Expand a random range from 1–5 to 1–7
... subtracting 4 would make it (-3...21), but in this case it becomes (1, 6, 11, 16, 21), so the end points are correct but there are four big holes: (2..5), (7..10), (12..15), (17..21). Finally you do mod 7 and add 1, giving (2, 7, 5, 3, 1). So neither 4 nor 6 ever occur. But (see above shortcut) we ...

Why should I avoid using Properties in C#?

write-only; field access is always
readable and writable.
This is a win for properties, since you have more fine-grained control of access.
A property method may throw an
exception; field access never throws
an exception.
While this is mostly true, you can very well call a method on...
