Creating XLang Message using C#

Question

Hello all,
I want to create a new XLangMessage using C# code to test one of the method which takes XLangMessage as input.
Here is what i tried:
Microsoft.XLANGs.BaseTypes.
XLANGMessage sampleOutput;
XmlDocument tempInput=new XmlDocument ();
tempInput.Load (
@"InputMessage.xml");
sampleOutput[0].LoadFrom(tempInput.ToString());
returnOutput = classObject.MethodName (sampleOutput
In the method i implemented some logic.
However am getting an error message : "Use of Unassigned valriable".
I tried by initializing null. In that case, its throwing error, "Object Ref Not Set To An Instance" at [sampleOutput[0].LoadForm()] line.
How to proceed further?
Regards
kumaraguru

I don't know why you need to create XlangMessage (I do do this occasionally, but not very often), and I strongly suggest that you read Paolo Salvatori's excellent post -

It will be very useful for you (and any BizTalk developer!) in general, the last section about custom BTX message shows how you can create and return an XlangMessage if you have to.
Well worth while looking at the second part of this post as well - http://blogs.msdn.com/b/paolos/archive/2009/09/21/4-different-ways-to-process-an-xlangmessage-within-an-helper-component-invoked-by-an-orchestration-part-2.aspx
