La propiedad OrderedDictionary.Keys se utiliza para obtener un objeto ICollection que contiene las claves de la colección OrderedDictionary.
Sintaxis:
public System.Collections.ICollection Keys { get; }
Valor devuelto: Devuelve un objeto ICollection que contiene las claves de la colección OrderedDictionary.
A continuación se dan algunos ejemplos para entender la implementación de una mejor manera:
Ejemplo 1:
// C# code to get an ICollection
// containing the keys in OrderedDictionary
using System;
using System.Collections;
using System.Collections.Specialized;
class GFG {
// Driver method
public static void Main()
{
// Creating a orderedDictionary named myDict
OrderedDictionary myDict = new OrderedDictionary();
// Adding key and value in myDict
myDict.Add("key1", "value1");
myDict.Add("key2", "value2");
myDict.Add("key3", "value3");
myDict.Add("key4", "value4");
myDict.Add("key5", "value5");
// Getting an ICollection containing
// the keys in OrderedDictionary
ICollection keyCollection = myDict.Keys;
// Creating a String array
String[] myKeys = new String[myDict.Count];
// Copying the OrderedDictionary elements to
// a one-dimensional Array object at the
// specified index.
keyCollection.CopyTo(myKeys, 0);
for (int i = 0; i < myDict.Count; i++) {
Console.WriteLine(myKeys[i]);
}
}
}

myDict.Add("B", "Banana");
myDict.Add("C", "Cat");
myDict.Add("D", "Dog");
// Getting an ICollection containing
// the keys in OrderedDictionary
ICollection keyCollection = myDict.Keys;
// Creating a String array
String[] myKeys = new String[myDict.Count];
// Copying the OrderedDictionary elements to

keyCollection.CopyTo(myKeys, 0);
for (int i = 0; i < myDict.Count; i++) {
