Keys Property

[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Gets an ICollection containing the keys in the Hashtable.

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

Syntax

'Declaration
Public ReadOnly Property Keys As ICollection
public ICollection Keys { get; }
public:
virtual property ICollection^ Keys {
    ICollection^ get () sealed;
}
abstract Keys : ICollection with get
override Keys : ICollection with get
final function get Keys () : ICollection

Property Value

Type: System.Collections. . :: . .ICollection
An ICollection containing the keys in the Hashtable.

Implements

IDictionary. . :: . .Keys

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 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.
