如何从吊停止HttpClient.GetAsync（URI）？ [英] How to stop HttpClient.GetAsync(uri) from hanging?

问题描述

我有我使用调用一个URI以下code：

I have the following code that I'm using to call a uri:

var uri = string.Format("Helpers/ProfileList/Online/?locationId=0&skip=0&take={0}", numProfiles);
HttpResponseMessage response = await client.GetAsync(uri);
response.EnsureSuccessStatusCode();

URI是在自定义的Web API的URI指向（我可以调试和跟进）。然而，当在API的最后一个return语句被调用，好像没有什么改变。它应该去 response.EnsureSuccessStatus code（）; 线，但事实并非如此。它只是似乎挂。

The uri is pointing at a custom web api uri (which I can debug and follow through). However, when the last return statement in the api has been called, nothing seems to happen. It should go to the response.EnsureSuccessStatusCode(); line, but it's not. It just seems to be hanging.

推荐答案

我的蜘蛛侠，感觉告诉我，进一步您的通话堆栈的code是返回的任务阻塞，如任务.Wait 或任务＆LT; T＆GT;。结果。默认情况下，这将导致死锁，我在我的博客解释。

My spidey-sense tells me that further up your call stack your code is blocking on a returned task, e.g., Task.Wait or Task<T>.Result. By default, this will cause a deadlock that I explain on my blog.

要解决这个问题，替换 Task.Wait 和任务＆LT; T＆GT;。结果与等待。

To fix it, replace Task.Wait and Task<T>.Result with await.
