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

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.

The TypeDescriptorPermission class defines access to the following methods on the TypeDescriptor class.

• AddProviderTransparent(TypeDescriptionProvider, Object)

• AddProviderTransparent(TypeDescriptionProvider, Type)

• RemoveProviderTransparent(TypeDescriptionProvider, Object)

• RemoveProviderTransparent(TypeDescriptionProvider, Type)

Constructors

TypeDescriptorPermission(PermissionState)	Initializes a new instance of the TypeDescriptorPermission class.
TypeDescriptorPermission(TypeDescriptorPermissionFlags)	Initializes a new instance of the TypeDescriptorPermission class with the specified permission flags.

Properties

Flags

Gets or sets the TypeDescriptorPermissionFlags for the type descriptor.

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()	When implemented by a derived class, creates and returns an identical copy of the current permission object.
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. 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)	When overridden in a derived class, reconstructs a security object with a specified state 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)	When implemented by a derived class, creates and returns a permission that is the intersection of the current permission and the specified permission.
IsSubsetOf(IPermission)	When implemented by a derived class, determines whether the current permission is a subset of the specified permission.
IsUnrestricted()	Gets a value that indicates whether the type descriptor may be called from partially trusted code.
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()	When overridden in a derived class, creates an XML encoding of the security object and its current state.
Union(IPermission)	When overridden in a derived class, creates a permission that is the union of the current permission and the specified permission.
