从任务获取HttpResponseMessage<；HttpResponseMessage>；

在HttpClient内部使用语句，我需要从某处打开HttpResponseMessage。

using (HttpClient client = new HttpClient())
{
     client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", authUser);
     Task<HttpResponseMessage> m = client.GetAsync(url);   
     // HttpResponseMessage msg = ???              
     task.Wait();
     return task.Result;
}

我的问题是：如何从这一行获取HttpResponseMessage

Task<HttpResponseMessage> m = client.GetAsync(url);

从任务获取HttpResponseMessage<；HttpResponseMessage>；

您应该await任务：

HttpResponseMessage m = await client.GetAsync(url);

为此，需要将调用方法标记为async。

要获得HttpResponseMessasge，您应该使用Task.Result属性。以下是您的代码（有点修改），其中HttpResponseMessage来自任务：

using (HttpClient client = new HttpClient())
{
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", authUser);
    Task<HttpResponseMessage> task = client.GetAsync(uri);
    **HttpResponseMessage msg = task.Result;**
    task.Wait();
    return task.Result;
}
