如何运行循环异步，因此它不会挂起UI [英] How to run for loop async so it doesn't hang the UI

问题描述

我正在使用bing地图导航API来绘制行车路线。我需要使用for循环来获得lat long路径。现在，当我输入长路径时，for循环挂起UI，因为它必须循环超过大限制，那么我怎么能停止挂起UI呢？我尝试了
使用Dispatcher.RunAsync（）但没有工作，也尝试过Task.Run（）但它抛出错误"应用程序调用了一个为不同线程编组的接口"。我需要更好的解决方案，所以它循环并绘制路线。

Hi, I am using bing map navigation API to draw driving route. I need to use for loop for getting the lat long of route. Now the for loop hangs the UI when I enter the long route as it has to loop over large limit, so how can I stop hanging the UI ? I tried using Dispatcher.RunAsync() but not working, also tried Task.Run() but it throws error "The application called an interface that was marshalled for a different thread". I need better solution so it loops through and draw the route.
