推荐答案

此代码假定您已经具有带有按钮(Button1)和标签(Label1)的表单(Form1).

This code assumes that you already have a form (Form1) with a button (Button1) and a label (Label1).

public class Form1 : Form
{
    private int _studentsSoFar = 0;

    private void Button1_Click(object sender, EventArgs e)
    {
        _studentsSoFar++;
        Label1.Text = _studentsSoFar.ToString();
    }
}

然后，每次有新学生进入课程时，您都可以单击按钮.上完课后，Label1中会显示学生人数.

You can then click the button every time a new student enters the class. When class is over, the amount of students is displayed in Label1.
