求约束------------------------ do while循环 算法思想

前段代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

    <title></title>

</head>

<body>

    <form id="form1" runat="server">

    <div>

     <h2>求2到200之间任意一个数的约数</h2>

   <br/>

    输入任意一个数字：<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

    <br/>

        <asp:Button ID="Button" runat="server" Text="取余" onclick="Button_Click" />

        <br/>

        <asp:Label ID="Label1" runat="server" Text=""></asp:Label>

    </div>

    </form>

</body>

</html>

　　后端代码：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

public partial class Default2 : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {

    }

    protected void Button_Click(object sender, EventArgs e)

    {

        int yueshu;

        int i=1;

        string temp = "";

        yueshu = int.Parse(TextBox1.Text);

        do

        {

            if (yueshu % i == 0)

            {

               temp += " "+i;

            }

            i++;

        } while (i<=yueshu);

        Label1.Text = temp;

    }

}
