问题描述
我想有在后台线程，创建为它未来的变种，再后来要求的计算值一样简单做了一些工作。
I'd like to have some work done in a background thread as simple as creating a Future var for it and then asking later for the calculated value.
在伪C＃-code：
AsyncFuture<int> asyncFuture = new AsyncFuture<int>(FuncToCalculateValue);
//do some other work, or draw UI
if(asyncFuture.NoErrorsHappened){
int realResult = asyncResult.Value;
}
我可以通过我自己的实现这样的类型，但我的问题是：不是个吨，有些种类的已知图案的？是否有可能一个名字，或者甚至是一个框架的实施？大概在.NET 4.0？
I can implement such type by my own, but my question is: isn't that some kind of a known pattern? Is there maybe a name for it, or maybe even a framework implementation? Probably in .NET 4.0?
而如果它是一个模式，什么是与它相关的陷阱？
And if it is a pattern, what are the pitfalls associated with it?
推荐答案
Yacoder，我真的很喜欢的的。有一些 rel=\"nofollow\">对利弊的意见。
Yacoder, I really like Ayende's two Future implementations. There is some good discussion from Jon Skeet in the comments on the cons.
这篇关于" AsyncFuture< T>"或者是什么？未来< T>在后台线程获得的 - 它是一个模式？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
