顯示運行時間和線程上的表格變化

Question

我想創建3個線程進行3種排序（冒泡排序，快速排序&合併排序）以快速顯示哪種函數排序？爲了顯示這個我做了3個按鈕陣列（對於每個func。1 arr）&我想用它們的高度對它們進行排序。但我有2個重要問題： 1-如何在運行時顯示交換和按鈕更改？該表單將在排序完成後顯示，但我希望在運行時看到這些更改。我不能和線程一起運行排序併發。

現在這是我的代碼：

Answer 1

你可以使用Control.Invoke（）張貼到原來的線程。

在dotnet中有幾個選項可將計算結果從工作線程傳播到UI。一個會涉及返回結果，另一個會將結果發佈到UI線程。
