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：

1. using System;

2. using System.Collections.Generic;

3. using System.ComponentModel;

4. using System.Data;

5. using System.Drawing;

6. using System.Linq;

7. using System.Text;

8. using System.Windows.Forms;

9. using System.ServiceProcess;

10.  

11. namespace 判断机器中是否安装了某项服务或者应用

12. {

13. public partial class Form1 : Form

14. {

15. public Form1()

16. {

17. InitializeComponent();

18. }

19. ServiceController[] Services = ServiceController.GetServices();

20. private bool ExistSth()

21. {

22. bool exist = false;

23. for (int i = 0; i < Services.Length; i++)

24. {

25. if (Services[i].DisplayName.ToString() == textBox1.Text.Trim())

26. exist = true;

27. }

28. return exist;

29. }

30. private void button1_Click(object sender, EventArgs e)

31. {

32. if (ExistSth())

33. MessageBox.Show("已安装");

34. else

35. MessageBox.Show("未安装");

36. }

37.  

38. private void Form1_Load(object sender, EventArgs e)

39. {

40. for (int i = 0; i < Services.Length; i++)

41. listBox1.Items.Add(Services[i].DisplayName.ToString());

42. }

43. }

44. }

       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：

1. private ServiceController _controller;

2.  

3. private void StopService()

4. {

5. this._controller = new ServiceController("ServicesName");

6. this._controller.Stop();

7. this._controller.WaitForStatus(ServiceControllerStatus.Stopped);

8. this._controller.Close();

9. }

10.  

11. private void StartService()

12. {

13. this._controller = new ServiceController("ServicesName");

14. this._controller.Start();

15. this._controller.WaitForStatus(ServiceControllerStatus.Running);

16. this._controller.Close();

17. }

18.  

19. private void ResetService()

20. {

21. this._controller = new ServiceController("ServicesName");

22. this._controller.Stop();

23. this._controller.WaitForStatus(ServiceControllerStatus.Stopped);

24. this._controller.Start();

25. this._controller.WaitForStatus(ServiceControllerStatus.Running);

26. this._controller.Close();

27. }
