GacIdentityPermission Class

Definition

Caution

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

Defines the identity permission for files originating in the global assembly cache. 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.

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

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

In .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 .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.

Constructors

GacIdentityPermission()

Initializes a new instance of the GacIdentityPermission class.

GacIdentityPermission(PermissionState)

Initializes a new instance of the GacIdentityPermission class with fully restricted PermissionState.

Methods

Assert()

Declares 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)
Copy()

Creates and returns an identical copy of the current permission.

Demand()

Forces 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)
Deny()
Obsolete.
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)
Equals(Object)

Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.

(Inherited from CodeAccessPermission)
FromXml(SecurityElement)

Creates a permission from an XML encoding.

GetHashCode()

Gets 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)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
Intersect(IPermission)

Creates and returns a permission that is the intersection of the current permission and the specified permission.

IsSubsetOf(IPermission)

Indicates whether the current permission is a subset of the specified permission.

MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
PermitOnly()

Prevents 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)
ToString()

Creates and returns a string representation of the current permission object.

(Inherited from CodeAccessPermission)
ToXml()

Creates an XML encoding of the permission and its current state.

Union(IPermission)

Creates and returns a permission that is the union of the current permission and the specified permission.
