大家能不能帮我解释一下这个程序吗？
本人在学习c#中，希望大家指导。能每条语句都解释一下吗？
using System;
class MyClass
{
 public MyClass() {
  Console.WriteLine("Constructor");
 }
 public MyClass(int value) {
  MyField = value;
  Console.WriteLine("Constructor");
 }
 ~MyClass() {
  Console.WriteLine("Destructor");
 }
 public const int MyConstant = 12;
 public int MyField = 34;
 public void MyMethod(){
  Console.WriteLine("MyClass.MyMethod");
 }
 public int MyProperty {
  get {
   return MyField;
  }
  set {
   MyField = value;
  }
 }
 public int this[int index] {
  get {
   return 0;
  }
  set {
   Console.WriteLine("this[{0}] was set to {1}", index, value);
  }
 }
 public event EventHandler MyEvent;
 public static MyClass operator+(MyClass a, MyClass b) {
  return new MyClass(a.MyField + b.MyField);
 }
 internal class MyNestedClass
 {}
}
