The Middle-Square Method of (pseudo)random number generation was first suggested by John Von Neumann in 1946 and is defined as follows:
Rn+1 = mid((Rn)2, m)
For example:

Is there any static function of Random class to do the same? like...
Random.Next(1,100);
I don't want to create an instance unnecessaril…
