Represents the identity of a software publisher. This class cannot be inherited.

System.Object
  System.Security.CodeAccessPermission
    System.Security.Permissions.PublisherIdentityPermission

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

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

The PublisherIdentityPermission type exposes the following members.

  NameDescription
Public methodPublisherIdentityPermission(PermissionState)Initializes a new instance of the PublisherIdentityPermission class with the specified PermissionState.
Public methodPublisherIdentityPermission(X509Certificate)Initializes a new instance of the PublisherIdentityPermission class with the specified Authenticode X.509v3 certificate.

  NameDescription
Public propertyCertificateGets or sets an Authenticode X.509v3 certificate that represents the identity of the software publisher.

  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.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodFromXmlReconstructs a permission with a specified state 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 methodIsSubsetOfDetermines whether the current permission is a subset of the specified permission. (Overrides CodeAccessPermission.IsSubsetOf(IPermission).)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
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 methodUnionInfrastructure. Creates a permission that is the union of the current permission and the specified permission. (Overrides CodeAccessPermission.Union(IPermission).)

Important noteImportant

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

   In the .NET Framework versions 1.0 and 1.1, identity permissions cannot have an Unrestricted permission state value. Starting with the .NET Framework version 2.0, identity permissions can have any permission state value. This means that in 2.0 and later versions, identity permissions have the same behavior as permissions that implement the IUnrestrictedPermission interface. That is, a demand for an identity always succeeds, regardless of the identity of the assembly, if the assembly has been granted full trust.

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.

NoteNote

By default, code access security does not check for Publisher evidence. Unless your computer has a custom code group based on the PublisherMembershipCondition class, you can improve performance by bypassing Authenticode signature verification. This is accomplished by configuring the runtime to not provide Publisher evidence for code access security. For more information about how to configure this option and which applications can use it, see the <generatePublisherEvidence> element.
