如何在Windows Phone Silverlight项目中创建http Web请求？

Question

I want to make an Http Post and get response from Windows Phone App...Here is how I would have done it in ASP.net.

string strUrl =  "http://....."; 
WebRequest request = HttpWebRequest.Create(strUrl);
HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
Stream s = (Stream)response.GetResponseStream();
StreamReader readStream = new StreamReader( s );
string dataString = readStream.ReadToEnd();
response.Close();
s.Close();
readStream.Close();

But I cannot do this as it gives an error that GetResponse method cannot be Used in Silverlight Project. What is an alternative to this and how do I do it?

Most methods that cause blocking behaviour have been eliminated from the WP/Silverlight APIs (the idea here is not to give the developer any opportunity to inadvertently lock up the UI).

Synchronous IO falls into this category.

You need to rewrite your method using async methods:

public async Task<SomeReturnType> MyMethod()
{
    //...
    HttpWebResponse response = 
        (HttpWebResponse)(await request.GetResponseAsync()); 
    //...

}
