There's a .NET forum here too, where this post might have gotten a quicker response. Anyway, have you read the Help topics on operator overloading? How have they explained it to you in the C# class that you're taking? I've not actually done any operator overloading, but it seems pretty straightforward. I found some examples in the Help, here's an example of an overloaded + operator in a struct (could be used in a class as well, like your Hand class):
public struct Complex 
{
   public int real;
   public int imaginary;

   public Complex(int real, int imaginary) 
   {
      this.real = real;
      this.imaginary = imaginary;
   }

   // Declare which operator to overload (+), the types 
   // that can be added (two Complex objects), and the 
   // return type (Complex):
   public static Complex operator +(Complex c1, Complex c2) 
   {
      return new Complex(c1.real + c2.real, c1.imaginary + c2.imaginary);
   }
   // Override the ToString method to display an complex number in the suitable format:
   public override string ToString()
   {
      return(String.Format("{0} + {1}i", real, imaginary));
   }
This should maybe get you started.

I'm trying to overload the + operator of the Hand class so that I can get a card from the deck array into the hand array. This is a requirement of the lab, not something I decided to do on my own.
