c#开发windows服务

1.首先添加一个windows服务程序

2.在 protected override void OnStart(string[] args)中加入我们的业务逻辑代码

3.在我们的GateService中的设计页面，添加安装程序

4.配置安装程序serviceProcessInstaller1和serviceInstaller1

serviceInstaller1中 StartType设置为Manual，ServiceName设置为我们的服务名

serviceProcessInstaller1 中设置服务类型，Account设置为LocalService

---------------------以上我们的服务就开发完成了，但是服务不能直接启动，我们需要一个应用程序来启动我们的服务

1.建立一个winform应用程序来启动服务

2.ui页面设计四个按钮：安装、启动、停止、卸载

3.对我们的服务进行引用

4.winform代码：

using System.Collections;
using System.Collections.Generic;
using System.ComponentModel;
using System.Configuration.Install;
using System.Data;
using System.Drawing;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace GateServiceClientManager
{
    public partial class FrmClient : Form
    {
        string serviceFilePath = $"{Application.StartupPath}\\GateServiceManager.exe";//这里是我们服务的exe
        string serviceName = "GateService";
        public FrmClient()
        {
            InitializeComponent();
        }

        private void btnset_Click(object sender, EventArgs e)
