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]
}
}
}
