应用程序调度程序和控制调度程序 [英] Application Dispatcher and Control Dispatcher

问题描述

假设我有名称为 button1的控制按钮和名称为 doSomething的功能。函数 doSomething是从另一个线程调用的。

Assume i have control button with name "button1" and function with name "doSomething". Function "doSomething" is called from another thread.

我有两种方法可以从UI线程调用函数doSomething。

i have two method to call function doSomething from UI thread.

首先，从控制按钮调度程序中

First, from control button dispatcher

this.button1.Dispatcher.BeginInvoke(new Action(() => { doSomething(); }));

其次，来自应用程序调度程序

and Second, from application dispatcher

this.Dispatcher.BeginInvoke(new Action(() => { doSomething(); }));

结果相同，真正的不同是什么？

The result is same, what is the real different ?

推荐答案

在同一线程拥有的所有控件中都引用了相同的调度程序实例。没有区别。

The same dispatcher instance is referenced in all controls owned by the same thread. There is no difference.
