How is the ‘random’ function used in C#?
In C#, the Random class is used to generate pseudo-random numbers. Below are the common methods and usage of the Random class.
- Instantiate a Random object:
- Create a new instance of Random called rand.
- Generate random integers:
- – Generate a random non-negative integer.
– Generate a random integer within a specified range. - Generate random floating-point numbers.
- Generate a random floating point number within the range [0, 1) and Generate a random floating point number within a specified range.
- Generate random bytes:
- Generate a random array of bytes with a specified length.
- Mix up the order of the list.
- Sort the list using random numbers to achieve a randomized arrangement.
Please note that the Random class uses the system time as a seed value, so creating Random objects within a loop may result in generating the same random number sequence. To address this issue, you can create a Random object when the application starts and reuse it whenever you need random numbers.
