InternalTypeHelper Class

Abstract class used internally by the WPF XAML compiler to support the use of internal types.

Namespace:  System.Windows.Markup
Assembly:  WindowsBase (in WindowsBase.dll)

public abstract class InternalTypeHelper

The InternalTypeHelper type exposes the following members.

Protected methodInternalTypeHelperInitializes a new instance of the InternalTypeHelper class.

Protected methodAddEventHandlerWhen overridden in a derived (generated) class, attaches an event handler delegate to an internal event.
Protected methodCreateDelegateWhen overridden in a derived (generated) class, creates an event delegate referencing a non-public handler method.
Protected methodCreateInstanceWhen overridden in a derived (generated) class, creates an instance of an internal type.
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
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 methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Protected methodGetPropertyValueWhen overridden in a derived (generated) class, gets the value of an internal property on the target object
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodSetPropertyValueWhen overridden in a derived (generated) class, sets the value on an internal property on the target object.
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The InternalTypeHelper class is not intended for use by anything other than the WPF XAML markup compiler.

When compiling a XAML file, you can use public types, but you can also use internal types subject to the same limitations that exist on code access to internal types. InternalTypeHelper enables support of internal access level types for markup. This involves the compiler creating a generated class that derives from InternalTypeHelper and implements its members. The generated class exists in a security and access context such that only the same assembly or other assemblies specifically attributed for shared internal access can reference the generated class and thus the internal types.
