How to use HttpWebRequest (.NET) asynchronously?

How can I use HttpWebRequest (.NET, C#) asynchronously?

Solution

  • Use HttpWebRequest.BeginGetResponse()

    HttpWebRequest webRequest;

void StartWebRequest()
{
    webRequest.BeginGetResponse(new AsyncCallback(FinishWebRequest), null);
}

void FinishWebRequest(IAsyncResult result)
{
    webRequest.EndGetResponse(result);
}

    The callback function is called when the asynchronous operation is complete. You need to at least call EndGetResponse() from this function.
