RegistryPermissionAttribute Class

Allows security actions for RegistryPermission to be applied to code using declarative security. This class cannot be inherited.

Namespace: System.Security.Permissions
Assembly: mscorlib (in mscorlib.dll)

[SerializableAttribute] 
[AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false)] 
[ComVisibleAttribute(true)] 
public sealed class RegistryPermissionAttribute : CodeAccessSecurityAttribute
/** @attribute SerializableAttribute() */ 
/** @attribute AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false) */ 
/** @attribute ComVisibleAttribute(true) */ 
public final class RegistryPermissionAttribute extends CodeAccessSecurityAttribute
SerializableAttribute 
AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple=true, Inherited=false) 
ComVisibleAttribute(true) 
public final class RegistryPermissionAttribute extends CodeAccessSecurityAttribute
Not applicable.

The scope of the declaration that is allowed depends on the SecurityAction that is used.

The security information declared by a security attribute is stored in the metadata of the attribute target and is accessed by the system at run time. Security attributes are used only for declarative security. For imperative security, use the corresponding permission class.

The following example of a declarative attribute shows the correct way to request RegistryPermission for access to the given registry value and states that you must have at least this permission to run your code.

[assembly:RegistryPermissionAttribute(SecurityAction.RequestMinimum,
Read="HKEY_LOCAL_MACHINE\\HARDWARE\\DESCRIPTION\\System\\CentralProcessor")]
//In C#, you must specify that you are using the assembly scope when making a request.

/** @assembly RegistryPermissionAttribute(SecurityAction.RequestMinimum, 
    Read = "HKEY_LOCAL_MACHINE\\HARDWARE\\DESCRIPTION\\System\\CentralProcessor")
 */
// In VJ#, you must specify that you are using the assembly scope when 
// making a request.

The following example shows how to demand that the calling code has unrestricted RegistryPermission at link time. Demands are typically made in managed libraries (DLLs) to help protect methods or classes from potentially harmful code.

[RegistryPermissionAttribute(SecurityAction.Demand, Unrestricted=true)]

/** @attribute RegistryPermissionAttribute(SecurityAction.Demand,
    Unrestricted = true)
 */
