C＃记录点击之间的时间

Question

我在C＃中有代码，用于在运行时记录时间和鼠标光标坐标。我想要它做的是在点击一个正方形（nextTaskBttn_Click）和一个圆圈之间花时间。 （TestForm_MouseClick）所以我希望它记录时间然后减去以获得点击之间的时间。我不确定这样做的最佳或正确方法是什么。有人有什么建议吗？

这是代码：

namespace FittsLawExperiment
{
    public partial class TestForm : Form
    {
        private Random r = new Random();
        private int Count = 0;
        private String fileData = String.Empty;
        private List<SizeDistanceDirectionClass> myList = new List<SizeDistanceDirectionClass>();
        Point globalPoint = new Point();
        int globalDiameter = 0;
        //int globalPointX = 0; test
        //int globalPointY = 0;

    public TestForm()
    {
        InitializeComponent();

        FormBorderStyle = FormBorderStyle.None;
        WindowState = FormWindowState.Normal;//change to Maximize

        //variables for size, distance and direction
        int s1 = 30;
        int s2 = 50;
        int s3 = 70;
        int d1 = 50;
        int d2 = 100;
        int l = 0;
        int r = 1;
        //set into groups of three into temps
        SizeDistanceDirectionClass temp1 = new SizeDistanceDirectionClass(s1, d1, l);
        SizeDistanceDirectionClass temp2 = new SizeDistanceDirectionClass(s2, d1, l);
        SizeDistanceDirectionClass temp3 = new SizeDistanceDirectionClass(s3, d1, l);
        SizeDistanceDirectionClass temp4 = new SizeDistanceDirectionClass(s1, d2, l);
        SizeDistanceDirectionClass temp5 = new SizeDistanceDirectionClass(s2, d2, l);
        SizeDistanceDirectionClass temp6 = new SizeDistanceDirectionClass(s3, d2, l);
        SizeDistanceDirectionClass temp7 = new SizeDistanceDirectionClass(s1, d1, r);
        SizeDistanceDirectionClass temp8 = new SizeDistanceDirectionClass(s2, d1, r);
        SizeDistanceDirectionClass temp9 = new SizeDistanceDirectionClass(s3, d1, r);
        SizeDistanceDirectionClass temp10 = new SizeDistanceDirectionClass(s1, d2, r);
        SizeDistanceDirectionClass temp11 = new SizeDistanceDirectionClass(s2, d2, r);
        SizeDistanceDirectionClass temp12 = new SizeDistanceDirectionClass(s3, d2, r);

        myList.Add(temp1);//added to myList
        myList.Add(temp2);
        myList.Add(temp3);
        myList.Add(temp4);
        myList.Add(temp5);
        myList.Add(temp6);
        myList.Add(temp7);
        myList.Add(temp8);
        myList.Add(temp9);
        myList.Add(temp10);
        myList.Add(temp11);
        myList.Add(temp12);
    }

在.NET中，已经存在一个完全相同的类：StopWatch。
