Comparing two instances of a class

Question

I have a class like this

public class TestData
{
   public string Name {get;set;}
   public string type {get;set;}

   public List Members = ne         


        

Answer 1

One way of doing it is to implement IEquatable

public class TestData : IEquatable
{
   public string Name {get;set;}
   public string type {get;set;}

   public List Members = new List();

   public void AddMembers(string[] members)
   {
      Members.AddRange(members);
   }

   public bool Equals(TestData other)
   {
        if (this.Name != other.Name) return false;
        if (this.type != other.type) return false;

        // TODO: Compare Members and return false if not the same

        return true;
   }
}


if (testData1.Equals(testData2))
    // classes are the same

You can also just override the Equals(object) method (from System.Object), if you do this you should also override GetHashCode see here
