C# 封装：Windows 服务的安装、启停与状态查询

在 C# 开发中，对 Windows 服务进行生命周期管理往往涉及大量重复的 API 调用。为了简化运维脚本或后台管理程序的编写，这里整理了一套工具类，涵盖了服务的安装卸载、启停控制、状态检测及版本获取等核心功能。

前置条件

确保项目已添加以下命名空间引用，并具备管理员权限（部分操作如安装服务需要）：

using System;
using System.Configuration.Install;
using System.IO;
using System.Reflection;
using System.ServiceProcess;
using Microsoft.Win32;

枚举定义

为了统一返回的服务状态，我们定义一个本地枚举，避免直接暴露 ServiceControllerStatus 的复杂性：

public enum ServiceStatus
{
    CannotGet,
    Stopped,
    StartPending,
    Running,
    StopPending,
    PausePending,
    Paused,
    ContinuePending
}

核心工具类

以下是完整的静态方法实现，建议将其保存为 WindowsServiceHelper.cs 以便复用。

服务信息查询

获取服务安装路径时，需从注册表读取 ImagePath 值。注意处理空引号的情况，否则路径解析会出错。

/// <summary>
/// 获取服务安装路径
/// </summary>
public static string GetWindowsServiceInstallPath(string serviceName)
{
    string key = @"SYSTEM\CurrentControlSet\Services\" + serviceName;
    using (var subKey = Registry.LocalMachine.OpenSubKey(key))
    {
        if (subKey == null) return string.Empty;
        
        var path = subKey.GetValue("ImagePath").ToString();
        
        path = path.Replace(, .Empty);
        
         fi =  FileInfo(path);
         fi.Directory.ToString() + ;
    }
}





{
     services = ServiceController.GetServices();
     ( s  services)
    {
         (s.ServiceName.ToLower() == nameService.ToLower())
             ;
    }
     ;
}





{
    ServiceStatus status = ServiceStatus.CannotGet;
     scs = ServiceController.GetServices();
    
     ( sc  scs)
    {
         (serviceName.ToUpper() == sc.ServiceName.ToUpper())
        {
             (sc.Status)
            {
                 ServiceControllerStatus.Stopped: status = ServiceStatus.Stopped; ;
                 ServiceControllerStatus.StartPending: status = ServiceStatus.StartPending; ;
                 ServiceControllerStatus.Running: status = ServiceStatus.Running; ;
                 ServiceControllerStatus.StopPending: status = ServiceStatus.StopPending; ;
                 ServiceControllerStatus.PausePending: status = ServiceStatus.PausePending; ;
                 ServiceControllerStatus.Paused: status = ServiceStatus.Paused; ;
                 ServiceControllerStatus.ContinuePending: status = ServiceStatus.ContinuePending; ;
            }
            ;
        }
    }
     status;
}





{
     (.IsNullOrEmpty(serviceName))  .Empty;
    
    
    {
         path = GetWindowsServiceInstallPath(serviceName) +  + serviceName + ;
         assembly = Assembly.LoadFile(path);
         version = assembly.GetName().Version;
         version.ToString();
    }
     (Exception ex)
    {
        Console.WriteLine(); 
         .Empty;
    }
}
