【问题描述】：

我尝试通过 C# 脚本删除测试密钥。以下代码是我的脚本，我还在此项目 UAC 的清单文件中添加了管理值。但它仍然不起作用。甚至以管理员模式重新启动 Visual Studio 2017。错误消息说无法写入注册表项。不知道脚本有什么问题。

using System.Collections.Generic;

using Microsoft.Win32;
using System.Security;
using System.Security.AccessControl;
using System.Security.Principal;


namespace temp_code_tester
{
class Program
{
    static void Main(string[] args)
    {
        //Get current login account info from another Class
        //string userName = WindowsIdentity.GetCurrent().Name;
        //var SecCheck = new SecutriyProcesser();
        //SecCheck.AddRule(userName);


        var RunCheck = new AccessRegistry();
        RunCheck.ACL("Test");

    }
}

class AccessRegistry
{
    public void ACL(string name)
    {
        Console.WriteLine("Getting the registry keys.....");
        Console.WriteLine("---------------------------------------------\n");

        //Open the SOFTWARE keys and input those keys into array
        RegistryKey SoftKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE");
        string[] lists = SoftKey.GetSubKeyNames();

        foreach (string KeyName in lists)
        {
            Console.WriteLine(KeyName);
        }

        foreach (string value in lists)
        {
            if (value.Contains(name)) // if we find the key, then lists all subkeys
            {
                //Registry.LocalMachine.DeleteSubKeyTree(value);
                Console.WriteLine("\nMatch one: {0}", value);

                var RightKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\" + value);
                string[] SubList = RightKey.GetSubKeyNames();

                foreach (string SubValue in SubList)
                {
                    Console.WriteLine("Folder: {0} is under this key", SubValue);
                }

                if (SubList.Length > 1)
                {

【解决方案1】：

您忘记了“OpenSubkey”方法的“可写”参数。试试这个：

RegistryKey SoftKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE", true);

它应该像这样工作。

编辑：如果您在调试时不以管理员身份运行 Visual Studio，此方法可能会失败。
