Question

当我点击它并在我的活动中将其用作参数时，我想用C＃语言获取我输入的Id。

<input type="submit"  id="btn1" value ="Some Text" runat="server" onserverclick="btnClick" />

我已经搜索了很长时间寻找解决方案。

protected void btnClick(object sender, EventArgs e)
{
    // some code which use input id
}

Answer 1

您的按钮已作为参数sender传递。只需投下并进入酒店。

<input type="submit" id="btn1" value="Some Text" runat="server" onserverclick="btnClick" />

protected void btnClick(object sender, EventArgs e)
{
  var id = ((System.Web.UI.HtmlControls.HtmlInputSubmit)sender).ID;

  // 'id' now contains the value "btn1"
}

将runat服务器添加到您的输入中，然后您就可以从iCalendar iCal = new iCalendar(); Event evt = iCal.Create<Event>(); DateTime dt = (DateTime)Convert.ToDateTime(lblTicketDue.Text); Console.Write(dt); evt.Start = new iCalDateTime(dt.Year, dt.Month, dt.Day, dt.Hour, dt.Minute, dt.Second); evt.End = new iCalDateTime((DateTime)Convert.ToDateTime(lblTicketDue.Text).AddMinutes(15.0)); Alarm alarm = new Alarm(); alarm.Action = AlarmAction.Display; alarm.Summary = "Ticket due!"; Trigger t = new Trigger(); iCalDateTime icdt = new iCalDateTime(dt.Subtract(TimeSpan.FromMinutes(120.0))); t.DateTime = icdt; alarm.Trigger = t; evt.Alarms.Add(alarm); iCal.Events.Add(evt); iCalendarSerializer serializer = new iCalendarSerializer(); string output = serializer.SerializeToString(iCal); Response.ContentType = "text/calendar"; Response.Write(output); Response.End();后面的代码中访问它了

我建议使用aspx控件：

var blah = btn1.Id;

如何使用Clicked Input的Id作为c＃方法的参数
