C# anonymous object (javascript like) for adhoc usage. No class definition

Question

I wanted to create an anonymous C# object with no class definition. Similar to javascript object. Sample code not working:

var data = new
  {
    groups = new object[] {
      new {
        header = "Facebook",
        buttons = new object[] {
          new {
            label = "Create new post"
          }
        }
      }
    }
  };

I was about to ask and found it out myself. So just wanted to share the solution. — nest

Than you should either delete your question or write it in a manner that helps the community. But with your current question there is no chance to help ypu out on this topic. Since the problem was a simple typo I vote for closing this question. — MakePeaceGreatAgain

For me it is more of a conceptual mistake, not a typo. I actually thought this was the correct way — nest

It actually helped me. I found it by googling adhoc object c# and got this question. I'm rewriting it to confirm with SO guidelines. — Cornelius Roemer

The problem was the new object[]. It is just new []. Working code:

var data = new
  {
    groups = new [] {
      new {
        header = "Facebook",
        buttons = new [] {
          new {
            label = "Create new post"
          }
        }
      }
    }
  };
