问题描述
我彻底整糊涂等待在C＃/异步模式。
I'm thoroughly confused by the whole await / async pattern in C#.
我有一个表格应用程序，我想调用了一个20秒的方法做一吨的处理。因此，我想的await 它。我认为正确的方法是将其标记为异步任务但是这样做会产生警告，因为我不使用的await 内的任何地方。
I have a forms app, and I want to call a method that takes 20 seconds to do a ton of processing. Therefore I want to await it. I thought the correct way was to mark it as async Task but doing this produces a warning because I don't use await anywhere within it.
一个谷歌透露一些关于返回 TaskCompletionSource< T> ，但我没有返回类型，因为它是无效的。
A google revealed something about returning a TaskCompletionSource<T> but I don't have a return type, since it's void.
我怎么能说用这种方法等待？
How can I call this method using await?
推荐答案
打电话给你的方法如下：
Call your method as following:
await Task.Run(() => YourMethod());
当你使用它为您创建一个awaitable任务Task.Run方法。
When you use the Task.Run method it creates an awaitable task for you.
