How do I atomically swap 2 ints in C#?

Question

What (if any) is the C# equivalent of the x86 asm xchg instruction?

With that command, which imo is a genuine exchange (unlike Interlocked.Exchange), I

Answer 1

Outside of Interlocked.Exchange, I'm assuming the XCHG command is probably an implementation of the XOR Swap, so you could write your own.

C syntax: (from wikipedia link)

 void xorSwap (int *x, int *y) {
     if (x != y) {
         *x ^= *y;
         *y ^= *x;
         *x ^= *y;
     }
 }

Edit this is not atomic, you would have to synchronize it yourself
