CollectionBase.IList.Remove Method (Object)

 

Removes the first occurrence of a specific object from the CollectionBase.

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

private abstract Remove : 
        value:Object -> unit
private override Remove : 
        value:Object -> unit

Parameters

value
Type: System.Object

The Object to remove from the CollectionBase.

Exception Condition
ArgumentException

The value parameter was not found in the CollectionBase object.

NotSupportedException

The CollectionBase is read-only.

-or-

The CollectionBase has a fixed size.

If the CollectionBase does not contain the specified object, the CollectionBase remains unchanged. No exception is thrown.

This method performs a linear search; therefore, this method is an O(n) operation, where n is Count.

This method determines equality by calling Object.Equals.

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 into buckets, such as a hash table.

Notes to Implementers:

This method calls OnValidate, OnRemove, and OnRemoveComplete.

The following code example implements the CollectionBase class and uses that implementation to create a collection of Int16 objects.

No code example is currently available or this language may not be supported.
