使用C#设计几个简单有趣的WinForm程序

在Visual Studio 2015中，新建winform新项目。开始编写窗体程序。

简易计算器

如下图设计好winform程序，然后双击相应的控件进行代码的编写。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
        InitializeComponent(); 
        }
        private void button2_Click(object sender, EventArgs e)
        { 
        	int x1, x2;
            string st = "";
            x1 = int.Parse(textBox1.Text);
            x2 = int.Parse(textBox2.Text);
            st = st + "x1+x2=" + (x1 + x2) + "\n";
            st = st + "x1-x2=" + (x1 - x2) + "\n";
            st = st + "x1*x2=" + (x1 * x2) + "\n";
            st = st + "x1/x2=" + (x1 / x2) + "\n";
            st = st + "int的最大值是：" + (int.MaxValue.ToString()) + "\n";
            label3.Text = st; 
        }
        private void button1_Click(object sender, EventArgs e)
        {
        	textBox1.Clear();
            textBox2.Clear();
            label3.Text = "";
            textBox1.Focus();
        } 
    }
}

        { 
         	if (radioButton1.Checked == true)
                label1.Text = DateTime.Now.Year + "年" + DateTime.Now.Month + "月" + DateTime.Now.Day + "日";
            if (radioButton2.Checked == true)
                label1.Text = DateTime.Now.Hour + "时" + DateTime.Now.Minute + "分" + DateTime.Now.Second + "秒"; 
         }
        private void button2_Click(object sender, EventArgs e)
        { 
        	Application.Exit(); 
        } 
    }
 }
