使用GroupBox

第一步：创建一个Windows窗体应用程序项目GroupBoxDemo。其窗体设计如下



第二步：计算按钮代码如下

private void button1_Click(object sender, EventArgs e)
{
       double ordinarySalary = Convert.ToDouble(textBox8.Text);  //工作日时薪
       double holidaySalary = Convert.ToDouble(textBox8.Text);  //节假日时薪

       //每天工作时间
      double monday = Convert.ToDouble(textBox1.Text);
      double tuesday= Convert.ToDouble(textBox2.Text);
      double wednesday= Convert.ToDouble(textBox3.Text);
      double thursday= Convert.ToDouble(textBox4.Text);
      double friday= Convert.ToDouble(textBox5.Text);
      double saturday= Convert.ToDouble(textBox6.Text);
      double sunday= Convert.ToDouble(textBox7.Text);

     //工作日为周一到周五，节假日为周六和周日
     double weekday = monday +tuesday+wednesday+thursday+friday;
     double holiday = saturday+sunday;

     //计算薪水并显示
     double allSalary = ordibarySalary*weekday +holidaySalary*holiday;
     textBox10.Text = allSalary.ToString();
}
     
   

double holidaySalary = Convert.ToDouble(textBox8.Text);  //节假日时薪
