public virtual void Remove (string name);

public virtual void Remove (string? name);

Public Overridable Sub Remove (name As String)

Parameters

name: String

The String key of the entry to remove. The key can be null.

Exceptions

NotSupportedException

The collection is read-only.

Remarks

If the NameValueCollection doesn't contain an element with the specified key, the NameValueCollection remains unchanged. No exception is thrown.

If you specify a null value to the name parameter, an entry with a null key is removed, if found.

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.

This method is an O(n) operation, where n is Count.
