RandEx 1.0.10

RandEx

RandEx is a library designed to provide advanced randomisation functions in C#. It provides various methods for generating random numbers, selecting random elements, shuffling collections and more.

Features

• Custom seed management: Initialize random number generation with custom seeds.
• Flexible random number generation:
  • Random integers (with various range options).
  • Random doubles (uniform distribution).
  • Random booleans.
  • Gaussian distribution: Generate random numbers according to a normal distribution.
• Advanced Utility Methods:
  • Generate random date/time objects.
  • Select random items from collections.
  • Shuffle collections.
  • Generate random colours, GUIDs, and byte arrays.
  • Enumeration support: Easily select random values from any enumeration.
• Thread-safe implementation: Each thread maintains its own state for safe and efficient concurrent use, making it suitable for multi-threaded environments.

Installation

Run dotnet add package RandEx

Example

// Import the namespace
using RandEx;

Basic Random Number Generation

// Random integer between two values
int randomInt = RandomEx.GetRandomInt(10, 50);

// Random double between 0.0 and 1.0
double randomDouble = RandomEx.GetRandomDouble();

// Random boolean
bool randomBool = RandomEx.GetRandomBool();

Deterministic Randomization with Custom Seeds

// Set a custom seed for deterministic random number generation
RandomEx.SetSeed(123456);
int deterministicRandom = RandomEx.GetRandomInt();

Gaussian Distribution

// Generate a random number with a Gaussian (normal) distribution
double randomGaussian = RandomEx.GetRandomGaussian();

Random Collection Utilities

var list = new List<int> { 1, 2, 3, 4, 5 };

// Get a random element
int randomElement = RandomEx.GetRandomElement(list);

// Shuffle the list
RandomEx.Shuffle(list);

Random DateTime

// Random DateTime between two dates
DateTime randomDate = RandomEx.GetRandomDateTime(
    new DateTime(2000, 1, 1),
    new DateTime(2020, 1, 1)
);

Random Bytes and Colors

// Generate a random byte array
byte[] randomBytes = RandomEx.GetRandomBytes(16);

// Generate a random color
var (R, G, B) = RandomEx.GetRandomByteColor();

Random Enumeration Values

enum Colors { Red, Green, Blue, Yellow }

// Get a random enum value
Colors randomColor = RandomEx.GetRandomEnumValue<Colors>();

Random Char

// Generate a char (From 'a' to 'z')
char randomChar = RandomEx.GetRandomChar('a', 'z');
// Generate a char (From '0' to '9')
char randomChar2 = RandomEx.GetRandomChar('0', '9');
// Generate a char (From ' ' to '~') default
char randomChar3 = RandomEx.GetRandomChar();
