What exactly do you want? First you mention "maximum", then you have
a problem with a "duplicate" number...

For "maximum":
the Next() method has several overloads. Some of them specify a range
for the result (usually: including the lower limit, excluding the upper limit).
An upper limit of 0 seems strange ...

For "duplicate":
The random number is *random*, there should be no (apparent) relation
between the number returned now and numbers returned previously.
This doesn't mean "no identical numbers", it means "no check for duplication".
Duplicate numbers /can/ happen. What do you want to happen when you
try to read 7 distinct integer values in the range 1 to 6?
