vb中个随机选取一个0到1000之间的数怎么写

是x=Rnd*1000还是x=Rnd*1000+1 ？？

Answer 1

To produce random integers in a given range, use this formula:

Int((upperbound - lowerbound + 1) * Rnd + lowerbound)

Here, upperbound is the highest number in the range, and lowerbound is the lowest number in the range.

Note To repeat sequences of random numbers, call Rnd with a negative argument immediately before using Randomize with a numeric argument. Using Randomize with the same value for number does not repeat the previous sequence.

Rnd Function Example
This example uses the Randomize statement to initialize the random-number generator. Because the number argument has been omitted, Randomize uses the return value from the Timer function as the new seed value.

Dim MyValue
Randomize ' Initialize random-number generator.

MyValue = Int((6 * Rnd) + 1) ' Generate random value between 1 and 6.
