公共属性 Item[ ( [ ( Int32] ) ] ) Gets an ExtendedProperty object in the collection by index number.
公共属性 Item[ ( [ ( String] ) ] ) Gets an ExtendedProperty object in the collection by name.
公共属性 Parent Gets the SqlSmoObject object that is the parent of the ExtendedPropertyCollection object.
公共属性 SyncRoot Gets an object that can be used to synchronize access to the collection. (从 SmoCollectionBase 继承。)
