我想为3种排序创建3个线程（冒泡排序，快速排序和合并排序）以快速显示哪个功能排序？为了显示这个，我制作了3个按钮阵列（每个功能.1个arr）＆amp;我想用它们的高度对它们进行排序。但我有两个重要问题： 1-如何在运行时显示交换和按钮更改？排序完成后将显示表单，但我希望在运行时看到这些更改。 2-我无法使用线程一起运行排序。
这是我现在的代码：
命名空间线程 {
public partial class Form1 : Form

Button[] btns1;
Button[] btns2;
Button[] btns3;
public Form1()

btns1 =new Button[] { button1, button2, button3, button4, button5, button6, button7, button8, button9, button10, button11, button12, button13, button14, button15, button16};
btns2 = new Button[] { button17, button18, button19, button20, button21, button22, button23, button24, button25, button26, button27, button28, button29, button30, button31, button32 };
btns3 = new Button[] { button33, button34, button35, button36, button37, button38, button39, button40, button41, button42, button43, button44, button45, button46, button47, button48 };
foreach (Button btn in btns1)
{
btn.Text = btn.Size.Height.ToString();
}
foreach (Button btn in btns2)
{
btn.Text = btn.Size.Height.ToString();
}
foreach (Button btn in btns3)
{
btn.Text = btn.Size.Height.ToString();
}

}
void sort1() {
bsort(btns1, 16);
}
void sort2()
{
qsort(0, 15, btns2);
}
void sort3()
{
mgsort(0, 15, btns3);
}
Button aa = new Button(); Button aa2 = new Button();
void swap(int i,int j,Button[]btns)
{

btns[i] = btns[j];
btns[j] = aa;

btns[i].Location = new Point(btns[j].Location.X, btns[i].Location.Y);
btns[j].Location = new Point(t, btns[j].Location.Y);
}

if (btns[i].Size.Height < p)
{

return s;
}

{

qsort(l, p-1,btns);
qsort(p+1, h,btns);
}

您可以使用Control.Invoke（）发布到原始主题。
在dotnet中有几个选项可以将工作线程的计算结果传播到UI。一个是涉及返回结果，另一个是将结果发布到UI线程。
