相当于InvokeRequired在WPF [英] Equivalent to InvokeRequired in WPF

问题描述

有一个相当于Form.InvokeRequired在WPF中，例如？Dispatcher.InvokeRequired

Is there an equivalent to Form.InvokeRequired in WPF, e.g. Dispatcher.InvokeRequired?

推荐答案

，因为它不会出现在智能感知，但你可以使用这是有点奇怪：

This is slightly odd as it doesn't appear in intellisense, but you can use:

var dispatcher = myDispatcherObject.Dispatcher;
if (dispatcher.CheckAccess()) { /* ... */ }

由于所有UI组件从 DispatcherObject的继承这个应该解决您的具体问题，但它不是具体到UI线程 - 它可以被用于任何调度

As all UI components inherit from DispatcherObject this should solve your specific problem, but it is not specific to the UI thread - it can be used for any dispatcher.
