IDictionary<TKey,TValue>.Keys Property

Definition

Gets an ICollection<T> containing the keys of the IDictionary<TKey,TValue>.

public:
 property System::Collections::Generic::ICollection<TKey> ^ Keys { System::Collections::Generic::ICollection<TKey> ^ get(); };
public System.Collections.Generic.ICollection<TKey> Keys { get; }
member this.Keys : System.Collections.Generic.ICollection<'Key>
Public ReadOnly Property Keys As ICollection(Of TKey)

Property Value

ICollection<TKey>

An ICollection<T> containing the keys of the object that implements IDictionary<TKey,TValue>.

Examples

The following code example shows how to enumerate keys alone using the Keys property.

This code is part of a larger example that can be compiled and executed. See System.Collections.Generic.IDictionary<TKey,TValue>.

// To get the keys alone, use the Keys property.
icoll = openWith->Keys;

// The elements of the ValueCollection are strongly typed
// with the type that was specified for dictionary values.
Console::WriteLine();
for each( String^ s in icoll )
{
    Console::WriteLine("Key = {0}", s);
}
// To get the keys alone, use the Keys property.
icoll = openWith.Keys;

// The elements of the ValueCollection are strongly typed
// with the type that was specified for dictionary values.
Console.WriteLine();
foreach( string s in icoll )
{
    Console.WriteLine("Key = {0}", s);
}
' To get the keys alone, use the Keys property.
icoll = openWith.Keys

' The elements of the ValueCollection are strongly typed
' with the type that was specified for dictionary values.
Console.WriteLine()
For Each s As String In  icoll
    Console.WriteLine("Key = {0}", s)
Next s

Remarks

The order of the keys in the returned ICollection<T> is unspecified, but it is guaranteed to be the same order as the corresponding values in the ICollection<T> returned by the Values property.
