Drop-in replacement for System.Random that gets more random data from Cryptographic Service Provider.


Works exactly like System.Random, except you may want to dispose of it when you are done. (If you don't dispose of it, the destructor will do it for you upon garbage collect.)

var rnd = new Tedd.MoreRandom.Random();
var dice = rnd.Next(1, 7); // A random number between 1 and 6 inclusive

Or with using:

using (var rnd = new Tedd.MoreRandom.Random()) {
	var percent = rnd.NextDouble() * 100;
	Console.WriteLine($"You are {percent}% done, please wait...");

Note that it is recommended to create a shared Random object, and in case of multiple threads use synchronized access to generate random data.

public static class Main {
	public static Tedd.MoreRandom.Random Rnd = new Tedd.MoreRandom.Random();

	public static void Start() {
		int dice;
		lock (Rnd)
			dice = Rnd.Next(1, 7); // A random number between 1 and 6 inclusive

Thread safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.


System.Random is based on so called "pseudorandom" algorithm. This means that given a seed (default: number of milliseconds since computer was started) math is used to generate seemingly random numbers. If given the same seed, a sequence of random numbers will look the same every time. For most cases this is fine, but in some cases you need more random data. One such case is cryptography, where a pseudorandom generator such as System.Random would generate a predictable sequence of numbers.

RNGCryptoServiceProvider through RandomNumberGenerator provides "cryptography grade random" numbers. These numbers are a bit more random as they are provided by the operating system, which has methods of collecting random data.

RandomNumberGenerator gives you a bunch of random bytes. It's up to you to convert to a number and size for whatever purpose. System.Random however has a simple interface, for example rnd.Next(10).

This is where MoreRandom comes in. Tedd.MoreRandom.Random mimics System.Random and is a drop-in replacement. You get the power of RandomNumberGenerator with the ease of System.Random.
