我必须等待异步方法吗? [英] Do I have to await an async method?

问题描述

我使用仅支持异步方法的HttpClient.

I use a HttpClient that only supports async methods. Do I have to await them in the calling method (not in the async method itself, I have to await the calls in HttpClient methods as far as I know)?

在那个项目中我真的不需要多线程.我会很好地阻止并等待直到收到HttpClient的响应，因为无论如何我都需要数据.这是一个Console应用程序.

I don't really need multithreading in that project. I would be fine blocking and waiting until I get a response from HttpClient as I need to have the data anyway. This is a Console application.

推荐答案

否，不需要任何操作来await通话.该呼叫只是将Task<T>返回给您，而不是直接返回T.如果在Task上调用Result属性:

No, nothing requires you to await the call. The call is just returning a Task<T> to you, rather than a T directly. If you call the Result property on the Task:

var result = client.MakeCallAsync().Result;

您正在告诉它我不在乎它是否阻塞，我希望我的代码(和该线程)在这里等待直到完成."

You are telling it "I don't care if it blocks, I want my code (and this thread) to wait here till this is done."
