无法在c#中删除注册表文件夹

本文关键字：删除 注册表 文件夹 | 更新日期: 2023-09-27 18:16:47

我试图使用c#代码删除注册表文件夹，但它抛出一个异常，即键不存在…!!但是如果key不存在，那么注册表对象不应该是空的但在这个例子中，它没有显示为空，它包含了一些值这是我的代码

bool IsDeleted = false;
            try
            {
                regkey = regkey.Replace(@"HKEY_LOCAL_MACHINE'", "");
                using (RegistryKey key = Registry.LocalMachine.OpenSubKey(regkey, true))
                {
                    if (key != null)//here it show that key is exists
                    {
                        IsDeleted = DeleteKey(key, regkey);//in this line It generate exception
                    }
                }
            }
            catch
            {
            }
             return IsDeleted;

这是删除代码

 public static bool DeleteKey(RegistryKey hKey, string strPath)
        {
            bool flag1 = false;
            int num1 = 0;
            int num2 = 0;
            try
            {
                num2 = 1;
                hKey.DeleteSubKeyTree(strPath);
                flag1 = true;
            }
            catch (Exception obj1) //when (?)
            {
                Exception exception2 = (Exception)obj1;
                Exception exception1 = exception2;
                if (num1 == 0)
                {
                    num1 = -1;
                    switch (num2)
                    {
                        case 1:
                            {
                                goto Label_0058;
                            }
                    }
                    throw;
                }
            }
        Label_0058:
            if (num1 != 0)
            {
            }
            return flag1;
        }

请帮我一下非常感谢

无法在c#中删除注册表文件夹

这是由于Windows 7的权限问题造成的

try
            {
                new System.Security.Permissions.RegistryPermission(System.Security.Permissions.PermissionState.Unrestricted).Assert();
                hKey.DeleteSubKeyTree(strPath);
                flag1 = true;
            }
            catch (Exception obj1) //when (?)
            {
            }
            finally
            {
                System.Security.Permissions.RegistryPermission.RevertAssert();
            }

您可以将此清单嵌入到您的应用程序中。
