RegistrySecurity访问被拒绝.C#

本文关键字：拒绝 访问 RegistrySecurity | 更新日期: 2023-09-27 18:00:16

我目前在编写应用程序以设置某些Legacy密钥的权限时遇到问题。遗留密钥被完全锁定，要在regedit中实际修改它们，您必须拥有所有权，然后添加自己的完全控制权。当试图在代码中复制这一点时，我无法获得写入密钥，并出现错误"访问被拒绝"。示例代码：

RegistrySecurity rs = new RegistrySecurity();
rs.AddAccessRule(new RegistryAccessRule("Administrators", RegistryRights.FullControl, AccessControlType.Allow));
rs.SetOwner(new NTAccount("Administrators"));
return LocalMachine.CreateSubKey(post, RegistryKeyPermissionCheck.ReadWriteSubTree, rs);

任何想法都将不胜感激。我也尝试过要求写访问的OpenSubKey，但就是无法获得密钥。

谢谢大家。

我终于找到了解决方案。你必须用"ChangePermissions"打开密钥，然后为自己更改权限。。。然后在完全控制的情况下重新打开钥匙以更换所有者。方法如下。

RegistryKey rk = LocalMachine.OpenSubKey(subkey, RegistryKeyPremissionsCheck.ReadWriteSubTree, RegistryRights.ChangePermissions | RegistryRights.ReadKey);//Get the registry key desired with ChangePermissions Rights.
RegistrySecurity rs = new RegistrySecurity();
rs.AddAccessRule(new RegistryAccessRule("Administrator", RegistryRights.FullControl, InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit, PropagationFlags.InheritOnly, AccessControlType.Allow));//Create access rule giving full control to the Administrator user.
rk.SetAccessControl(rs); //Apply the new access rule to this Registry Key.
rk = LocalMachine.OpenSubKey(subkey, RegistryKeyPremissionsCheck.ReadWriteSubTree, RegistryRights.FullControl); // Opens the key again with full control.
rs.SetOwner(new NTAccount("Administrator"));// Set the securitys owner to be Administrator
rk.SetAccessControl(rs);// Set the key with the changed permission so Administrator is now owner.

这对我有效。如果对你有效，请告诉我：）

如果您不是以管理员身份登录，或者您需要其他用户的权限，请将管理员更改为其他用户。

使用该代码运行应用程序时，是否右键单击exe并选择"以管理员身份运行"？

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

首先必须设置具有权限FULL-ACCESS的子密钥权限

RegistryKey rkey = LocalMachine.OpenSubKey(_subKey, RegistryKeyPermissionCheck.ReadWriteSubTree, gistryRights.ChangePermissions);
if (rkey == null)
 throw new Exception("Not Open");
//-------
RegistrySecurity _registrySecurity =new RegistrySecurity();//Or rkey.GetAccessControl();
WindowsIdentity _windowsIdentity = System.Security.Principal.WindowsIdentity.GetCurrent();
RegistryAccessRule _accessRule = new RegistryAccessRule(_windowsIdentity.Name, RegistryRights.FullControl, InheritanceFlags.ObjectInherit | InheritanceFlags.ContainerInherit, PropagationFlags.None, AccessControlType.Allow);
_registrySecurity.AddAccessRule(_accessRule);
_registrySecurity.SetAccessRuleProtection(false, true);
 rkey.SetAccessControl(_registrySecurity);
//--------Now, Set owner
_registrySecurity.SetGroup(new NTAccount("Administrators"));  //This is optional
var SID = new System.Security.Principal.NTAccount("XXX''Users");
_registrySecurity.SetOwner(SID);
rkey.SetAccessControl(_registrySecurity);

XXX：您的帐户名

        RegistryKey rkey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE'Norton'SecurityStatusSDK", RegistryKeyPermissionCheck.ReadWriteSubTree, RegistryRights.ChangePermissions);
        if (rkey == null)
            throw new Exception("Not Open");
        //-------
        RegistrySecurity _registrySecurity = new RegistrySecurity();//Or rkey.GetAccessControl();
        WindowsIdentity _windowsIdentity = System.Security.Principal.WindowsIdentity.GetCurrent();
        RegistryAccessRule _accessRule = new RegistryAccessRule(_windowsIdentity.Name, RegistryRights.FullControl, InheritanceFlags.ObjectInherit | InheritanceFlags.ContainerInherit, PropagationFlags.None, AccessControlType.Allow);
        _registrySecurity.AddAccessRule(_accessRule);
        _registrySecurity.SetAccessRuleProtection(false, true);
        try
        {
            rkey.SetAccessControl(_registrySecurity);// <---"Attempted to perform an unauthorized operation."
        }
        catch (UnauthorizedAccessException e)
        {
        }
        //--------Now, Set owner
        _registrySecurity.SetGroup(new NTAccount("Administrators"));  //This is optional
        var SID = new System.Security.Principal.NTAccount("XXX''Users");
        _registrySecurity.SetOwner(SID);
        rkey.SetAccessControl(_registrySecurity);

我安装了Norton Internet Security

Microsoft Visual Studio 2015（管理员）

_subKey = SOFTWARE'Wow6432Node'Norton

rkey.SetAccessControl(_registrySecurity);->"试图执行未经授权的操作。"`
