StrongNameIdentityPermissionAttribute Class

Definition

Namespace:

System.Security.Permissions

Assembly:

System.Security.Permissions.dll

Caution

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

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

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.

Important

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

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.

Constructors

StrongNameIdentityPermissionAttribute(SecurityAction)

Initializes a new instance of the StrongNameIdentityPermissionAttribute class with the specified SecurityAction.

Properties

Action	Gets or sets a security action. (Inherited from SecurityAttribute)
Name	Gets or sets the name of the strong name identity.
PublicKey	Gets or sets the public key value of the strong name identity expressed as a hexadecimal string.
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)
Version	Gets or sets the version of the strong name identity.

Methods

CreatePermission()	Creates and returns a new StrongNameIdentityPermission.
Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
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(Object)	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)
