TypeDescriptionProviderAttribute Class


Specifies the custom type description provider for a class. This class cannot be inherited.

Namespace:   System.ComponentModel
Assembly:  System (in System.dll)


[AttributeUsageAttribute(AttributeTargets.Class, Inherited = true)]
public sealed class TypeDescriptionProviderAttribute : Attribute


Initializes a new instance of the TypeDescriptionProviderAttribute class using the specified type name.


Initializes a new instance of the TypeDescriptionProviderAttribute class using the specified type.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


Gets the type name for the type description provider.


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

This attribute supplies a way for developers to provide custom metadata for their authored classes. This capability extends the static type information functionality in the TypeDescriptor class, which by default only obtains type information directly from metadata of the compiled classes.


For a more dynamic way to provide custom metadata for your authored classes, see the AddProvider method.

Tagging a class with a TypeDescriptionProviderAttribute will associate a TypeDescriptionProvider with that class. A TypeDescriptionProvider provides supplemental metadata information about the tagged class. For example, the GetTypeDescriptor method returns an ICustomTypeDescriptor that defines additional type information, such as attributes, events, and properties. Subsequently, if a TypeDescriptionProvider member is used to investigate the tagged class, it will discover both the default and custom type information.

This attribute can only be applied to classes and is inherited by derived classes.

This attribute cannot be derived from.
