bool ICollection<KeyValuePair<TKey, TValue>>.Remove(
    KeyValuePair<TKey, TValue> item
)

Parameters

item
Type: System.Collections.Generic..::.KeyValuePair<(Of <(TKey, TValue>)>)
The object to remove from the dictionary.

Return Value

Implements

ICollection<(Of <(T>)>)..::.Remove(T)

Exceptions

Remarks

This member is an explicit interface member implementation. It can be used only when the ReadOnlyDictionary<(Of <(TKey, TValue>)>) instance is cast to an ICollection<(Of <(T>)>) interface. The ICollection<(Of <(T>)>) interface specifies that the Remove method should throw a NotSupportedException exception if the collection that implements the interface is read-only.
