Question

我可以使用PowerShell相当容易地做到这一点，但我正在寻找一种C＃方式来做到这一点。使用PS，我可以使用Get-Service迭代集合并检查名为DependentServices和RequiredServices的集合，以获取给定服务的依赖和所需服务的列表。

我使用查询“Select * from Win32_Service”查看了WMI模型，但这会返回Win32_Service个对象的集合，这些对象似乎没有我感兴趣的集合。我觉得我我在这里错过了什么。我环顾四周并尝试了各种搜索，但我没有提出一种以C＃为中心的方法。

我想查询给定的服务并获取上面提到的集合（DependentServices和RequiredServices）。对不起，如果我错过了明显的，但我真的找不到相关的主题。

您可以使用ServiceController类：

StringBuilder sb = new System.Text.StringBuilder();
foreach (var svc in System.ServiceProcess.ServiceController.GetServices())
{
    sb.AppendLine("============================");
    sb.AppendLine(svc.DisplayName);
    foreach (var dep in svc.DependentServices)
    {
        sb.AppendFormat("\t{0}", dep.DisplayName);
        sb.AppendLine();
    }
}

MessageBox.Show(sb.ToString());

您可以使用Win32_DependentService WMI类和Associators of句子来检索相关服务。

试试这个样本

using System;
using System.Collections.Generic;
using System.Management;
using System.Text;

namespace GetWMI_Info
{
    class Program
    {

        static void Main(string[] args)
        {
            try
            {
                string ComputerName = "localhost";
                ManagementScope Scope;                   
                Scope = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", ComputerName), null);

                Scope.Connect();
                ObjectQuery Query = new ObjectQuery("Associators of {Win32_Service.Name='NetMan'} Where AssocClass=Win32_DependentService ResultClass=Win32_Service");
                ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, Query);

                foreach (ManagementObject WmiObject in Searcher.Get())
                {
                    Console.WriteLine("{0,-35} {1,-40}","Name",WmiObject["Name"]);// String

                }
            }
            catch (Exception e)
            {
                Console.WriteLine(String.Format("Exception {0} Trace {1}",e.Message,e.StackTrace));
            }
            Console.WriteLine("Press Enter to exit");
            Console.Read();
        }
    }
}

您可以使用此属性 - http://msdn.microsoft.com/en-us/library/system.serviceprocess.servicecontroller.dependentservices.aspx

ServiceController sc =  new ServiceController("Event Log");
         ServiceController[] scServices = sc.DependentServices;

         // Display the list of services dependent on the Event Log service.
         if (scServices.Length == 0)
         {
            Console.WriteLine("There are no services dependent on {0}", 
                               sc.ServiceName);
         }
         else 
         {
            Console.WriteLine("Services dependent on {0}:",
                               sc.ServiceName);

            foreach (ServiceController scTemp in scServices)
            {
               Console.WriteLine(" {0}", scTemp.DisplayName);
            }
         }
