2.在Web窗体中输出九九乘法表1登录事件protectedvoid Page_Load(object sender, EventArgs e) for (int i = 1; i <= 9; i+) for (int j = 1; j <= i; j+) Response.Write(i.ToString() + "*" + j.ToString() + "=" + (i * j).ToString(); Response.Write("  "); Response.Write("<br/>"); 3.输入一组以空格间隔的共10个以的整数，输出该组整数的降序排列1控件设置<%PageLanguage="C#"AutoEventWireup="true"CodeFile="ArrayDescending.asp*.cs"Inherits="E*3_ArrayDescending"%><!DOCTYPEhtml><html*mlns=".w3.org/1999/*html"><headrunat="server"><meta -equiv="Content-Type"content="te*t/html;

i <= sInput.Length - 1; i+) if (sInput.Substring(i, 1) != " ") temp += sInput.Substring(i, 1); else aInputj = int.Parse(temp); j+; temp = "0" Array.Sort(aInput);Array.Reverse(aInput);foreach (int i in aInput) if (i != 0) Response.Write(i+" "); 4.计算两个数的商1控件设置<%PageLanguage="C#"AutoEventWireup="true"CodeFile="Division.asp*.cs"Inherits="E*3_Division"%><!DOCTYPEhtml><html*mlns=".w3.org/1999/*html"><headrunat="server"><meta -equiv="Content-Type"content="te*t/html;

publicDateTime Birthday get return _Birthday; set _Birthday = value; public UserInfo(string name,DateTime birthday)this._Name = name;this._Birthday = birthday;publicstring DecideAge() if (DateTime.Now.Year - _Birthday.Year < 18) returnthis._Name + "，您还没长大呢？" else returnthis._Name + "，您是成人了！" 6.在Web窗体中应用UserInfo类1控件设置<%PageLanguage="C#"AutoEventWireup="true"CodeFile="UserInfoPage.asp*.cs"Inherits="E*3_UserInfoPage"%><!DOCTYPEhtml><html*mlns=".w3.org/1999/*html"><headrunat="server"><meta -equiv="Content-Type"content="te*t/html;

Response.Write(userInfo.DecideAge(); 7.调试九九乘法表三、习题：1.扩大成及转换程序。要求增加对输入成绩的合法性判断。protectedvoid btnSubmit_Click(object sender, EventArgs e) try float fGrade = float.Parse(t*tInput.Te*t);if (fGrade >= 0 && fGrade <= 100) int iGrade = (int)(fGrade / 10);switch (iGrade) case 10:case 9: lblDisplay.Te*t = "优秀"break;case 8: lblDisplay.Te*t = "良好"break;case 7: lblDisplay.Te*t = "中等"break;case 6: lblDisplay.Te*t = "及格"break;default: lblDisplay.Te*t = "不及格"break; else lblDisplay.Te*t = "请输入正确的成绩！" catch (E*ception ee) lblDisplay.Te*t = "不合法！" 2.将九九乘法表改成如图3-13所时的浏览效果。protectedvoid Page_Load(object sender, EventArgs e) for (int i = 1; i <= 9; i+) for (int j = i; j <= 9; j+) Response.Write(i.ToString() + "*" + j.ToString() + "=" + (i * j).ToString(); Response.Write("  "); Response.Write("<br/>"); 3.完善实验容3的程序，要求能完成包含0和负数的排序protectedvoid btnSubmit_Click(object sender, EventArgs e) string sInput = t*tInput.Te*t.Trim() + " "int j = 0;int a=0;for (int * = 0; * <= sInput.Length - 1; *+) if ( sInput.Substring(*, 1) = " ") a+; int aInput = newinta;string temp = " "for (int i = 0; i <= sInput.Length - 1; i+) if (sInput.Substring(i, 1) = "-") while (sInput.Substring(i, 1) != " ") temp += sInput.Substring(i, 1); i+; aInputj =int.Parse(temp); j+; temp = " " else if (sInput.Substring(i, 1) != " ") temp += sInput.Substring(i, 1); else aInputj = int.Parse(temp); j+; temp = " " Array.Sort(aInput);Array.Reverse(aInput);foreach (int i in aInput) if (i != 0) Response.Write(i + " "); else if (i = 0) Response.Write("0" + " "); 4.使用ArrayList类实现降序排列一组整数的功能ArrayList类：publicclassArrayListpublic ArrayList(string sInput)/ TODO: 在此处添加构造函数逻辑/this._sInput = sInput; privatestring _sInput;privateDateTime _Birthday;publicstring sInput get return _sInput;set _sInput = value; publicstring J*() int j = 0; int a = 0;for (int * = 0; * <= _sInput.Length - 1; *+) if (sInput.Substring(*, 1) = " ") a+; int aInput = newinta;string temp = " "for (int i = 0; i <= sInput.Length - 1; i+) if (sInput.Substring(i, 1) = "-") while (sInput.Substring(i, 1) != " ") temp += sInput.Substring(i, 1); i+; aInputj = int.Parse(temp); j+; temp = " " else if (sInput.Substring(i, 1) != " ") temp += sInput.Substring(i, 1); else aInputj = int.Parse(temp); j+; temp = " " Array.Sort(aInput);Array.Reverse(aInput);string s = ""foreach (int i in aInput) if (i != 0) s+=i + " " else if (i = 0) s+="0" + " " return s; 设计页面using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;publicpartialclassE*3_ArrayDescending : System.Web.UI.Pageprotectedvoid Page_Load(object sender, EventArgs e) protectedvoid btnSubmit_Click(object sender, EventArgs e) string sInput = t*tInput.Te*t.Trim() + " "ArrayList arraylist = newArrayList(sInput); Response.Write(arraylist.J*(); 6改写UserInfo类，要求如下1增加一个事件ValidateBrithday。2改写DecideAge方法，当输入的生日值大于当前日期或小于1900-1-1时触发事件ValidateBrithday3设计页面并应用修改后的UserInfo类。改写的UserInfo类：publicclassUserInfoprivatestring _Name;privateDateTime _Birthday;publicstring Name get return _Name;set _Name = value; publicDateTime Birthday get return _Birthday; set _Birthday = value; public UserInfo(string name,DateTime birthday)this._Name = name;this._Birthday = birthday;publicdelegatevoidEventHandler(object sender, EventArgs e);/声明事件所需的代理publiceventEventHandler ValidateBrithday;publicvoid OnValidateBrithday(object sender, EventArgs e) if (ValidateBrithday != null) ValidateBrithday(this, e); publicstring DecideAge() if (DateTime.Now.Year- _Birthday.Year<0| _Birthday.Year<1900) OnValidateBrithday(this, EventArgs.Empty);return" " else if (DateTime.Now.Year - _Birthday.Year < 18) returnthis._Name + "，您还没长大呢？" else returnthis._Name + "，您是成人了！" 设计页面using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;publicpartialclassE*3_UserInfoPage : System.Web.UI.Pageprotectedvoid Page_Load(object sender, EventArgs e) privatevoid V(object sender, EventArgs e) Response.Write("请输入合法的生日！"); protectedvoid btnSubmit_Click(object sender, EventArgs e) string name = t*tName.Te*t;string brithday = t*tBrithday.Te*t;UserInfo v = newUserInfo(name, DateTime.ParseE*act(brithday, "yyyyMMdd", null); v.ValidateBrithday += newUserInfo.EventHandler(V); v.DecideAge();UserInfo userInfo = newUserInfo(name,DateTime.ParseE*act(brithday,"yyyyMMdd",null); Response.Write(userInfo.DecideAge();
