Syntax

Visual Basic
C#

'Declaration
 
Public Function WithTypeFilter( _
   ByVal type As Type, _
   ByVal exportFilter As Func(Of Export,Boolean) _
) As CompositionContext

'Usage
 
Dim instance As CompositionContext
Dim type As Type
Dim exportFilter As Func(Of Export,Boolean)
Dim value As CompositionContext
 
value = instance.WithTypeFilter(type, exportFilter)

public CompositionContext WithTypeFilter( 
   Type type,
   Func<Export,bool> exportFilter
)

Parameters

type
exportFilter: A filter for exported metadata

Remarks

If you've decorated your classes with the ExportMetadata attribute to provide metadata about the exported type you can filter for these types in your CompositionContext by providing an export filter. Use BuildExportFilter to create the filter.

You can use a type filter instead of a global filter if the metadata applies only to a specific type.
