WindowsPhone8-PostJSON'；在请求正文中'；破例

Windows Phone 8-在请求正文中发布Json给出一个例外，但它正在处理“Windows控制台应用程序”。为什么会这样

例外情况： AsyncWaitHandle'（（System.Net.Browser.OHWRAsyncResult）asynchronousResult）。AsyncWaitHandle'引发了 “System.NotSupportedException”System.Threading.WaitHandle{System.NotSupportedException}类型的异常

谢谢

NotSupportedException表示Windows Phone SDK未实现该功能。异常消息将为您提供有关具体未实现的内容的更多信息

在任何情况下，我的建议都是使用System.Net.Http库，这将代码减少到大约三行

我用一台真正的设备解决了这个问题。问题在于'https'连接Windows Phone Emulator对所有请求方法的“https”链接给出了例外情况。

感谢您的建议。我试过了，但当我向HttpRequestMessage对象添加内容类型头时，出现了一些问题。添加（“授权”、“基本”+to）//ok request.Content.Headers.ContentType=new MediaTypeHeaderValue（“application/json”）；//出了问题，出了什么问题。您是否收到异常，post是否失败？请求没有采用内容类型标题，因此当调试程序跨过该行（Request.content.Headers.ContentType=new MediaTypeHeaderValue（“application/json”）；）时，请求毫无例外地失败。那么，我们如何在没有读取设备的情况下测试代码呢？
