Question

在我的WPF应用程序中，我需要获取具有特定属性的Windows服务（~200）列表。

while (current($List) !== $Current) next($List);
    echo next($List);

执行此方法大约需要1分钟，并返回不可接受的数据。看起来像searcher.Get（）需要所有的时间...... 我可以做些什么来改善执行/返回时间/性能？

根据我提出的评论，希望它可以帮助某人：

 public List<string> GetWindowsServicesList()
    {
        var result = new List<string>();
        foreach (ServiceController service in ServiceController.GetServices())
        {
            string serviceName = service.ServiceName;
            result.Add(serviceName);
        }
        return result;
    }

    public ServicesModel GetServiceProperties(string serviceName)
    {
        ServicesModel service = null;
        string path = $"Win32_Service.Name=\"{serviceName}\"";

        using (ManagementObject mngObj = new ManagementObject(path))
        {
            service = new ServicesModel
            {
                Name = mngObj.GetPropertyValue("Name") as string,
                Path = mngObj.GetPropertyValue("PathName") as string,
                Description = mngObj.GetPropertyValue("Description") as string,
                Pid = Convert.ToInt32(mngObj.GetPropertyValue("ProcessId")),
                Status = mngObj.GetPropertyValue("State") as string,
                StartMode = mngObj.GetPropertyValue("StartMode") as string,
                LogOnAs = mngObj.GetPropertyValue("StartName") as string
            };
        }
        return service;
    }

    public List<ServicesModel> WindowsServicesCollection()
    {
        var result = new List<ServicesModel>();
        try
        {
            var windowsServicesNames = GetWindowsServicesList();

            for (int i = 0; i < windowsServicesNames.Count(); i++)
            {
                result.Add(GetServiceProperties(windowsServicesNames[i]));
            }
        }
        catch (System.Management.ManagementException ex)
        {
        }
        catch (System.TimeoutException ex)
        {
        }
        return result;
    }

比以前的解决方案工作得多，速度快得多，虽然看起来性能不是非常一致，而且取决于我没有发现的各种因素......
