C# - How can I call a method from another 'class ClassName where T : IComparable'

Question

In my 'Program.cs' I am trying to call method 'inOrder()' from another class 'BinTree.cs'.

Class BinTree starts with class BinTree<T> where T : IComparable

I've tried:

inOrder();

and

BinTree<T>.inOrder();

and

BinTree<int>.inOrder();

But none of these work.

Thanks for looking.

EDIT:

class Program
{
    static void Main(string[] args)
    {
        Node<int> tree = new Node<int>(6);
        tree.Left = new Node<int>(2);
        tree.Left.Right = new Node<int>(5);

        tree.Left.Right.Data = 3;

        tree.Right = new Node<int>(8);



        (new BinTree<int>()).inOrder();

    }

EDIT2:

    private Node<T> root;
    public BinTree()  //creates an empty tree
    {
        root = null;
    }
    public BinTree(Node<T> node)  //creates a tree with node as the root
    {
        root = node;
    }

If `inOrder` is an instance method, you need to create an instance first. If it's static, it needs to be public, in which case `BinTree.inOrder();` should work. — Mike Christensen, Aug 06 '14 at 17:01
'inOrder()' is declared in class BinTree. 'public void inOrder() { inOrder(root); }' — BoggartBear, Aug 06 '14 at 17:02
Hmm that runs but now it is not using my tree which I'll post the code for above. — BoggartBear, Aug 06 '14 at 17:09
Do you have some sort of mechanism to add `Node` objects to a `BinTree` instance? — Mike Christensen, Aug 06 '14 at 17:13
EDIT2 in top post. I'm new to all this so bare with me sorry. — BoggartBear, Aug 06 '14 at 17:18

From what I can tell, you need to create a BinTree<int> instance and pass in your Node<int> instance on the constructor. Something like this:

class Program
{
    static void Main(string[] args)
    {
        // Create Node instances for tree
        Node<int> node = new Node<int>(6);
        node.Left = new Node<int>(2);
        node.Left.Right = new Node<int>(5);
        node.Left.Right.Data = 3;
        node.Right = new Node<int>(8);

        // Create tree, set root node
        BinTree<int> tree = new BinTree<int>(node);
        tree.inOrder(); // Call inOrder method of tree instance
    }
}

Worked a treat, thank you. Now I'll try and figure out why because my assigned work just says 'the user would call 'tree.inOrder();'. – BoggartBear Aug 06 '14 at 17:40
