I can't believe my eyes!
Here is a simple test:
struct A
{
public int X;
public int Y;
}
public class Program
{
public static void Main()
{
A a, b, c;
a = b = new A { X = 3, Y = 5 };
c = a;
a.X = 8;
Debug.Print("A: X=" + a.X + "; Y=" + a.Y);
Debug.Print("B: X=" + b.X + "; Y=" + b.Y);
Debug.Print("C: X=" + c.X + "; Y=" + c.Y);
Debug.Print("");
Debug.Print("A==A =" + a.Equals(a));
Debug.Print("B==B =" + b.Equals(b));
Debug.Print("C==C =" + c.Equals(c));
Debug.Print("");
Debug.Print("A==B =" + a.Equals(b));
Debug.Print("A==C =" + a.Equals(c));
Debug.Print("B==C =" + b.Equals(c));
Debug.Print("");
Debug.Print("");
int r, s, t;
r = s = 555;
t = r;
r = 333;
Debug.Print("R=" + r);
Debug.Print("S=" + s);
Debug.Print("T=" + t);
Debug.Print("");
Debug.Print("R==S =" + (r == s));
Debug.Print("R==T =" + (r == t));
while (true)
{
Thread.Sleep(1000);
}
}
}
The result is the following (Netduino Plus 2; NetMF 4.2):
A: X=8; Y=5
B: X=8; Y=5
C: X=3; Y=5
A==A =False
B==B =False
C==C =False
A==B =False
A==C =False
B==C =False
R=333
S=555
T=555
R==S =False
R==T =False
The R-S-T integer test is just for comparison, but behaves fine.
The same snippet ran on regular desktop .Net produces the following (correct) result:
A: X=8; Y=5
B: X=3; Y=5
C: X=3; Y=5
A==A =True
B==B =True
C==C =True
A==B =False
A==C =False
B==C =True
R=333
S=555
T=555
R==S =False
R==T =False
Anyone may explain all that???
