Java Map equivalent in C#

Question

I\'m trying to hold a list of items in a collection with a key of my choice. In Java, I would simply use Map as follows:

class Test {
  Map         


        

Answer 1

class Test
{
    Dictionary entities;

    public string GetEntity(int code)
    {
        // java's get method returns null when the key has no mapping
        // so we'll do the same

        string val;
        if (entities.TryGetValue(code, out val))
            return val;
        else
            return null;
    }
}
