ExportAttribute Constructor (Type)

Initializes a new instance of the ExportAttribute class, exporting the type or member marked with this attribute under a contract name derived from the specified type.

Namespace:  System.ComponentModel.Composition
Assembly:  System.ComponentModel.Composition (in System.ComponentModel.Composition.dll)
public ExportAttribute(
	Type contractType
)

Parameters

contractType
Type: System.Type

A type from which to derive the contract name that is used to export the type or member marked with this attribute, or null to use the default contract name.

The contract name is the result of calling the GetContractName method on contractType.

The default contract name is the result of calling the GetContractName method on the property or field type, or on the type that is marked with this attribute.

Methods marked with this attribute must specify a contract name or a type by using either ExportAttribute(String) or ExportAttribute(Type).

The contract name is compared by using the Ordinal property to perform a case-sensitive, non-linguistic comparison.
