Provides supplemental metadata to the TypeDescriptor.

Thetype exposes the following members.
|CreateInstance||Creates an object that can substitute for another data type.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetCache||Gets a per-object cache, accessed as an IDictionary of key/value pairs.|
|GetExtendedTypeDescriptor||Gets an extended custom type descriptor for the given object.|
|GetExtenderProviders||Gets the extender providers for the specified object.|
|GetFullComponentName||Gets the name of the specified component, or null if the component has no name.|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetReflectionType(Object)||Performs normal reflection against the given object.|
|GetReflectionType(Type)||Performs normal reflection against a type.|
|GetReflectionType(Type, Object)||Performs normal reflection against the given object with the given type.|
|GetRuntimeType||Converts a reflection type into a runtime type.|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|GetTypeDescriptor(Object)||Gets a custom type descriptor for the given object.|
|GetTypeDescriptor(Type)||Gets a custom type descriptor for the given type.|
|GetTypeDescriptor(Type, Object)||Gets a custom type descriptor for the given type and object.|
|IsSupportedType||Gets a value that indicates whether the specified type is compatible with the type description and its chain of type description providers.|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The class dynamically extends the type information associated with a type or object by adding, modifying, or hiding characteristics such as attributes, properties, and events. There can be multiple type description provider classes that offer metadata to a single TypeDescriptor.
There are two ways to associate a with a TypeDescriptor:
At design time, when the target class can be assigned the appropriate TypeDescriptionProviderAttribute tag.
The class relies on a parent object of the same type, supplied during construction. This allows classes that derive from CustomTypeDescriptor to selectively override methods.
Instances of are only built upon demand, minimizing the impact of custom type information on performance.
This class cannot be inherited.
The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
Your derived type might be marked as internal or private, but an instance of your type can be created with the TypeDescriptor class. Do not write insecure code by assuming the caller is trusted. Assume instead that callers might create instances of your type in partial trust.
