public sealed class TypeDescriptionProviderAttribute : Attribute

The TypeDescriptionProviderAttribute type exposes the following members.

  NameDescription
Public methodTypeDescriptionProviderAttribute(String)Initializes a new instance of the TypeDescriptionProviderAttribute class using the specified type name.
Public methodTypeDescriptionProviderAttribute(Type)Initializes a new instance of the TypeDescriptionProviderAttribute class using the specified type.

  NameDescription
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)
Public propertyTypeNameGets the type name for the type description provider.

  NameDescription
Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

  NameDescription
Explicit interface implemetationPrivate method_Attribute.GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute.InvokeProvides 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.

NoteNote

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.
