问题描述
我有不同的情况下,比,因此另外一个问题。
I have different scenario, than in this question, therefore another question.
让我们以下面的例子:
void PerformanceCriticalMethod()
{
Dispatcher.Invoke(() => Log.Add("1"));
... some job
Dispatcher.Invoke(() => Log.Add("2"));
}
调用
创建性能问题。在试图解决它,我在调用
,它的似乎工作的中使用 InvokeAsync
,但它是什么 2
将输出的是非常重要的后 1
。
Invoke
creates performance problems. In attempt to fix it I used InvokeAsync
in place of Invoke
and it seems to work, but it is important what 2
will be output after 1
.
我可以依靠的假设,如果两个 InvokeAsync
从他们将以相同的顺序执行同一个线程叫什么? 。为链接我的一个的 WINAPI的螺母的告诉我,这是真的,但我想肯定
Can I rely on assumption what if two InvokeAsync
are called from same thread they will execute in the same order? My winapi's nut tells me it's true, but I want to be sure.
和另外一个相关的问题是一样的:如果同样的方法从不同的线程通过 InvokeAsync
被称为动作,多么好机会,有它第一次执行线程谁调用 InvokeAsync
更早?
And another related question is same as linked one: if same method is called via InvokeAsync
action from different threads, how good are chances to have it executed first for thread who calls InvokeAsync
earlier?
PS:我觉得问题应该被改写InvokeAsync如何工作,但秩序可能是什么人(包括我在内)100%的候选人将尝试搜索。
P.S.: I have feeling question should be rephrased "How InvokeAsync works", but the word "order" is probably 100% candidate of what people (including me) will try to search for.
推荐答案
请,检查了这一点的
当你调用InvokeAsync,操作放置到PriorityQueue的,所以我想,如果你调用优先级相同的几个动作,你可以相信,这些行动将用相同的顺序来执行。
When you call InvokeAsync, an operation is put to PriorityQueue, so I suppose if you call several actions with the same priority, you can be confident that these actions will be executed with the same order.
