捕获完全意外的错误 [英] Catch completely unexpected error
问题描述
我有一个 ErrorRecorder 应用程序,它可以打印错误报告并询问用户是否想将该报告发送给我.
I have a ErrorRecorder App, which prints the error report out and asks if the user wants to send that report to me.
然后,我有了主应用程序.如果发生错误,它将错误报告写入文件并要求 ErrorRecorder 打开该文件以向用户显示错误报告.
Then, I have the main app. If an error occurs, It writes the error report to a file and asks ErrorRecorder to open that file to show user the error report.
因此,我使用 Try/Catch 捕获了大部分错误.
So I am catching most of my errors using Try/Catch.
但是,如果发生完全出乎意料的错误并关闭我的程序怎么办.
However, what if an error occurs that was completely unexpected and it shuts down my program.
有没有像全局/覆盖方法或类似的东西,它告诉程序如果发生意外错误,在关闭之前,调用ErrorRecorderView()"方法"
Is there like an Global/Override method or something of that kind, that tells the program "Before shutting down if an unexpected error occurs, call the "ErrorRecorderView()" Method"
推荐答案
我认为这就是您所追求的 - 您可以在应用域级别处理异常 - 即在整个程序中.

i think this is what you're after - you can handle exceptions at the appdomain level - i.e. across the whole program.
http://msdn.microsoft.com/en-GB/library/system.appdomain.unhandledexception.aspx
using System;
using System.Security.Permissions;
public class Test
{
[SecurityPermission(SecurityAction.Demand, Flags = SecurityPermissionFlag.ControlAppDomain)]
public static void Example()
{
AppDomain currentDomain = AppDomain.CurrentDomain;
currentDomain.UnhandledException += new UnhandledExceptionEventHandler(MyHandler);
try
{
throw new Exception("1");
}
catch (Exception e)
{
Console.WriteLine("Catch clause caught : " + e.Message);
}
throw new Exception("2");
// Output:
// Catch clause caught : 1
// MyHandler caught : 2
}
static void MyHandler(object sender, UnhandledExceptionEventArgs args)
{
Exception e = (Exception)args.ExceptionObject;
Console.WriteLine("MyHandler caught : " + e.Message);
}
public static void Main()
{
Example();
}
}
