C#使用ServiceController控制windows服务

    C#中，使用ServiceController类控制windows服务，使用之前要先添加引用：System.ServiceProcess，然后在命名空间中引用：using System.ServiceProcess。下面举例获取本机的所有已安装的Windows服务和应用，然后查找某一应用活服务是否已经安装。

代码：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.ServiceProcess;

namespace 判断机器中是否安装了某项服务或者应用
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        ServiceController[] Services = ServiceController.GetServices();
        private bool ExistSth()
        {
            bool exist = false;
            for (int i = 0; i < Services.Length; i++)
            {
                if (Services[i].DisplayName.ToString() == textBox1.Text.Trim())
                    exist = true;  
            }
            return exist;
        }
        private void button1_Click(object sender, EventArgs e)
        {
            if (ExistSth())
                MessageBox.Show("已安装");
            else
                MessageBox.Show("未安装");
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            for (int i = 0; i < Services.Length; i++)
                listBox1.Items.Add(Services[i].DisplayName.ToString());
        }
    }
}

       假设某一服务名为ServicesName, 编写开始服务,停止服务,重启服务的代码如下：

private ServiceController _controller;

private void StopService()
{
    this._controller = new ServiceController("ServicesName");
    this._controller.Stop();
    this._controller.WaitForStatus(ServiceControllerStatus.Stopped);
    this._controller.Close();
}

private void StartService()
{
    this._controller = new ServiceController("ServicesName");
    this._controller.Start();
    this._controller.WaitForStatus(ServiceControllerStatus.Running);
    this._controller.Close();
}

private void ResetService()
{
    this._controller = new ServiceController("ServicesName");
    this._controller.Stop();
    this._controller.WaitForStatus(ServiceControllerStatus.Stopped);
    this._controller.Start();
    this._controller.WaitForStatus(ServiceControllerStatus.Running);
    this._controller.Close();
}
