操作注册表 Timothy

 附上一个管理注册表的示例。

 1. 主程序。

 1static void Main(string[] args)
 2{
 3    Program p = new Program();
 4    p.getRegistry(RegistryHive.LocalMachine, @"SOFTWARE\Test");//读取注册表子键，带有类型判断
 5
 6    Console.WriteLine(p.getRegistry(RegistryHive.LocalMachine, @"SOFTWARE\Test", "Str"));//读取具体的键值
 7    Console.WriteLine(p.getRegistry(RegistryHive.CurrentUser, @"Console", "FaceName"));
 8
 9    RegSecurity();//带安全验证的注册表操作

    Console.ReadLine();

}

 2. 权限操作和创建注册表。

 1private static void RegSecurity()
 2{
 3    const string TestKey = "TestKey3927";
 4    RegistryKey cu = Registry.CurrentUser;
 5
 6    string user = Environment.UserDomainName + "\\" + Environment.UserName;
 7
 8    System.Security.AccessControl.RegistrySecurity mSec = new System.Security.AccessControl.RegistrySecurity();
 9    System.Security.AccessControl.RegistryAccessRule rule = new System.Security.AccessControl.RegistryAccessRule(user, System.Security.AccessControl.RegistryRights.ReadKey | System.Security.AccessControl.RegistryRights.WriteKey | System.Security.AccessControl.RegistryRights.Delete, System.Security.AccessControl.InheritanceFlags.ContainerInherit, System.Security.AccessControl.PropagationFlags.None, System.Security.AccessControl.AccessControlType.Allow);
    mSec.AddAccessRule(rule);

    rule = new System.Security.AccessControl.RegistryAccessRule(user, System.Security.AccessControl.RegistryRights.ChangePermissions, System.Security.AccessControl.InheritanceFlags.ContainerInherit, System.Security.AccessControl.PropagationFlags.InheritOnly | System.Security.AccessControl.PropagationFlags.NoPropagateInherit, System.Security.AccessControl.AccessControlType.Allow);
    mSec.AddAccessRule(rule);

    ShowSecurity(mSec);

    RegistryKey rk = cu.CreateSubKey(TestKey, RegistryKeyPermissionCheck.ReadWriteSubTree, mSec);
    RegistryKey rkChild = rk.CreateSubKey("ChildKey", RegistryKeyPermissionCheck.ReadWriteSubTree);
    RegistryKey rkGrandChild = rkChild.CreateSubKey("GrandChildKey", RegistryKeyPermissionCheck.ReadWriteSubTree);
    rkGrandChild.SetValue("ValueIs", "This is the value!", RegistryValueKind.String);

    Show(rk);
    Show(rkChild);
    Show(rkGrandChild);

    rkGrandChild.Close();
    rkChild.Close();
    rk.Close();
    cu.DeleteSubKeyTree(TestKey);
}

 3. 显示注册表键值

private static void Show(RegistryKey rk)
{
    Console.WriteLine(rk.Name);
    ShowSecurity(rk.GetAccessControl());
}

 4. 显示安全信息

 1private static void ShowSecurity(System.Security.AccessControl.RegistrySecurity security)
 2{
 3    Console.WriteLine("\r\nCurrent   access   rules:\r\n");
 4    foreach (System.Security.AccessControl.RegistryAccessRule ar in security.GetAccessRules(true, true, typeof(System.Security.Principal.NTAccount)))
 5    {
 6        Console.WriteLine("User:{0}", ar.IdentityReference);
 7        Console.WriteLine("Type:{0}", ar.AccessControlType);
 8        Console.WriteLine("Rights:{0}", ar.RegistryRights);
 9        Console.WriteLine("Inheritance:{0}", ar.InheritanceFlags);
        Console.WriteLine("Propagation:{0}", ar.PropagationFlags);
        Console.WriteLine("Inherited?{0}", ar.IsInherited);
        Console.WriteLine();
    }
}

 5. 读取注册表

 1private string getRegistry(RegistryHive hive, string subKey, string value)
 2{
 3    RegistryKey regKey = null;
 4    switch (hive)
 5    {
 6        case RegistryHive.LocalMachine:
 7            regKey = Registry.LocalMachine;
 8            break;
 9        case RegistryHive.CurrentUser:
            regKey = Registry.CurrentUser;
            break;
        default:
            regKey = null;
            break;
    }

    RegistryKey key = regKey.OpenSubKey(subKey);

    string str = Registry.GetValue(key.ToString(), value, "Get the value from the registry failed!").ToString();

    return str;
}

 6. 带类型判断的读取注册表。

 1
 2private void getRegistry(RegistryHive hive,string subKey)
 3{
 4    RegistryKey regKey = null;
 5    switch (hive)
 6    {
 7        case RegistryHive.LocalMachine:
 8            regKey = Registry.LocalMachine;
 9            break;
        case RegistryHive.CurrentUser:
            regKey = Registry.CurrentUser;
            break;
        default:
            regKey = null;
            break;
    }

    RegistryKey key = regKey.OpenSubKey(subKey);

    string[] strr = key.GetValueNames();
    foreach (string s in strr)
    {
        RegistryValueKind rvk = key.GetValueKind(s);
        switch (rvk)
        {
            case RegistryValueKind.String:
                string values = (string)key.GetValue(s);
                Console.Write("\r\n {0} ({1}) = \"{2}\"", s, rvk, values);
                //for (int i = 1; i < values.Length; i++)
                //{
                //    Console.Write(", \"{0}\"", values[i]);
                //}
                Console.WriteLine();
                break;
            case RegistryValueKind.Binary:
                byte bytes = (byte)key.GetValue(s);
                Console.Write("\r\n {0} ({1}) = {2:X2}", s, rvk, bytes);
                //for (int i = 1; i < bytes.Length; i++)
                //{
                //    // Display each byte as two hexadecimal digits.
                //    Console.Write(" {0:X2}", bytes[i]);
                //}
                Console.WriteLine();
                break;
            default:
                break;
        }
    }
}
