我是靠谱客的博主危机外套，这篇文章主要介绍求连续数字的和------------------------------用while的算法思想，现在分享给大家，希望可以做个参考。

前端代码：

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

<!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>求连续数字的和</h2>
    <hr/>
    输入的起始数值：<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <br/>
    输入的结束数值：<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
    <br/>
        <asp:Button ID="Button" runat="server" Text="求和" οnclick="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 _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button_Click(object sender, EventArgs e)
    {
        int InStart=0;
        int InEnd = 0; 
        int Sum =0;
        InStart = int.Parse(TextBox1.Text);
        InEnd = int.Parse(TextBox2.Text);



      while(InStart<=InEnd)
      {
      Sum +=InStart;
          InStart++;
      }
      Label1.Text = Sum.ToString();
    }
}
