According to the requirements of the landlord, with my own writing of the HttpClient class, the code is written as follows, but because there is no test account, so the test using the account and password for test , the return of the result is landing failure, landlord only need to modify the code in the account and password, should be able to.
HTTPThe request process is Cookie HttpClient/CURL handled automatically by the.

The code of the landlord should be no problem, the feeling should be not submitted RadioButtonList1 and Button1 the two data.
And that __VIEWSTATE although it seems to be fixed, but for insurance period, or should be obtained from the page after, and then submit the landing.
