vb.net to get the random number within a specified range __.net

Recently need to do a random sampling of the small program, studied the vb.net under the random number of methods:

First, we do a trial, using the Rnd () function +math.round (), for example, I would like to take a random number within 1-100 (the result should probably contain 1 and 100)

Math.Round (Rnd () * 100)

Did a 1000 cycle sampling, found that the result contains 0-100 of the possible, but the random out of the 0 is not the result I want, and then replace the following more convenient way to achieve:

Dim myrnd as New Random
myrnd.next (1, 101)

After instantiating a random object, using the next (A,b) method to take random numbers, where the random results from a to b-1 may be, so to achieve 1-100 random, you should use Next (1,101) on it, or do a 1000 times cycle test, the results meet the demand ~
