TypeDescriptor.GetAssociation Method

Returns an instance of the type associated with the specified primary object.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

public static Object GetAssociation(
	Type type,
	Object primary
)

Parameters

type
Type: System.Type

The Type of the target component.

primary
Type: System.Object

The primary object of the association.

Return Value

Type: System.Object
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.

ExceptionCondition
ArgumentNullException

One or both of the parameters are null.

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.
