IOrderedDictionary.RemoveAt Method (Int32)

 

Removes the element at the specified index.

Namespace:   System.Collections.Specialized
Assembly:  System (in System.dll)

abstract RemoveAt : 
        index:int -> unit

Parameters

index
Type: System.Int32

The zero-based index of the element to remove.

Exception Condition
ArgumentOutOfRangeException

index is less than 0.

-or-

index is equal to or greater than Count.

NotSupportedException

The IOrderedDictionary collection is read-only.

-or-

The IOrderedDictionary collection has a fixed size.

In collections of contiguous elements, such as lists, the elements that follow the removed element move up to occupy the vacated spot. If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does not apply to collections where elements are conceptually grouped together, such as a hash table.

The following code example demonstrates the implementation of a simple IOrderedDictionary based on the ArrayList class. The implemented IOrderedDictionary stores first names as the keys and last names as the values, with the added requirement that each first name is unique. This code is part of a larger code example provided for the IOrderedDictionary class.
