我们利用ASP.NET来实现简单的注册界面

## 一：注册首页的界面代码（.aspx文件 这里使用的是asp自带的控件，也可以使用HTML的控件来实现） ##

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Register.aspx.cs" Inherits="Web.Register" %>
    
    
    <!DOCTYPE html>
    
    
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
        <title>用户注册</title>
    </head>
    <body>
                 
        <asp:Label ID="Label1" runat="server" Text="用户注册"></asp:Label>
        <form id="form1" runat="server">
        <div>
                    
            <br />
            <br />
        </div>
            用户名：<asp:TextBox ID="TextBoxName" runat="server"></asp:TextBox>
            <br />
            <br />
     密码： <asp:TextBox ID="TextBoxPassword" runat="server" TextMode="Password"></asp:TextBox>
            <br />
            <br />
            <br />
     性别：<br />
            <asp:RadioButtonList ID="RadioButtonListSex" runat="server" RepeatDirection="Horizontal">
                <asp:ListItem Value="male">男</asp:ListItem>
                <asp:ListItem Value="female">女</asp:ListItem>
            </asp:RadioButtonList>
            <br />
            <br />
            职业：<br />
            <asp:RadioButtonList ID="RadioButtonListWork" runat="server" RepeatDirection="Horizontal">
                <asp:ListItem Value="publicServat">公务员</asp:ListItem>
                <asp:ListItem Value="doctor">医务工作者</asp:ListItem>
                <asp:ListItem Value="teacher">教师</asp:ListItem>
                <asp:ListItem Value="business">经商</asp:ListItem>
            </asp:RadioButtonList>
            <br />
            所属省份：<asp:DropDownList ID="DropDownListProvince" runat="server" AutoPostBack="True" OnSelectedIndexChanged="DropDownListProvince_SelectedIndexChanged" style="height: 19px">
                <asp:ListItem Value="guangdong">广东省</asp:ListItem>
                <asp:ListItem Value="guangxi">广西省</asp:ListItem>
                <asp:ListItem Value="heilongjiang">黑龙江省</asp:ListItem>
            </asp:DropDownList>
            <br />
            <br />
            所在城市：<asp:ListBox ID="ListBoxCity" runat="server" Height="43px" style="margin-top: 4px" Width="102px"></asp:ListBox>
            <br />
            <br />
            爱好：<asp:CheckBoxList ID="CheckBoxListHobby" runat="server" RepeatColumns="2">
                <asp:ListItem>球类运动</asp:ListItem>
                <asp:ListItem>田径运动</asp:ListItem>
                <asp:ListItem>读书看报</asp:ListItem>
                <asp:ListItem>聊天交友</asp:ListItem>
            </asp:CheckBoxList>
            <br />
           
            <asp:Button ID="ButtonOk" runat="server" OnClick="ButtonOk_Click" Text="确定" />
            <br />
        </form>
    </body>
    </html>

## 二：后台处理代码（C\#实现 .aspx.cs） ##

using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Web.UI;
    using System.Web.UI.WebControls;
    
    
    namespace Web
    {
        public partial class Register : System.Web.UI.Page
        {
            protected void Page_Load(object sender, EventArgs e)
            {
    
    
            }
    
    
            protected void DropDownListProvince_SelectedIndexChanged(object sender, EventArgs e)
            {
                switch (DropDownListProvince.SelectedItem.Text)
                {
                    case "广东省":
                        ListBoxCity.Items.Clear();
                        ListBoxCity.Items.Add("广州市");
                        ListBoxCity.Items.Add("深圳市");
                        break;
                    case "广西省":
                        ListBoxCity.Items.Clear();
                        ListBoxCity.Items.Add("南宁市");
                        ListBoxCity.Items.Add("桂林市");
                        break;
                    case "黑龙江省":
                        ListBoxCity.Items.Clear();
                        ListBoxCity.Items.Add("哈尔滨市");
                        ListBoxCity.Items.Add("齐齐哈尔市");
                        break;
    
    
                }
            }
    
    
            protected void ButtonOk_Click(object sender, EventArgs e)
            {
                string name, password, sex = " ", work, location = "", hobby = "";
                if (TextBoxName.Text == "")
                {
                    Response.Write("<script>window.alert('用户名不能为空！');</script>");
                }
                else
                {
                    name = TextBoxName.Text;
                    password = TextBoxPassword.Text;
                    if (RadioButtonListSex.Items[0].Selected)
                    {
                        sex = "男";
                    }
                    else if (RadioButtonListSex.Items[1].Selected)
                    {
                        sex = "女";
                    }
                    work = RadioButtonListWork.SelectedItem.Text;
                    if (ListBoxCity.SelectedItem != null)
                    {
                        location = DropDownListProvince.SelectedItem.Text + "," + ListBoxCity.SelectedItem.Text;
                    }
                    for (int i = 0; i < CheckBoxListHobby.Items.Count; i++)
                    {
                        if (CheckBoxListHobby.Items[i].Selected)
                            hobby += CheckBoxListHobby.Items[i].Text + ",";
                    }
                    hobby = hobby.TrimEnd(',');
                    Response.Redirect(string.Format("SimpleResult.aspx?name={0}&sex={1}&work={2}&location={3}&hobby={4}", name, sex, work, location, hobby));
                }
            }
        }
    }

## 三：结果界面代码（ .aspx文件） ##

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="SimpleResult.aspx.cs" Inherits="Web.SimpleResult" %>
    
    
    <!DOCTYPE html>
    
    
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
        <title>注册信息</title>
    </head>
    <body>
        <form id="form1" runat="server">
        <div>
        您注册的信息是：<br />
            姓    名：<%=name %><br />
            性    别：<%=sex %><br />

            请牢记你的密码！
        </div>
        </form>
    </body>
    </html>

                 hobby = Request.QueryString["hobby"];
            }
        }
    }
