PNRG algorithm implementation in PHP and C#

I've created a procedural image generator that uses the default PNRG built in PHP5.

I can set the seed with mt_srand($id); and get always the same numbers sequence (with mt_rand(0,255);).

---

What I need:

a PNRG implementation that will work the exact same way in PHP and C#

---

Example:

PHP:

mt_srand(123);
echo mt_rand(0,255); //returns 34
echo mt_rand(0,255); //returns 102
echo mt_rand(0,255); //returns 57
echo mt_rand(0,255); //returns 212
echo mt_rand(0,255); //returns 183

C#:

setSeed(123);
print getRand(0,255); //returns 34
print getRand(0,255); //returns 102
print getRand(0,255); //returns 57
print getRand(0,255); //returns 212
print getRand(0,255); //returns 183
