How to create a HashTable in C# with multiple keys and values

I need to implement in C# the following structure from ActionScript3:

objectArray.push({name:"Stx10",category:123 , isSet:false, isEmpty:true});

So that later I can access the objects from the array like this:

String name =objectArray[i].name

So I naturally though about C Sharp Hash Tables but the allow only a single Key -> Value insertion. I can't believe .NET framework has not solution for such a thing... Any help will be greatly appreciated!

It looks to me like you're pushing a custom type to an array.

Using an IList will give you a quick Add method in which you can pass a new object of you type such as:

IList<MyType> myCollection = new List<MyType>();

myCollection.Add(new MyType{
Name = "foo",
Category = "bar",
IsSrt = true,
IsEmpty = true
});

UPDATE

Just to add a bit of extra value based on Henk's comment on Porges's answer, here's a way to do the same thing using a dynamic type and thus removing the need for a custom type:

IList<dynamic> myCollection  = new List<dynamic>();
    myCollection.Add(new {  
      Name = "foo",
      Category = "bar",
      IsSet = true,
      IsEmpty = true});

Don't forget about 

  var d=new Dictionary<string, object>();

What's your intention though?

If you're just accessing elements by index as in your example, then you don't need hashed access, you can just use a List<T>.

I'd encapsulate your information into a type like this:

class Thing {
    public string Name {get; set;}
    public int Category {get; set;}
    public bool IsSet {get; set;}
    public bool IsEmpty {get; set;}
}

Then:

objectList.Add(new Thing{Name="Stx10", Category=123, IsSet=false, IsEmpty=true})

// ...

string name = objectList[i].Name;
