Hello guys, i have the following code:

Java

    private Map map;


public SomeFunction(Map<?,Integer> map, boolean acsending){
            Set mapEntrySet=map.entrySet();
        Entry entry;
}

and i'm trying to convert it to C#, i've read many topics, some suggested that the Map is equal to IDictionary in C#, but what about Set and Entry??

how could i convert it??
thanks :)

Mhm... I'm not aware of equivalent methods, but have you take a closer look to 'GetEnumerator'? There are two methods who gives you all Keys or all Values...

yes, i've just figured out that it's GetEnumerator...
Thanks :)

Hello Abdullatif

Java Map or C# IDictionary both represents a key value pair collection. In Java Map.entrySet returns the collection of these key value pairs in form of a Set which is collection with no duplicate values. The Key Value pair itself is represented by Entry which is child interface in Map. The equivalent of Map.Entry for IDictionary Interface is DictionaryEntry.

e.g. Enumerate All String values in a Map

Java

for (Map.Entry<string,> entry : mymap.entrySet())
    System.out.println("Value for Key '" + entry.getKey() + "' is " + entry.getValue());

Equivalent code in C# would be

C#

foreach (DictionaryEntry de in myDictionary)
    Console.WriteLine("Key = {0}, Value = {1}", de.Key, de.Value);
