全局异常处理程序 [英] Global Exception Handler

问题描述

我编写了一个在Windows上作为批处理作业运行的控制台应用程序

2000 Server。每隔一段时间我就会向

控制台抛出异常。有没有办法可以创建一个全局处理程序，可以捕获这个

异常并阻止应用程序锁定？我在所有数据库和文件写入调用中执行尝试

catch语句，因此我不确定

来自哪里。


非常感谢任何建议或建议。


谢谢，

I have written a console application that runs as a batch job on Windows
2000 Server. Every once in a while I am getting an exception thrown to the
console. Is there a way I can create a global handler that can catch this
exception and prevent the application from locking up? I am performing try
catch statements at all database and file write calls so I am unsure where
it is coming from.

Any suggestions or recommendations are greatly appreciated.

Thanks,

Matt

推荐答案

HI，


异常是什么意思？


尝试使用AppDomain.UnHandledException和/或AppDomain.ThreadException

那是'AppDomain.UnhandledException和Application.ThreadException 。

That''s AppDomain.UnhandledException and Application.ThreadException.

Ignacio，


实际上我已经设置了这样的事件处理程序。消息是JIT调试失败，出现以下错误：0x800405a6。


文档说：

JIT调试失败，出现以下错误：0x800405a6如果您尝试此错误在没有用户登录控制台的机器上进行实时调试。因此，没有会话显示即时调试对话框。


要解决此问题，请登录计算机。


我在调度程序下运行此应用程序，所以我不确定为什么我会这样做使用此应用程序，但我的其他.Net应用程序都没有得到这个。

在main（）中我有：


AppDomain currentDomain = AppDomain.CurrentDomain;

currentDomain.UnhandledException + = new EventHandler（LastChanceHandler）;


然后方法：


void LastChanceHandler（ object sender，UnhandledExceptionEventArgs args）

{

Exception ex =（（Exception）（args.ExceptionObject））;

Logging.WriteLine（" ****** LastChanceHandler ******"）;

Logging.WriteLine（" ExceptionType：{0}"，ex.GetType（）。Name）;

Logging.WriteLine（" HelpLine：{0}"，ex.HelpLink）;

Logging.WriteLine（" Message：{0}"，ex.Message）;

Logging.WriteLine（" Source：{0}"，ex.Source）;

Logging.WriteLine（" StackTrace：{0}"，ex.StackTrace）;

Logging.WriteLine（" TargetSite：{0}"，ex.TargetSite）;

string indent ="" + Microsoft.VisualBasic.Chr（9）+"" ;;

Exception ie = ex;

while（！（（ie.InnerException == null）））{

ie = ie.InnerException;

Logging.WriteLine（缩进+" ******内部例外******"）;

Logging.WriteLine（indent +" ExceptionType：{0}"，ie.GetType（）。Name）;

Logging.WriteLine（缩进+" HelpLine：{0}"，ie.HelpLink）;

Logging.WriteLine（缩进+"消息：{0}"，ie.Message）;

Logging.WriteLine（缩进+"来源：{0}"，ie.Source）;

Logging.WriteLine（缩进+" StackTrace：{0}"，ie.StackTrace）;

Logging.WriteLine（缩进+" TargetSite：{0}"，ie.TargetSite）;

缩进+ ="" + Microsoft.VisualBasic.Chr（9）+"" ;;

}

}


关于如何捕捉错误的任何想法???


谢谢，

Ignacio,

Actually I already have an event handler set up like that. The message is JIT Debugging Failed with the following error: 0x800405a6.

Documentation says:
JIT Debugging failed with the following error: 0x800405a6This error occurs if you attempt to do Just-In-Time debugging on a machine where there is no user logged onto the console. As a result, there is no session in which to display the Just-In-Time debugging dialog box.

To fix this problem, log onto the machine.

I am running this application under the scheduler so I am unsure why I get this with this application but yet none of my other .Net applications get this.
In main() I have:

AppDomain currentDomain = AppDomain.CurrentDomain;
currentDomain.UnhandledException += new EventHandler(LastChanceHandler);

Then the method:

void LastChanceHandler(object sender, UnhandledExceptionEventArgs args)
{
Exception ex = ((Exception)(args.ExceptionObject));
Logging.WriteLine("****** LastChanceHandler ******");
Logging.WriteLine("ExceptionType: {0}", ex.GetType().Name);
Logging.WriteLine("HelpLine: {0}", ex.HelpLink);
Logging.WriteLine("Message: {0}", ex.Message);
Logging.WriteLine("Source: {0}", ex.Source);
Logging.WriteLine("StackTrace: {0}", ex.StackTrace);
Logging.WriteLine("TargetSite: {0}", ex.TargetSite);
string indent = "" + Microsoft.VisualBasic.Chr(9) + "";
Exception ie = ex;
while (!((ie.InnerException == null))) {
ie = ie.InnerException;
Logging.WriteLine(indent + "****** Inner Exception ******");
Logging.WriteLine(indent + "ExceptionType: {0}", ie.GetType().Name);
Logging.WriteLine(indent + "HelpLine: {0}", ie.HelpLink);
Logging.WriteLine(indent + "Message: {0}", ie.Message);
Logging.WriteLine(indent + "Source: {0}", ie.Source);
Logging.WriteLine(indent + "StackTrace: {0}", ie.StackTrace);
Logging.WriteLine(indent + "TargetSite: {0}", ie.TargetSite);
indent += "" + Microsoft.VisualBasic.Chr(9) + "";
}
}

Any ideas on how to capture what is wrong???

Thanks,

Matt
