C# 重新启动后，我的Windows服务无法启动

我可以手动成功启动/停止服务，但在系统重新启动时无法启动，尽管启动类型设置为

“自动”

。在某些终端上，重新启动时，服务无法启动，出现错误

无法连接DB

在调试开发环境时，我甚至没有收到任何错误。假设在我的机器上，firebird服务确实在我的服务启动之前启动，但它仍然无法在重新启动时启动服务。日志里什么都没有

我在代码中添加了一些日志点，当我手动停止/启动服务时，它们都会被记录下来。但当系统重新启动且服务器从未启动时，日志中不会显示任何内容

尝试将Firebird服务作为依赖项添加到项目/服务安装程序中，设置

DelayedAutoStart=true

。无论我在网上读到什么解决方案，我都尝试过，但服务并没有在重启时启动

下面我将添加服务的起始点/入口点片段

Program.cs

MyService.cs

        TransactionLogManager.WriteServiceLogInfo("Started");
        eventLog1.WriteEntry("Started.");
    }

}

ProjectInstaller-包括

System.ServiceProcess.ServiceProcessInstaller

和

System.ServiceProcess.ServiceInstaller

private System.ServiceProcess.ServiceProcessInstaller serviceProcessInstaller1;
private System.ServiceProcess.ServiceInstaller serviceInstaller1;
private MyService myService ;

private void InitializeComponent()
{
    this.serviceProcessInstaller1 = new System.ServiceProcess.ServiceProcessInstaller();
    this.serviceInstaller1 = new System.ServiceProcess.ServiceInstaller();
    this.myService = new IntegrationService.MyService();

    // serviceProcessInstaller1
    this.serviceProcessInstaller1.Account = System.ServiceProcess.ServiceAccount.LocalSystem;
    this.serviceProcessInstaller1.Password = null;
    this.serviceProcessInstaller1.Username = null;

    // serviceInstaller1
    this.serviceInstaller1.Description = "My Integration Service";
    this.serviceInstaller1.DisplayName = "MyService";
    this.serviceInstaller1.ServiceName = "MyService";
    //this.serviceInstaller1.ServicesDependedOn = new string[] { "Firebird Guardian - DefaultInstance", "Firebird Server - DefaultInstance" };
    //this.serviceInstaller1.DelayedAutoStart = true;
    this.serviceInstaller1.StartType = System.ServiceProcess.ServiceStartMode.Automatic;

    // myService 
    this.myService.ExitCode = 0;
    this.myService.ServiceName = "MyService";

    // ProjectInstaller
    this.Installers.AddRange(new System.Configuration.Install.Installer[] {
    this.serviceProcessInstaller1,
    this.serviceInstaller1});
}

日志点-在手动启动/停止时，我会得到以下日志点，但当我重新启动系统时，不会出现任何问题

事件日志中是否有任何内容？每当Windows不启动服务时，它都应该在事件日志中记录。你检查过事件查看器了吗？考虑将启动类型设置为<代码>自动（延迟启动）< /代码>。也不要考虑在<代码> OnStutter（）/代码>方法中连接到数据库，事件日志中除了在代码中写入的条目之外没有任何东西，并且当我手动启动服务时，这些条目只出现在事件日志中。重新启动时，事件日志中不会显示任何内容。@chadnt我也尝试过延迟启动，显然它对我的同事起作用，但对我的系统不起作用。关于在OnStart中避免DB连接，我会尝试让你们知道，但我想知道尝试连接DB是否有问题，那么为什么我的日志点都没有被记录下来。它甚至不记录

Program.cs

中

Main（）

方法中的内容。这是否意味着服务根本没有启动，或者只是在一开始就失败了？事件日志中是否有任何内容？当Windows不启动服务时，它应该在事件日志中做一个记录。你检查过事件查看器了吗？考虑将启动类型设置为<代码>自动（延迟启动）< /代码>。也不要考虑在<代码> OnStutter（）/代码>方法中连接到数据库，事件日志中除了在代码中写入的条目之外没有任何东西，并且当我手动启动服务时，这些条目只出现在事件日志中。重新启动时，事件日志中不会显示任何内容。@chadnt我也尝试过延迟启动，显然它对我的同事起作用，但对我的系统不起作用。关于在OnStart中避免DB连接，我会尝试让你们知道，但我想知道尝试连接DB是否有问题，那么为什么我的日志点都没有被记录下来。它甚至不记录
