c# List.Contains() Method Returns False

Question

In the code block below I would expect dictCars to contain: { Chevy:Camaro, Dodge:Charger }

But, dictCars comes back empty. Because this line returns false each time it

Answer 1

You can add this code, by implementing IEquatable

public class Car: IEquatable
{

    ......

    public bool Equals( Car other )
    {
        return this.CarID  == other.CarID && this.CarName == other.CarName;
    }
}
