示例：

using System

using System.Collections.Generic

using System.ComponentModel

using System.Data

using System.Drawing

using System.Linq

using System.Text

using System.Windows.Forms

namespace test

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent()

}

enum WeekDay { 星期天,星期一,星期二,星期三,星期四,星期五,星期六}

private void button1_Click(object sender, EventArgs e)

{

DateTime dt = Convert .ToDateTime ( textBox1 .Text)

label1.Text = "\n这一天是" + dt.DayOfWeek

WeekDay wd =(WeekDay ) dt.DayOfWeek

label1.Text+= "（即′："+wd +")"

}

}

}

扩展资料

设计一个简单的Windows程序，输入5个数字，然后排序并输出；

using System

using System.Collections.Generic

using System.ComponentModel

using System.Data

using System.Drawing

using System.Linq

using System.Text

using System.Windows.Forms

namespace bb

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent()

}

int[]a=new int[5]

int i = 0

private void button1_Click(object sender, EventArgs e)

{

if (i <5)

{

a[i] = Convert.ToInt32(textBox1.Text)

label2.Text += Convert .ToString( a[i])+"  "

i++

textBox1.Text = ""

}

}

private void Form1_Load(object sender, EventArgs e)

{

label2.Text = "排序前的数字序列："

}

private void button2_Click(object sender, EventArgs e)

{

Array.Sort(a)

label2.Text += "\n排序后的数字序列："+a[0]+" "+a[1]+" "+a[2]+" "+a[3]+" "+a[4]

}

}

}
