C＃窗口服务能否自动登录到自定义事件源/日志

Question

我有一个C＃窗口服务，我正在其中创建ng-template文件中的自定义事件源和日志名称，

ProjectInstaller.Designer.cs

，当我安装窗口服务时，日志名称显示在private void InitializeComponent() { this.serviceProcessInstaller1 = new System.ServiceProcess.ServiceProcessInstaller(); this.serviceInstaller1 = new System.ServiceProcess.ServiceInstaller(); // // serviceProcessInstaller1 // this.serviceProcessInstaller1.Account = System.ServiceProcess.ServiceAccount.LocalSystem; this.serviceProcessInstaller1.Password = null; this.serviceProcessInstaller1.Username = null; // // serviceInstaller1 // this.serviceInstaller1.ServiceName = "DemoService"; this.serviceInstaller1.StartType = System.ServiceProcess.ServiceStartMode.Automatic; var eventLog1 = new System.Diagnostics.EventLog(); if (!System.Diagnostics.EventLog.SourceExists("MySource")) { System.Diagnostics.EventLog.CreateEventSource( "MySource", "MyNewLog"); } eventLog1.Source = "MySource"; eventLog1.Log = "MyNewLog"; // // ProjectInstaller // this.Installers.AddRange(new System.Configuration.Install.Installer[] { this.serviceProcessInstaller1, this.serviceInstaller1}); } 下，

现在，服务中所有未处理的异常是否都将以源'MySource`记录在Applications and Service Logs下？

MyNewLog

当前它在protected override void OnStart(string[] args) { throw new NotImplementedException(); } 下记录，来源为“ Service1”

好，配置EventLog到类构造函数中：

void InitiateEventLog(EventLog eventLog)
{
    if (!EventLog.SourceExists("MySource"))
    {
       EventLog.CreateEventSource("MySource", "MyNewLog");
    }
    eventLog.Source = "MySource";
    eventLog.Log = "MyNewLog";
}

您的构造函数应类似于：

public Service1()
{
    InitiateEventLog(EventLog);
    InitializeComponent();
}

然后，您可以使用OnStart方法捕获未处理的异常，然后编写 CUSTOM 日志：

    protected override void OnStart(string[] args)
    {
        AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
    }

    private void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
    {
        EventLog.WriteEntry($"Unhundeled Exception occurred: {(e.ExceptionObject as Exception).Message}");
    }
