c# code

there is a small prob with the code converted from vb to c#
---------visual basic ------------
dim j as integer
dim i as integer
for i =0 to 5
j = 2 ^ i    (i being 0 in first time loop)

msgbox(j) returns 1 (ie 2 ^ 0)  

next

==============cSharp========================I want this to return 1 same as in vb

but same code in C# msgbox(j) returns 2
int j = 0;

  for (int i = 0; i < 5; i++)
    {
       j = 2 ^ i;
      Messagebox.show(j); -- j returns 2 (ie  2 ^ 0)

    }
