Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Remarks

RegistryPermission describes protected operations on registry variables. Registry variables should not be stored in memory locations where code without RegistryPermission can access them. If the registry object is passed to an untrusted caller it can be misused.

The allowed registry access types are defined by RegistryPermissionAccess. If more than one type of access is desired, they can be combined using the bitwise OR operation as shown in the code sample that follows.

Registry permission is defined in terms of canonical absolute paths; checks should always be made with canonical pathnames. Key access implies access to all values it contains and all variables under it.

Caution[note] RegistryPermission grants permission for all paths to a key, including both HKEY_CURRENT_USER and HKEY_USERS. To Deny access to a key, you must Deny all possible paths to the key. For example, to Deny access to HKEY_CURRENT_USER\Software\Microsoft\Cryptography, you must Deny HKEY_CURRENT_USER\Software\Microsoft\Cryptography, HKEY_USERS\.......\Software\Microsoft\Cryptography and any other path that you can use to access the key. A better technique to deal with multiple paths is to use a combination of PermitOnly and Deny. For more information on this subject and the use of PermitOnly with Deny, see Canonicalization Problems Using Deny in the Deny topic.

Example

[Visual Basic, C#, C++] After the following code the RegistryPermission f represents permission to read the values from the CentralProcessor key. Read and Write are values of RegistryPermissionAccess.

[Visual Basic] 
Dim f As New RegistryPermission( _
RegistryPermissionAccess.Read, _
"HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0")

[C#] 
RegistryPermission f = new RegistryPermission(
RegistryPermissionAccess.Read, 
"HKEY_LOCAL_MACHINE\\HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0");

[C++] 
RegistryPermission* f = new RegistryPermission(
RegistryPermissionAccess::Read, 
S"HKEY_LOCAL_MACHINE\\HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0");

[Visual Basic, C#, C++] The following code adds permission to read from and write to the FloatingPointProcessor key to the RegistryPermission f.

[Visual Basic] 
f.AddPathList( _
RegistryPermissionAccess.Write Or RegistryPermissionAccess.Read, _
"HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\FloatingPointProcessor\0")

[C#] 
f.AddPathList(
RegistryPermissionAccess.Write | RegistryPermissionAccess.Read,
"HKEY_LOCAL_MACHINE\\HARDWARE\\DESCRIPTION\\System\\FloatingPointProcessor\\0");

[C++] 
f->AddPathList(static_cast<RegistryPermissionAccess>(RegistryPermissionAccess::Write | RegistryPermissionAccess::Read),
S"HKEY_LOCAL_MACHINE\\HARDWARE\\DESCRIPTION\\System\\FloatingPointProcessor\\0");

[Visual Basic, C#, C++] The RegistryPermission f now represents the permission to read from the CentralProcessor key and to read from and write to the FloatingPointProcessor key.

[Visual Basic, C#, C++] The following example demonstrates many RegistryPermission members.
