c# - 有没有办法在任何未捕获的异常期间执行代码块？

Question

我意识到这是在黑暗中拍摄，而不是最佳实践或解决方法，但我想在抛出异常时做特定的日志记录信息。重要的是 Web 表单的状态不会改变。

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

如果我们在 ASP.NET 的上下文中讨论，Application_Error事件将是放置全局异常日志记录块的好地方。
