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
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.
