What is the difference between == and Equals() for primitives in C#?

Question

Consider this code:

int age = 25;
short newAge = 25;
Console.WriteLine(age == newAge);  //true
Console.WriteLine(newAge.Equals(age)); //false
Console.ReadLin         


        

Answer 1

Because there is no overload for short.Equals that accepts an int. Therefore, this is called:

public override bool Equals(object obj)
{
    return obj is short && this == (short)obj;
}

obj is not a short.. therefore, it is false.
