C# 安装使用Topshelf制作的Windows服务时添加参数

我一直在学习如何使用Topshelf在C#中创建windows服务。 该服务工作正常，但我在安装时添加自己的参数时遇到一些问题

安装时，我希望为该服务提供一个connectionstring（

connStr

），以后需要使用它。现在，该服务只需将“connectionstring是…”写入文本文件，以进行测试

下面是我的代码，我使用Topshelf将我的“ServiceClass”转换为windows服务。 “ServiceClass”在其构造函数中获取connectionstring

我已经添加了很多次行

Console.WriteLine（“调试器…”）

，这样我就可以看到安装时发生了什么

当我使用命令提示符安装服务时，程序似乎“忘记”了我在“ServiceClass”的构造函数中给它的字符串

如您所见，“DEBUGGER”0-5行都以正确的顺序出现，并且具有正确的“connStr”值。 然而，由于某种原因，“调试器1”被再次调用，我不明白为什么

有人知道我做错了什么吗

当我在调试模式下（使用命令行参数）运行与控制台应用程序相同的程序时，一切正常

static void Main(string[] args)
        {
            string connStr = null;  //ConnectionString
            Console.WriteLine("DEBUGGER 0");

            var exitCode = HostFactory.Run(x =>
            {
                x.AddCommandLineDefinition("connStr", f =>
                {
                    connStr = f;
                    Console.WriteLine("DEBUGGER 1,  connStr = " + f);
                });
                x.ApplyCommandLine();

                Console.WriteLine("DEBUGGER 2");

                x.Service<ServiceClass>(s =>
                {
                    s.ConstructUsing(sc => new ServiceClass(connStr));
                    s.WhenStarted(sc => sc.Start());
                    s.WhenStopped(sc => sc.Stop());
                    Console.WriteLine("DEBUGGER 3");
                });

                //Service-properties
                x.RunAsLocalSystem();
                x.SetDisplayName("Loader Service");
                x.SetServiceName("LoaderService");
                x.SetDescription("Some description");
                x.StartAutomatically();

                Console.WriteLine("DEBUGGER 4");

                x.BeforeInstall(() => { });
                x.AfterInstall(() => { });
                x.BeforeUninstall(() => { });
                x.AfterUninstall(() => { });

                Console.WriteLine("DEBUGGER 5");

            });

            int exitCodeValue = (int)Convert.ChangeType(exitCode, exitCode.GetTypeCode());
            Environment.ExitCode = exitCodeValue;

        }
