如何在Windows Event Viewer中删除和创建日志 [英] How to remove and create log in Windows Event Viewer

问题描述

我有一个应用.我试图在Windows Event Viewer崩溃时写日志.我发现写入Windows应用程序事件日志，并且我正在使用DispatcherUnhandledExceptionEventHandler捕获未处理的异常.我在应用的构造函数中设置它，例如:

I have an app. I'm trying to write log in Windows Event Viewer when its crashing. I found Write to Windows Application Event Log and I'm using DispatcherUnhandledExceptionEventHandler for catching unhandled exception. I'm setting it in constructor of app like:

 DispatcherUnhandledException += MyApplication_DispatcherUnhandledException;

并这样写日志:

using (EventLog eventLog = new EventLog("Application"))
        {
            eventLog.Source = "Application";
            eventLog.WriteEntry(exceptionMessage, EventLogEntryType.Error);
        }

创建日志，但在System.Windows.Application的Run方法中发生另一个异常，并且Windows在事件查看器中使用另一个ID，源代码添加了此错误.

Log creates, but in Run method of System.Windows.Application occurs another exception and windows adds this error in Event Viewer with another Id, source....

Description: The process was terminated due to an unhandled exception.

异常信息:System.Exception 在ServerApp.MainWindow..ctor()

Exception Info: System.Exception at ServerApp.MainWindow..ctor()

异常信息:System.Windows.Markup.XamlParseException 在System.Windows.Markup.WpfXamlLoader.Load(System.Xaml.XamlReader，System.Xaml.IXamlObjectWriterFactory，布尔值，System.Object，System.Xaml.XamlObjectWriterSettings，System.Uri)中 在System.Windows.Markup.WpfXamlLoader.LoadBaml(System.Xaml.XamlReader，布尔值，System.Object，System.Xaml.Permissions.XamlAccessLevel，System.Uri) 在System.Windows.Markup.XamlReader.LoadBaml(System.IO.Stream，System.Windows.Markup.ParserContext，System.Object，布尔值) 在System.Windows.Application.LoadBamlStreamWithSyncInfo(System.IO.Stream，System.Windows.Markup.ParserContext) 在System.Windows.Application.LoadComponent(System.Uri，布尔值) 在System.Windows.Application.DoStartup()

Exception Info: System.Windows.Markup.XamlParseException at System.Windows.Markup.WpfXamlLoader.Load(System.Xaml.XamlReader, System.Xaml.IXamlObjectWriterFactory, Boolean, System.Object, System.Xaml.XamlObjectWriterSettings, System.Uri) at System.Windows.Markup.WpfXamlLoader.LoadBaml(System.Xaml.XamlReader, Boolean, System.Object, System.Xaml.Permissions.XamlAccessLevel, System.Uri) at System.Windows.Markup.XamlReader.LoadBaml(System.IO.Stream, System.Windows.Markup.ParserContext, System.Object, Boolean) at System.Windows.Application.LoadBamlStreamWithSyncInfo(System.IO.Stream, System.Windows.Markup.ParserContext) at System.Windows.Application.LoadComponent(System.Uri, Boolean) at System.Windows.Application.DoStartup()

如何只写我的登录事件查看器?

How can I write only my log in event viewer?

推荐答案

using System;
using System.Diagnostics;

...
...

public void WriteToEventLog(EventLogEntryType eventLogType, string message, string logSourceName)
{
    if (!EventLog.SourceExists(logSourceName))
    {
        EventLog.CreateEventSource(logSourceName, "Application");
    }
    using (var eventLog = new EventLog { Source = logSourceName })
    {
        const int maxLength = 31000;
        if (message.Length > maxLength)
        {
            message = message.Substring(0, maxLength);
        }
        eventLog.WriteEntry(message, eventLogType);
    }
}

要使用此应用程序运行帐户的用户必须具有访问权限才能创建日志.

The user, under which account this app is going to run, needs to have access to be able to create logs.

祝你好运.
