Example 1: c# interface property

interface InterfaceExample
{
    int Number { get; set; }
}

class Example : InterfaceExample
{
	int num = 0;
	public int Number { get { return num; } set { num = value; } }
}

Example 2: c# interfaces

public class Car : IEquatable<Car>
{
    public string Make {get; set;}
    public string Model { get; set; }
    public string Year { get; set; }

    // Implementation of IEquatable<T> interface
    public bool Equals(Car car)
    {
        return (this.Make, this.Model, this.Year) ==
            (car.Make, car.Model, car.Year);
    }
}
