Out of curiosity, why aren't you using .NET's snazzy powerful Web Services features?

If you're consuming someone else's Web Service, you may do the following:

1. In the designer, right-click your project and select "Add Web Reference".

2. Enter the URL of the service you want to consume. The dialog should display information about the available services if all goes well.

3. Select the service you want and OK your way out of the dialogs (or whatever).

VS.NET will then create proxy classes to handle all of the plumbing for the Web Services. Once you reach this point, you can instantiate the Service as an object, and treat it like you would any other class (making method calls, getting return values, etc). Microsoft made it pretty user friendly!

This tutorial will explain more:

Hi boulderBam
You see what i want is not that much easy i know how i can call a web-service at the Net but my problem is that the web-site i am trying to connect is a JAVA refferer so i need to submit packet of information to that site with a client certificate used for authentication with the above code i can hit some other web-sites which is non-secure but when i am trying to connect to the secure web-site its giving me that error.

Could it be as simple as the account the cope runs under not having access to the certificate on the local machine?
