c# - Dispatcher线程和UI线程有什么区别

Question

UI 线程和 Dispatcher 线程在 WPF 中是一样的还是有什么区别？

Answer 1

A Dispatcher负责管理线程的工作。

UI线程是渲染UI的线程。

The UI thread queues work items inside an object called a Dispatcher. The Dispatcher selects work items on a priority basis and runs each one to completion. Every UI thread must have at least one Dispatcher, and each Dispatcher can execute work items in exactly one thread.
