Parameters

contractName

The contract name of the Export<T, TMetadataView> objects to return, or null or an empty string ("") to use the default contract name.

Return Value

The Export<T, TMetadataView> objects with the specified contract name if found; otherwise, an empty ExportCollection<T, TMetadataView> object.

ExceptionCondition
