推荐答案

在理想情况下，可以使用任务并行库和任务＆LT; T＆GT; ，而不是...但除此之外，你将需要建立某种形式的共享变量的重新present的结果;当线程完成，读取任何线索，你需要它的结果。

Ideally, use the Tasks Parallel Library and Task<T> instead... but otherwise, you'll need to set up some sort of shared variable to represent the result; when the thread has finished, read the result from whatever thread you need it in.

另一种方法是使用委托返回一个布尔和呼叫的BeginInvoke 上代表就执行它线程池，返回一个的IAsyncResult ，这将让你等待结果。

Another alternative is to use a delegate which returns a bool and call BeginInvoke on that delegate to execute it on the thread-pool, returning an IAsyncResult which will allow you to wait for the result.
