Question

if i have reference type object, and i created two objects with the same attributes
will they have the same hash code?

sample class:

class Person
{
   int id;
   string name;

   public Person(int pid, string pname)
   {
      this.id = pid;
      this.name = pname;
   }
}

then defining two objects:

Person p1 = new Person(1,"xxx");
Perdon p2 = new Person(1,"xxx");

//p1.GetHashCode() = p2.GetHashCode() ??

Edit:i tried this code and got differnt result but testing the thing on strings gave me the same result
that why i’m asking

Answer 1

You are responsible for implementing GetHashCode yourself. If you don’t do that, they won’t have the same hash code although they should.
