HTTP request post and get call interface and reflection dynamic call WebServices class

This code is the API, websrvices dynamic invocation of the class, make the interface call is very useful.

WebServices Dynamic invocation of the use of reflection is a big drawback is inefficient, if there is a better dynamic call webservices method, I hope you do not hesitate to paste the code.
