This is the tenth and final in a series of quick how-to articles on ReSharper. There are obviously many more awesome features to explore, but I want to give equal time to the other available productivity tools for Visual Studio. Next week I will be starting a new series of tips on Telerik JustCode. Following that series, I will take a look at DevExpress CodeRush.

Tip #10 – Generate Equality Members

Use: If you are creating a class that will need to participate in equality operations, ReSharper can quickly generate the necessary method implementations for you.

Before

   1:      public class Order : IOrder

   2:      {

   3:          public int OrderId { get; set; }

4:

   5:          public int CustomerId { get; set; }

6:

   7:          public DateTime OrderDate { get; set; }

8:

   9:          public IList<OrderDetail> OrderDetails { get; set; }

  10:      }

Click Generate Code

Select Equality Members

Select options and finish

After

   1:      public class Order : IOrder, IEquatable<Order>

   2:      {

   3:          public int OrderId { get; set; }

4:

   5:          public int CustomerId { get; set; }

6:

   7:          public DateTime OrderDate { get; set; }

8:

   9:          public IList<OrderDetail> OrderDetails { get; set; }

10:

  11:          public bool Equals(Order other)

  12:          {

  13:              if (ReferenceEquals(null, other)) return false;

  14:              if (ReferenceEquals(this, other)) return true;

  15:              return other.OrderId == OrderId;

  16:          }

17:

  18:          public override bool Equals(object obj)

  19:          {

  20:              if (ReferenceEquals(null, obj)) return false;

  21:              if (ReferenceEquals(this, obj)) return true;

  22:              if (obj.GetType() != typeof (Order)) return false;

  23:              return Equals((Order) obj);

  24:          }

25:

  26:          public override int GetHashCode()

  27:          {

  28:              return OrderId;

  29:          }

30:

  31:          public static bool operator ==(Order left, Order right)

  32:          {

  33:              return Equals(left, right);

  34:          }

35:

  36:          public static bool operator !=(Order left, Order right)

  37:          {

  38:              return !Equals(left, right);

  39:          }

  40:      }

Happy coding!
