Returns an instance of the type associated with the specified primary object.
public:
static System::Object ^ GetAssociation(Type ^ type, System::Object ^ primary);
public static object GetAssociation (Type type, object primary);
static member GetAssociation : Type * obj -> obj
Public Shared Function GetAssociation (type As Type, primary As Object) As Object
Parameters
- primary
- Object
The primary object of the association.
Returns
An instance of the secondary type that has been associated with the primary object if an association exists; otherwise, primary
if no specified association exists.
Exceptions
One or both of the parameters are null
.
Remarks
If a previous association has been made for the type
parameter using the CreateAssociation method, then the GetAssociation method returns the correct secondary object to invoke for the requested type. Otherwise, GetAssociation searches for a compatible designer for type
and returns the designer if one is found. This method never returns null
.
A WeakReference is used to maintain the association between the primary and secondary object; therefore, this method does not prevent either the primary or secondary object from being finalized and reclaimed by garbage collection.
