计算机科学与技术学院实验报告（电子版）课程： .NET程序设计 实验名称结构化程序设计语句指导老师耿卫江姓 名学 号班 级实验地点实验日期成绩一、实验内容：1.?设计一个简单的Windows应用程序，在文本框中两个点的坐标值，单击“确定”时显示两点之间的距离。2.?自定义一个时间类。该类包含小时、分、秒字段与属性，具有将秒增加1秒的方法。二、实验目的： 1.掌握方法及构造函数的定义。 2.掌握调用方法及形参与实参的对应关系。 3.掌握“值传递”和“地址传递”的传递方式。三、涉及实验的相关情况介绍（包含使用软件或实验设备等情况）：安装Microsoft Visual Studio 的计算机四、程序清单与测试数据：第一题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 lab5_1_{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { double x = 0, z = 0, s = 0; Double x1 = Convert.ToDouble(textBox1.Text); Double y1 = Convert.ToDouble(textBox3.Text); Double x2 = Convert.ToDouble(textBox2.Text); Double y2 = Convert.ToDouble(textBox4.Text); distance dis = new distance(x1, y1, x2, y2); x = dis.resout(); z = dis.resout1(); s = Math.Sqrt(x + z); label6.Text = 两点之间的距离为： + s; } public class distance { public Double m = 0; public Double n = 0; public Double x1; public Double y1; public Double x2; public Double y2; public distance(Double x1, Double y1, Double x2, Double y2) { this.x1 = x1; this.x2 = x2; this.y1 = y1; this.y2 = y2; } public Double resout() { return m = Math.Pow(x2 - x1, 2); } public Double resout1() { return n = Math.Pow(y2 - y1, 2); } } }}第二题、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 lab5_2_{ public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { time t = new time(); textBox1.Text = t.ShowHour(); textBox2.Text = t.ShowMinute(); textBox3.Text = t.ShowSecond(); } public class time { public int hour, minute, second; public time() { hour = System.DateTime.Now.Hour; minute = System.DateTime.Now.Minute; second =
