C#启动服务

启动服务的方法有很多种，简单的cmd下dos命名，手动启动，还有C#代码启动。

我们要实现的功能：

• 判断是否安装
• 是否启动
• 启动服务
• 关闭服务

我封装了有关服务的代码，如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Threading.Tasks;

namespace windows服务
{
    public static class ServicesHelper
    {
        /// <summary>
        /// 判断是否安装了某个服务
        /// </summary>
        /// <param name="serviceName"></param>
        /// <returns></returns>
        public static bool ISWindowsServiceInstalled(string serviceName)
        {
            try
            {
                ServiceController[] services = ServiceController.GetServices();

                foreach (ServiceController service in services)
                {
                    if (service.ServiceName == serviceName)
                    {
                        return true;
                    }
                }

                return false;
            }
            catch
            { return false; }
        }

        /// <summary>
        /// 启动某个服务
        /// </summary>
        /// <param name="serviceName"></param>
        public static void StartService(string serviceName)
        {
            try
            {
                ServiceController[] services = ServiceController.GetServices();

                foreach (ServiceController service in services)
                {
                    if (service.ServiceName == serviceName)
                    {
                        service.Start();

                        service.WaitForStatus(ServiceControllerStatus.Running, new TimeSpan(, , ));
                    }
                }
            }
            catch { }
        }

        /// <summary>
        /// 停止某个服务
        /// </summary>
        /// <param name="serviceName"></param>
        public static void StopService(string serviceName)
        {
            try
            {
                ServiceController[] services = ServiceController.GetServices();

                foreach (ServiceController service in services)
                {
                    if (service.ServiceName == serviceName)
                    {
                        service.Stop();

                        service.WaitForStatus(ServiceControllerStatus.Running, new TimeSpan(, , ));
                    }
                }
            }
            catch { }
        }

        /// <summary>
        /// 判断某个服务是否启动
        /// </summary>
        /// <param name="serviceName"></param>
        public static bool ISStart(string serviceName)
        {
            bool result = true;

            try
            {
                ServiceController[] services = ServiceController.GetServices();

                foreach (ServiceController service in services)
                {
                    if (service.ServiceName == serviceName)
                    {
                        if ((service.Status == ServiceControllerStatus.Stopped)
                            || (service.Status == ServiceControllerStatus.StopPending))
                        {
                            result = false;
                        }
                    }
                }
            }
            catch { }

            return result;
        }
    }
}
