wp8 dll 中如何使用 xmlhttprequest2 ?
正在把win store dll 的代码转到win phone dll中,
其中Windows::Storage::Streams::InMemoryRandomAccessStream类不支持wp8，
应该如何改写，才能获取一个stream ,然后能通过xmlhttprequest2.send发给出去？
windows store中的代码：
ComPtr<IStream> sequentStream;
auto randomAccessStream = ref new Windows::Storage::Streams::InMemoryRandomAccessStream();
CreateStreamOverRandomAccessStream(randomAccessStream, IID_PPV_ARGS(&sequentStream));
...
sequentStream->Write(aDst, strlen(aDst), NULL);
ret = m_xhr->Send(sequentStream.Get(), strlen(aDst)+1);
