有沒有辦法在任何未捕獲的異常期間執行代碼塊？

Question

我意識到這是一個黑暗的鏡頭，而不是最佳實踐或解決方法，但是我想做特定的日志記錄信息，因為會拋出異常。 Web表單的狀態不要更改，這一點很重要。

Answer 1

You can use 

    try
    {

    }
    catch(Exception ex)
    {
      //your treatment does not contain throw ex.
      //mute exception in order to not change state
    }

You can use this in your webform or in your gloabl.asax in Application_Error (in order to centralize exception treatment)

Answer 2

try
{
    ExceptionProneCode()
}
catch(Exception ex)
{
    WriteToSomeLogFile(ex.Message);

    //if you want the exception to bubble up from this point, 
    //than you would type "throw;"
}

Answer 3

如果我們在ASP.NET上下文中進行交談，則Application_Error事件將是放置全局異常日志記錄塊的好地方。
