Definition

Gets a metadata constraint that has the specified type and name, if it exists.

public:
generic <typename T>
 bool TryUnwrapMetadataConstraint(System::String ^ constraintName, [Runtime::InteropServices::Out] T % constraintValue, [Runtime::InteropServices::Out] System::Composition::Hosting::Core::CompositionContract ^ % remainingContract);
public bool TryUnwrapMetadataConstraint<T> (string constraintName, out T constraintValue, out System.Composition.Hosting.Core.CompositionContract remainingContract);
member this.TryUnwrapMetadataConstraint : string * 'T * CompositionContract -> bool
Public Function TryUnwrapMetadataConstraint(Of T) (constraintName As String, ByRef constraintValue As T, ByRef remainingContract As CompositionContract) As Boolean

Type Parameters

T

The type of the metadata constraint value.

Parameters

constraintName
String
