IDictionary.Remove Method

When implemented by a class, removes the element with the specified key from the IDictionary.

[Visual Basic]
Sub Remove( _
   ByVal key As Object _
)
[C#]
void Remove(
   object key
);
[C++]
void Remove(
   Object* key
);
[JScript]
function Remove(
   key : Object
);

Parameters

key
The key of the element to remove.

Exceptions

Exception Type Condition
ArgumentNullException key is a null reference (Nothing in Visual Basic).
NotSupportedException The IDictionary is read-only.

-or-

The IDictionary has a fixed size.

Remarks

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 hashtable.
