Silverlight、C#：Post in HttpWebRequest

以下主要在從事Silverlight做Web Request，以Post對Server要求資料時用上：

　WebClient wc_DoLogin = new WebClient();
wc_DoLogin.UploadStringCompleted += new
　　　UploadStringCompletedEventHandler(wc_DoLogin_UploadStringCompleted);
　wc_DoLogin.Headers["content-type"]
　　　= "application/x-www-form-urlencoded";
　wc_DoLogin.UploadStringAsync(
　　new Uri(Url, UriKind.Absolute),
　　"POST",
　　"欄位１=欄位值&欄位２=欄位值２");

Server回應將會在wc_DoLogin_UploadStringCompleted被接收：

void wc_DoLogin_UploadStringCompleted
(object sender, UploadStringCompletedEventArgs e)
{
MessageBox.Show("result is : " + e.Result);
}
