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();
