[SerializableAttribute] [ComVisibleAttribute(true)] [AttributeUsageAttribute(AttributeTargets::Assembly|AttributeTargets::Class|AttributeTargets::Struct|AttributeTargets::Constructor|AttributeTargets::Method, AllowMultiple = true, Inherited = false)] public ref class CodeAccessSecurityAttribute abstract : public SecurityAttribute
The CodeAccessSecurityAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | CodeAccessSecurityAttribute | Initializes a new instance of CodeAccessSecurityAttribute with the specified SecurityAction. |
| Name | Description | |
|---|---|---|
![]() | Action | Gets or sets a security action. (Inherited from SecurityAttribute.) |
![]() | TypeId | When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.) |
![]() | Unrestricted | Gets or sets a value indicating whether full (unrestricted) permission to the resource protected by the attribute is declared. (Inherited from SecurityAttribute.) |
| Name | Description | |
|---|---|---|
![]() | CreatePermission | When overridden in a derived class, creates a permission object that can then be serialized into binary form and persistently stored along with the SecurityAction in an assembly's metadata. (Inherited from SecurityAttribute.) |
![]() | Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) |
![]() | Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | _Attribute::GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
![]() ![]() | _Attribute::GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
![]() ![]() | _Attribute::Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
This attribute class associates a SecurityAction, for example, Demand, with a custom security attribute.
The types that derive from CodeAccessSecurityAttribute are used to help restrict access to resources or securable operations.
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. Use the corresponding permission class derived from CodeAccessPermission for imperative security.
Notes to InheritorsAll permission attributes derived from this class must have only a single constructor that takes a SecurityAction as its only parameter.
The following example shows a permission attribute derived from the CodeAccessSecurityAttribute class.
using namespace System; using namespace System::IO; using namespace System::Runtime::Remoting; using namespace System::Security; using namespace System::Security::Permissions; using namespace System::Reflection; using namespace MyPermission; // Use the command line option '/keyfile' or appropriate project settings to sign this assembly. [assembly:System::Security::AllowPartiallyTrustedCallersAttribute]; [AttributeUsage(AttributeTargets::Method|AttributeTargets::Constructor|AttributeTargets::Class|AttributeTargets::Struct|AttributeTargets::Assembly,AllowMultiple=true,Inherited=false)] [Serializable] public ref class NameIdPermissionAttribute: public CodeAccessSecurityAttribute { private: String^ m_Name; bool m_unrestricted; public: NameIdPermissionAttribute( SecurityAction action ) : CodeAccessSecurityAttribute( action ) { m_Name = nullptr; m_unrestricted = false; } property String^ Name { String^ get() { return m_Name; } void set( String^ value ) { m_Name = value; } } virtual IPermission^ CreatePermission() override { if ( m_unrestricted ) { throw gcnew ArgumentException( "Unrestricted permissions not allowed in identity permissions." ); } else { if ( m_Name == nullptr ) return gcnew NameIdPermission( PermissionState::None ); return gcnew NameIdPermission( m_Name ); } } };
