How to generate random number?

Question

How can I generate random number?

Answer 1

It depends on what type of number you want to be returned; is it integer or decimal?

If you need Integer, use this:

Random r = new Random();
int randomInt = r.Next(range);

For example, you want to get a Random Integer from 0-9:

Random r = new Random();
int randomNumber = r.Next(10);

10 represents the range starting from 0.

0-9 consists of 10 numbers.

If you want a random integer from 1-10:

Random r = new Random();
int randomNumber = r.Next(10) + 1;

It will add 1 from the generated random number so the options of the random number to be returned is from 1-10.

Now, if you need a Random Decimal Number, use this:

Random r = new Random();
double randomDec = r.NextDouble();

Computers can't generate real random numbers...
