Js代码

window.setTimeout("window.location.href='Default5.aspx?timestamp="+Date.parse(new Date())+"'",1000);

window.setTimeout("window.location.href='Default5.aspx?timestamp="+Date.parse(new Date())+"'",1000);

2:

Html代码

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default5.aspx.cs" Inherits="Default5" %>

<!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>

<script type="text/javascript">

setTimeout("document.getElementById(\"Button1\").click()",3000);

</script>

</head>

<body>

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

<div>

<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" style="display:none;" />

</div>

</form>

</body>

</html>

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default5.aspx.cs" Inherits="Default5" %>    <!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>      <script type="text/javascript">          setTimeout("document.getElementById(\"Button1\").click()",3000);      </script>  </head>  <body>      <form id="form1" runat="server">      <div>          <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" style="display:none;" />      </div>      </form>  </body>  </html>

后台:

C#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 Default5 : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void Button1_Click(object sender, EventArgs e)

{

Response.Write(DateTime.Now);

}

}

using System;  using System.Collections.Generic;  using System.Linq;  using System.Web;  using System.Web.UI;  using System.Web.UI.WebControls;    public partial class Default5 : System.Web.UI.Page  {      protected void Page_Load(object sender, EventArgs e)      {        }      protected void Button1_Click(object sender, EventArgs e)      {          Response.Write(DateTime.Now);      }  }

3:

C#代码

Response.AddHeader("refresh","10;url=Default5.aspx");

Response.AddHeader("refresh","10;url=Default5.aspx");

4:

Html代码

<meta http-equiv="refresh" content="3;url=Default5.aspx" />        <meta http-equiv="refresh" content="3" /><!--如果不知道那个URL则默认为当前页-->

5:

C#代码

StringBuilder script = new StringBuilder();

script.Append("<script type=\"text/javascript\">\n");

script.Append("window.setInterval('postme()',3000)\n");

script.Append("function postme(){\n");

script.Append("document.forms[0].submit();\n");

script.Append("}\n");

script.Append("</script>\n");

Page.ClientScript.RegisterStartupScript(this.GetType(),"refresh",script.ToString());

StringBuilder script = new StringBuilder();              script.Append("<script type=\"text/javascript\">\n");              script.Append("window.setInterval('postme()',3000)\n");              script.Append("function postme(){\n");              script.Append("document.forms[0].submit();\n");              script.Append("}\n");              script.Append("</script>\n");              Page.ClientScript.RegisterStartupScript(this.GetType(),"refresh",script.ToString());

6:将刷新时间放到配置文件里:

Html代码

<meta http-equiv="refresh" content="<%= System.Configuration.ConfigurationManager.AppSettings["test"].ToString() %>" />

Xml代码

<add key="test" value="3"/>

上面这六种方式都是B/S模式下的页面刷新，那么在C/S模式下怎么实现呢？今天这个问题难为了我多半天时间，现在终于琢磨出来了，分享给大家：

1、添加一个

控件
2、

其Interval根据你的需要设置刷新时间间隔，此处设置3秒。
3、

在事件中，Tick设置需要刷新的代码事件。
