C# 擷取windows services相關資訊

要加入對System.Management的reference的引用。下面是程式的介面圖：

 

下面是代碼對照著很容易看懂：

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.Management;using System.Collections;namespace WinFormService{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        ArrayList arrServices = new ArrayList();        private void Form1_Load(object sender, EventArgs e)        {            // Create a new ManagementClass object binded to the Win32_Service WMI class            ManagementClass mcServices = new ManagementClass("Win32_Service");                        // Loop through each service            foreach (ManagementObject moService in mcServices.GetInstances())            {                // Create a new array that holds the ListBox item ID and service name                string[] srvArray = new string[2];                srvArray[0] = lstServices.Items.Add(moService.GetPropertyValue("Caption").ToString()).ToString();                srvArray[1] = moService.GetPropertyValue("Name").ToString();                // Store the array in the ArrayList                arrServices.Add(srvArray);            }        }        private void lstServices_SelectedIndexChanged(object sender, EventArgs e)        {            ManagementClass mcServices = new ManagementClass("Win32_Service");            // Loop through each service            foreach (ManagementObject moService in mcServices.GetInstances())            {                // Get back the array with the index of the selected ListBox item from the ArrayList                string[] srvArray = (string[])arrServices[lstServices.SelectedIndex];                // If the current service name                if (moService.GetPropertyValue("Name").ToString() == srvArray[1])                {                    // Set the fields accordingly                    txtDesc.Text = moService.GetPropertyValue("Description").ToString();                    lblPath.Text = "Path: " + moService.GetPropertyValue("PathName");                    lblType.Text = "Type: " + moService.GetPropertyValue("ServiceType");                    lblState.Text = "State:  " + moService.GetPropertyValue("State");                    lblStartup.Text = "Start-up Type:  " + moService.GetPropertyValue("StartMode");                }            }        }    }}

 

處理2個事件，一個是FormLoad 還有一個就是List的selectIndexchanged事件。
