public async void MakeRequest(string requestUrl)
{
try
{
HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;
using (HttpWebResponse response = await request.GetResponseAsync() as HttpWebResponse)
{
if (response.StatusCode != HttpStatusCode.OK)
throw new Exception(string.Format(
"Server error(HTTP {0}:{1}.",
response.StatusCode,
response.StatusDescription));
DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(RootObject));
object objResponse = jsonSerializer.ReadObject(response.GetResponseStream());
root = (RootObject)objResponse;
if (root == null)
this.Frame.Navigate(typeof(MainPage));
}
}
catch (Exception ex)
{
ThrowException(ex);
}
}
我上面的代码有什么问题吗?
