Multidimensional associative array in asp

I have been trying to find the awnser to this for a while. I am converting a site from php to asp. I have an array like this.

$students = array(

    array(
        "id" => "1",
        "name" => "John",
        "group" => "A"
    ),
    array(
        "id" => "2",
        "name" => "Joe",
        "group" => "A"
    ),
    array(
        "id" => "3",
        "name" => "Derp",
        "group" => "B"
    ),
);

foreach($student as $slacker){
    //use the data
}

Is there any alternative that even comes close to this with asp?

You can make a class and use generic list to hold the array of your class type.

public class YourGroup
{
   public string id { get; set; };
   public string name { get; set; };
   public string group { get; set; };       
}

List<YourGroup> lstGroup = new List<YourGroup>();
lstGroup.Add(new YourGroup(id ="1", name="Jon", group="A1"));
lstGroup.Add(new YourGroup(id ="2", name="Jon", group="A2"));
lstGroup.Add(new YourGroup(id ="3", name="Jon", group="A3"));
string idOfFirst lstGroup[0].id;

You might be looking for what is called a dictionary. While its not quite deep nested like $myArray['foo']['bar'] the dictionary will allow you to stuff like

 Dictionary<int, MyObject> myDictionary = new Dictionary<int, MyObject>();

where your MyObject holds the following object

 class MyObject
 {
      public string name;
      public string group;
 }

as a result you can traverse it as such

MyObject foo = new MyObject();

foo.name = "tada!";
foo.group = "foo";

myDictionary.add(1, foo);

foreach (MyObject obj in Dictionary.Values)
{
     //Do Stuff
}

a completely string associated array would be

 Dictionary<string, string> myDictionary = new Dictionary<string, string>();

 string something = myDictionary["value"];
