Get a count of items with a certain condition within a StackPanel's Children
===

I have an custom `UserControl` I created

    public class MyObject : UserControl
    {
        public MyObject()
        {

        }
        public bool IsFinished { get; set; }
    }

I added lets say 10(will be dynamic) `MyObject`'s to a StackPanel and every other item i set `IsFinished` to true.

    private void DoSomething()
    {
        StackPanel panel = new StackPanel();
        for (int i = 0; i <= 10; i++)
        {
            int rem = 0;
            Math.DivRem(i, 2, out rem);
            MyObject newObj = new MyObject();
            if (rem == 0)
            {
                newObj.IsFinished = true;
            }
            panel.Children.Add(newObj);
        }
    }

Now I can add the following and get the answer I am looking for (5)

    int FinishedItems = 0;
    foreach (object o in panel.Children)
    {
        if (o.GetType() == typeof(MyObject))
        {
            if (((MyObject)o).IsFinished)
            {
                FinishedItems++;
            }
        }
    }

2 Questions: 

A. Is there a more eloquent way? maybe with `Linq` I'm still learning how to use that. From what I understand, that is what LINQ technically does. 

B. Am I wrong about LINQ?
