GacIdentityPermission Class

Defines the identity permission for files originating in the global assembly cache. This class cannot be inherited.

System.Object
  System.Security.CodeAccessPermission
    System.Security.Permissions.GacIdentityPermission

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

[SerializableAttribute]
[ComVisibleAttribute(true)]
public sealed class GacIdentityPermission : CodeAccessPermission

The GacIdentityPermission type exposes the following members.

  NameDescription
Public methodGacIdentityPermission()Initializes a new instance of the GacIdentityPermission class.
Public methodGacIdentityPermission(PermissionState)Initializes a new instance of the GacIdentityPermission class with fully restricted PermissionState.

  NameDescription
Public methodAssertDeclares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. Using Assert can create security issues. (Inherited from CodeAccessPermission.)
Public methodCopyCreates and returns an identical copy of the current permission. (Overrides CodeAccessPermission.Copy().)
Public methodDemandForces a SecurityException at run time if all callers higher in the call stack have not been granted the permission specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodDeny Obsolete. Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodEqualsDetermines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission. (Inherited from CodeAccessPermission.)
Public methodFromXmlCreates a permission from an XML encoding. (Overrides CodeAccessPermission.FromXml(SecurityElement).)
Public methodGetHashCodeGets a hash code for the CodeAccessPermission object that is suitable for use in hashing algorithms and data structures such as a hash table. (Inherited from CodeAccessPermission.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIntersectCreates and returns a permission that is the intersection of the current permission and the specified permission. (Overrides CodeAccessPermission.Intersect(IPermission).)
Public methodIsSubsetOfIndicates whether the current permission is a subset of the specified permission. (Overrides CodeAccessPermission.IsSubsetOf(IPermission).)
Public methodPermitOnlyPrevents callers higher in the call stack from using the code that calls this method to access all resources except for the resource specified by the current instance. (Inherited from CodeAccessPermission.)
Public methodToStringCreates and returns a string representation of the current permission object. (Inherited from CodeAccessPermission.)
Public methodToXmlCreates an XML encoding of the permission and its current state. (Overrides CodeAccessPermission.ToXml().)
Public methodUnionCreates and returns a permission that is the union of the current permission and the specified permission. (Overrides CodeAccessPermission.Union(IPermission).)

Files are either in the global assembly cache, or they are not. There are no variations to the permission granted, so all GacIdentityPermission objects are equal.

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. Starting with the .NET Framework version 2.0, 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.
