C# object creator

Question

In javascript, I often use something like this object creator

  var o = new Object(); // generic object
  var props = { color:"red",value:5 }; // hashtable
  for(var key in props) o[key] = props[key];
  alert(o.color); //red

Can it be written as C# method with this declaration?

  static void properties(out Object o, HashTable h) { ...

Is this some design pattern? Am I inventing wheel?

Answer 1

You may want to look at the Expando Object in C# 4. That is about as close as you are going to get to a dynamic object in C# like you can get in JavaScript.

Answer 2

        var test = new { name = "Testobj", color = Colors.Aqua };
        MessageBox.Show(test.name);

It's called a anonymous Type, I think this is what you are searching for.

Answer 3

Since c# is statically typed, you cannot achieve this.. closest possible is anonymous methods

Dictionary<string,int> dic=new Dictionary<string,int>();
            dic.Add("red", 5);
            dic.Add("black", 10);
            dic.Add("white", 1);
            object[] obj;
            foreach(var o in dic)
            {
                var sam= new { color = o.Key,value=o.Value };
                Console.WriteLine(sam.color);               

            }
