Uploading file using Post mehod to web service with XMLDocument as a parameter in C#

I am new to web service. I want to send the XML file to the web method without adding reference to webservice class, using Post method but every time i am getting 开发者_如何学CError 500 can any body help me?????

If you're using ASMX (.Net 2.0) services then you can change the webservice URL at runtime. I don't find any other reason for not adding a Web service reference.

Also for 500 Internal Server Error check whether you can access the web service.

This should solve your issue.
