Gets an ICollection containing the keys of the IDictionary.

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

private abstract Keys : ICollection with get
private override Keys : ICollection with get

Property Value

Type: System.Collections.ICollection

An ICollection containing the keys of the IDictionary.

The keys in the returned ICollection are sorted according to the Comparer property and are guaranteed to be in the same order as the corresponding values in the ICollection returned by the Values property.

Getting the value of this property is an O(1) operation.

The following code example shows how to use the IDictionary<'TKey, 'TValue>.Keys property of the System.Collections.IDictionary interface with a SortedDictionary<'TKey, 'TValue>, to list the keys in the dictionary. The example also shows how to enumerate the key/value pairs in the dictionary; note that the enumerator for the System.Collections.IDictionary interface returns DictionaryEntry objects rather than KeyValuePair<'TKey, 'TValue> objects.

The code example is part of a larger example, including output, provided for the IDictionary.Add method.
