我打开了健康监控,我有以下错误,我正在努力理解:

例外:

Exception information:
    Exception type: System.InvalidCastException
    Exception message: Specified cast is not valid.


Thread information:
    Thread ID: 5
    Thread account name: NT AUTHORITY\NETWORK SERVICE
    Is impersonating: False
    Stack trace:    at _Default.Repeater1_ItemDataBound(Object sender, RepeaterItemEventArgs e)
   at System.Web.UI.WebControls.Repeater.CreateControlHierarchy(Boolean useDataSource)
   at System.Web.UI.WebControls.Repeater.OnDataBinding(EventArgs e)
   at _Default.up1_Load()
   at _Default.Timer1_Tick(Object sender, EventArgs e)
   at System.Web.UI.Timer.OnTick(EventArgs e)
   at System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument)
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

我只想弄清楚问题发生的确切位置和它是什么 - 它是在Repeater1_ItemDataBound子程序中发生的,还是在Timer1_Tick子程序中发生的？在跟踪的顶部或底部发生错误之前发生的最后一件事情是什么？

任何帮助非常感谢

谢谢
