GetExports(Type, Type, String)

Source:

ExportProvider.GetExportOverrides.cs

Gets all the exports with the specified contract name.

public:
 System::Collections::Generic::IEnumerable<Lazy<System::Object ^, System::Object ^> ^> ^ GetExports(Type ^ type, Type ^ metadataViewType, System::String ^ contractName);

public System.Collections.Generic.IEnumerable<Lazy<object,object>> GetExports (Type type, Type? metadataViewType, string? contractName);

member this.GetExports : Type * Type * string -> seq<Lazy<obj, obj>>

Public Function GetExports (type As Type, metadataViewType As Type, contractName As String) As IEnumerable(Of Lazy(Of Object, Object))

Parameters

type

Type

The type parameter of the Lazy<T,TMetadata> objects to return.

metadataViewType

Type

The type of the metadata view of the Lazy<T,TMetadata> objects to return.

contractName

String

The contract name of the Lazy<T,TMetadata> object to return, or null or an empty string ("") to use the default contract name.

Returns

IEnumerable<Lazy<Object,Object>>

A collection of all the Lazy<T,TMetadata> objects for the contract matching contractName.

Exceptions

ObjectDisposedException

The CompositionContainer object has been disposed of.

ArgumentNullException

type is null.

InvalidOperationException

metadataViewType is not a valid metadata view type.

Remarks

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

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

GetExports<T,TMetadataView>()

Source:

ExportProvider.GetExportOverrides.cs
