeBuildCommand")

This last line returns null and this is the source of my problem with
the casting. Any ideas on how to proceed?

Thanks,
Bill

You need to beomce famaliar with the formatter argument
System.Messaging.IMessageFormatter


Here is smoe sample code:

public class MyMSMQListener
{

MessageQueue _queue = null;
public MyMSMQListener(string queuePath ,
System.Messaging.IMessageFormatter formatter, int receiveOrPeekMilliSeconds)
{
this.ConstructorCommon(queuePath , receiveOrPeekMilliSeconds);
this._queue.Formatter = formatter; // Customize the formatter type
}

private void ConstructorCommon(string queuePath , int
receiveOrPeekMilliSeconds)
{

Console.WriteLine("MyMSMQListenerwas constructed");

this._queue = new MessageQueue(queuePath);

this.m_receiveOrPeekMilliSeconds = receiveOrPeekMilliSeconds;

}

}
