Keys Property

Hashtable.Keys Property

 

Gets an ICollection containing the keys in the Hashtable.

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

public virtual ICollection Keys { get; }

Property Value

Type: System.Collections.ICollection

An ICollection containing the keys in the Hashtable.

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 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.
