The TypeDescriptorPermission type exposes the following members.

  Name Description
Public property Flags Gets or sets the TypeDescriptorPermissionFlags for the type descriptor.

  Name Description
Public method 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.)
Public method Copy When implemented by a derived class, creates and returns an identical copy of the current permission object. (Overrides CodeAccessPermission.Copy().)
Public method 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.)
Public method Deny 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 method Equals Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission. (Inherited from CodeAccessPermission.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method FromXml When overridden in a derived class, reconstructs a security object with a specified state from an XML encoding. (Overrides CodeAccessPermission.FromXml(SecurityElement).)
Public method 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.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method Intersect When implemented by a derived class, creates and returns a permission that is the intersection of the current permission and the specified permission. (Overrides CodeAccessPermission.Intersect(IPermission).)
Public method IsSubsetOf When implemented by a derived class, determines whether the current permission is a subset of the specified permission. (Overrides CodeAccessPermission.IsSubsetOf(IPermission).)
Public method IsUnrestricted Gets a value that indicates whether the type descriptor may be called from partially trusted code.
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method 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.)
Public method ToString Creates and returns a string representation of the current permission object. (Inherited from CodeAccessPermission.)
Public method ToXml When overridden in a derived class, creates an XML encoding of the security object and its current state. (Overrides CodeAccessPermission.ToXml().)
Public method Union When overridden in a derived class, creates a permission that is the union of the current permission and the specified permission. (Overrides CodeAccessPermission.Union(IPermission).)
