MSMQ processing of a string

Here is some sample code that processes messages that are in an MSMQ queue (isn't that redundant?).  It pulls a string from a defined queue and does something with it.  Behind the scenes, it uses the threadpool to process messages in the queue.

//do a bunch of setup stuff.

//this code could be within a winforms button click, form load, or the start of a Windows Service.

gMQSearchUrl = new MessageQueue();

gMQSearchUrl.Path = gstrQueueForSearchUrl;

gMQSearchUrl.Formatter = new XmlMessageFormatter(new string[]{"System.String, mscorlib"});

gMQSearchUrl.ReceiveCompleted += new ReceiveCompletedEventHandler(this.MQ_ReceiveCompleted_ForSearchUrl );

gMQSearchUrl.BeginReceive();

private void MQ_ReceiveCompleted_ForSearchUrl(object sender, ReceiveCompletedEventArgs e)

{

      // Add code here to respond to message.

      //new XmlMessageFormatter(new String(){"System.String, mscorlib"});

      System.Messaging.Message msg = gMQSearchUrl.EndReceive(e.AsyncResult);

      msg.Formatter = new XmlMessageFormatter(new String[]{"System.String, mscorlib"});

      string strBody = (string)msg.Body;

      try

      {
