A small program that parses expressions and evaluates them using LINQ Expressions
using System.Collections.Generic;
using System.Linq.Expressions;

namespace TinyLisp {

    // a shared base class for ExpressionNode and IntNode
    public abstract class CodeNode {

        // will be used to display it in the treeview
        public abstract string Text { get; }

        // list of children (needs to be property for the WPF TreeView to bind to it) 
        private List<CodeNode> _Operands = new List<CodeNode>();
        public List<CodeNode> Operands { get { return _Operands; } }
