Returns the relevant Add method for a XamlTypeInvoker that is relevant to a collection or dictionary.

Namespace:   System.Xaml.Schema
Assembly:  System.Xaml (in System.Xaml.dll)

public virtual MethodInfo GetAddMethod(
	XamlType contentType


Type: System.Xaml.XamlType

XamlType for the item type that is used by the Add method.

Return Value

Type: System.Reflection.MethodInfo

CLR MethodInfo information for the Add method, or null.

Exception Condition

contentType is null.

This method should return null for cases where the XamlType for this XamlTypeInvoker is not a writeable collection or dictionary. Specifically, should return null for cases where XamlType.LookupCollectionKind returns None.

System_CAPS_security Security Note

If you are not accessing a fully trusted XAML type system, this method has the potential to report false MethodInfo information to callers.

Notes to Implementers:

The base implementation returns null for cases where a XamlTypeInvoker is based on an unknown XamlType, which includes cases where the UnderlyingType of the XamlType is null. It also returns null if XamlType.ItemType is null.

XAML collections potentially have more than one Add method, because a XAML collection can potentially support more than one content type (see AllowedContentTypes, or see ContentWrapperAttribute for information about one implementation of this concept in WPF). The default implementation uses internal logic to return the best match based on the signatures and the type of the supplied contentType.
