override this.DeleteLink : obj * string * obj -> unitPublic Overridable Sub DeleteLink (source As Object, sourceProperty As String, target As Object)Parameters
- source
- Object
The source object in the link to be marked for deletion.
- sourceProperty
- String
The name of the navigation property on the source object that is used to access the target object.
- target
- Object
The target object involved in the link that is bound to the source object. The target object must be of the type identified by the source property or a subtype.
Exceptions
When source, sourceProperty, or target is null.
Remarks
Notifies the context that a link exists between the source and target object and that the link is represented via the source.sourceProperty which is a collection. The context adds this link to the set of deleted links to be sent to the data service on the next call to SaveChanges(). If the specified link exists in the "Added" state, then the link is detached (see DetachLink method) instead.
