public sealed class StrongNameIdentityPermissionAttribute : CodeAccessSecurityAttribute

The StrongNameIdentityPermissionAttribute type exposes the following members.

  NameDescription
Public methodStrongNameIdentityPermissionAttributeInitializes a new instance of the StrongNameIdentityPermissionAttribute class with the specified SecurityAction.
Top

  NameDescription
Public propertyActionGets or sets a security action. (Inherited from SecurityAttribute.)
Public propertyNameGets or sets the name of the strong name identity.
Public propertyPublicKeyGets or sets the public key value of the strong name identity expressed as a hexadecimal string.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Public propertyUnrestrictedGets or sets a value indicating whether full (unrestricted) permission to the resource protected by the attribute is declared. (Inherited from SecurityAttribute.)
Public propertyVersionGets or sets the version of the strong name identity.
Top

  NameDescription
Public methodCreatePermissionCreates and returns a new StrongNameIdentityPermission. (Overrides SecurityAttribute.CreatePermission().)
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Important noteImportant

Starting with the .NET Framework 4, identity permissions are not used.

In the .NET Framework versions 1.0 and 1.1, demands on the identity permissions are effective, even when the calling assembly is fully trusted. That is, although the calling assembly has full trust, a demand for an identity permission fails if the assembly does not meet the demanded criteria. In the .NET Framework version 2.0 and later, demands for identity permissions are ineffective if the calling assembly has full trust. This assures consistency for all permissions, eliminating the treatment of identity permissions as a special case.

The scope of the declaration that is allowed depends on the SecurityAction that is used. You can obtain the key string for this attribute by running the Strong Name tool (Sn.exe) with the token and public key options (Sn -tp keyfile) against a file that has an Authenticode signature. For more information, see Sn.exe (Strong Name Tool).

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 StrongNameIdentityPermissionAttribute attribute can be used to define strong-name requirements for access to public members at the assembly level. In the .NET Framework version 2.0 and later, you can also use the InternalsVisibleToAttribute attribute to specify that all nonpublic types in that assembly are visible to another assembly. For more information, see Friend Assemblies (C# and Visual Basic) or Friend Assemblies (Visual Basic).
