Unpredicted language behavior i++

I tried to do the following

i=0;
if (i++ % Max_Col_items == 0 && i !=0)
{

}

and discovered that it increased i in the middle

i % Max_Col_items == 0;
i=i+1;
i !=0;

when I though it would add increase i in the end:

i % Max_Col_items == 0;
i !=0;
i=i+1;

Can any one find explanation of how i++ works in C#?

Solution

  • i++ will give you the original value, not the incremented, You will see the change on the next usage of i. If you want to get the incremented value then use ++i.
