如何在 C# 中使用 WMI 查询从 UWF 获取注册表和文件排除项

问题描述

我想使用 WMI 从 UWF 获取所有注册表排除和文件排除.

I want to get all registry exclusion and file exclusion from UWF, using the WMI.

我已经尝试从 UWF_RegistryFilter 类调用 GetExclusions 方法，但没有成功.

I've already tried to invoke GetExclusions methods from UWF_RegistryFilter class but of no luck.

我期待一个有效的示例代码，提前感谢您的帮助！

I am looking forward to a working sample code, thanks in advance for any help!

推荐答案

难点是从方法结果中读取出参数.Microsoft 网站 很难猜测如何使用 ManagementBaseObject 来读取输出参数.

The difficult part is to read the out parameters from the method result. There is no appropriate documentation available on Microsoft website and it's difficult to guess how ManagementBaseObject can be utilized for reading the out parameters.

为了找到解决方案，我尝试根据其他有据可查的 wmi 示例了解 WMI 如何利用 out 参数.请使用下面的C#代码，希望对您有所帮助:

In order to reach to a solution, I tried to develop an understanding of how WMI makes use of out parameters based on other well-documented wmi samples. Please use the C# code below, I hope it helps:

public static void GetRegistryExclusions()
    {

        ManagementScope scope = new ManagementScope(@"rootstandardcimv2embedded");
        using (ManagementClass mc = new ManagementClass(scope.Path.Path, "UWF_RegistryFilter",
        null))
        {
            ManagementObjectCollection moc = mc.GetInstances();
            foreach (ManagementObject mo in moc)
            {
                ManagementBaseObject[] result = (ManagementBaseObject[])mo.InvokeMethod("GetExclusions", null, null).Properties["ExcludedKeys"].Value;

                if (result != null)
                {
                    foreach (var r in result)
                    {
                        Console.WriteLine(r.GetPropertyValue("RegistryKey"));
                    }
                }
            }
        }
    }
