Question

What\'s the difference between struct and class in .NET?

Answer 1

Just to make it complete, there is another difference when using the Equals method, which is inherited by all classes and structures.

Lets's say we have a class and a structure:

class A{
  public int a, b;
}
struct B{
  public int a, b;
}

and in the Main method, we have 4 objects.

static void Main{
  A c1 = new A(), c2 = new A();
  c1.a = c1.b = c2.a = c2.b = 1;
  B s1 = new B(), s2 = new B();
  s1.a = s1.b = s2.a = s2.b = 1;
}

Then:

s1.Equals(s2) // true
s1.Equals(c1) // false
c1.Equals(c2) // false
c1 == c2 // false

So, structures are suited for numeric-like objects, like points (save x and y coordinates). And classes are suited for others. Even if 2 people have same name, height, weight..., they are still 2 people.
