ReflectionPermissionAttribute Class

Definition

Namespace:

System.Security.Permissions

Assembly:

System.Security.Permissions.dll

Source:

ReflectionPermissionAttribute.cs

Caution

Code Access Security is not supported or honored by the runtime.

Allows security actions for ReflectionPermission to be applied to code using declarative security.

Remarks

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

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.

Constructors

Name	Description
ReflectionPermissionAttribute(SecurityAction)	Initializes a new instance of the ReflectionPermissionAttribute class with the specified SecurityAction.

Properties

Name	Description
Flags	Gets or sets the current allowed uses of reflection.
MemberAccess	Gets or sets a value that indicates whether invocation of operations on non-public members is allowed.
ReflectionEmit	Obsolete. Gets or sets a value that indicates whether use of certain features in System.Reflection.Emit, such as emitting debug symbols, is allowed.
RestrictedMemberAccess	Gets or sets a value that indicates whether restricted invocation of non-public members is allowed. Restricted invocation means that the grant set of the assembly that contains the non-public member that is being invoked must be equal to, or a subset of, the grant set of the invoking assembly.
TypeInformation	Obsolete. Gets or sets a value that indicates whether reflection on members that are not visible is allowed.

Methods

Name	Description
CreatePermission()	Creates and returns a new ReflectionPermission.
