您好我想基于一个时间跨度调用方法
这是我的踪迹
protected void binddata(object sender,EventArgs e) { //我的逻辑在这里 }
现在我想每隔5分钟调用一次这个方法
使用c#和asp.net我怎样才能实现这个目标?
谢谢

使用System.Threading.Timer - http://msdn.microsoft.com/en-us/library/system.threading.timer.aspx。

你在ASP.Net ajax控件中有一个计时器控件 http://msdn.microsoft.com/fr-fr/library/system.web.ui.timer.aspx
它提供了postbak
例如来自msdn:
<%@ Page Language="C#" AutoEventWireup="true" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html >
<head runat="server">
<title>Timer Example Page</title>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
OriginalTime.Text = DateTime.Now.ToLongTimeString();
}
protected void Timer1_Tick(object sender, EventArgs e)
{
StockPrice.Text = GetStockPrice();
TimeOfPrice.Text = DateTime.Now.ToLongTimeString();
}
private string GetStockPrice()
{
double randomStockPrice = 50 + new Random().NextDouble();
return randomStockPrice.ToString("C");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:Timer ID="Timer1" OnTick="Timer1_Tick" runat="server" Interval="10000" />
<asp:UpdatePanel ID="StockPricePanel" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" />
</Triggers>
<ContentTemplate>
Stock price is <asp:Label id="StockPrice" runat="server"></asp:Label><BR />
as of <asp:Label id="TimeOfPrice" runat="server"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
<div>
Page originally created at <asp:Label ID="OriginalTime" runat="server"></asp:Label>
</div>
</form>
</body>
</html>
希望得到这个帮助。

Timer myTimer = new Timer();
myTimer.Elapsed += new ElapsedEventHandler( binddata);
myTimer.Interval = 5*60*100;
myTimer.Start();
