System.Collections.Hashtable.Keys Property

Gets an ICollection containing the keys in the Hashtable.

Syntax

public virtual ICollection Keys { get; }

Value

A ICollection containing the keys of the current instance.

Remarks

The order of the keys in the ICollection is unspecified, but it is the same order as the associated values in the ICollection returned by the Hashtable.Values method.

The returned ICollection is not a static copy; instead, the ICollection refers back to the keys in the original Hashtable. Therefore, changes to the Hashtable continue to be reflected in the ICollection.

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