Introduction

StuceSoftware.RandomStringGenerator is a library developed in C# to generate random strings of from various categories. It is fast and suports string generation of various length. It is parameterized to generate both a single or a list of random strings.
Random strings can be of types lowercase, uppercase, numbers and symbols. It also allows you to generate random string with only a subset of symbols from the supported list. It is an ideal library for use in projects such as:

• password generator
• unique-id generator
• unique filename generator
• raw data generator for data processing/parsing projects
• etc. etc.

Features

• Supports single or multiple random string generation
• Supports random string generation from alphabet, numbers, symbols or a combination of them
• Supports customized length of random string
• Supports random length of generated strings with a fixed max length
• Supports true unique random number generation
• Support force inclusion of strings of each type
• Supports .NET Standard 2.0 & 2.1, .NET 6.0, 8.0 & 9.0

Supported Types

• Lowercase : abcdefghijklmnopqrstuvwxyz
• Uppercase : ABCDEFGHIJKLMNOPQRSTUVWXYZ
• Numbers : 0123456789
• Symbols : !#$%&'()*+,-./:;<=>?@[]^_`{|}~"

These types are defined by an enum CharClasses which has the [Flags] attribue, making it easy to combine the different classes.

Breaking Changes 🚨

v2.0

Switched to a [Flags] enum for CharClasses

v3.0 (in pre-release)

RandomStringGenerator class is now non-static. The constructor takes an IRandomSource object, which is used internally to generate random values.
There are two implementations of IRandomSource provided with the library: SystemRandomSource and SecureRandomSource.

Download and Install

NuGet Package StuceSoftware.RandomStringGenerator

dotnet add package StuceSoftware.RandomStringGenerator

Sample Usage

using StuceSoftware.RandomStringGenerator;
using StuceSoftware.RandomStringGenerator.RandomSourceImplementations;

var randomStringGenerator = new RandomStringGenerator(new SystemRandomSource());

// generating one random string from lowercase alphabets
var randomString = randomStringGenerator.GetString(CharClasses.Lowercase);
System.Console.WriteLine(randomString);

// generating 100 random strings using both upper and lower case alphabet, numbers and all supported symbols
var randomAlphaNumbericStrings = randomStringGenerator.GetStrings(
    CharClasses.Lowercase | CharClasses.Uppercase | CharClasses.Numbers | CharClasses.Symbols, 100);
foreach (string s in randomAlphaNumbericStrings)
    System.Console.WriteLine(s);

// generating 200 random string using uppercase alphabet and custom symbols
var randomAlphabetWithCustomSymbols = randomStringGenerator.GetStrings(CharClasses.Uppercase, 200, "/+*-");
foreach (string s in randomAlphabetWithCustomSymbols)
    System.Console.WriteLine(s);

// generating 1000 true random strings of length 20 using uppercase alphabet with custom symbols
var trueUniqueRandomStrings = randomStringGenerator.GetStrings(CharClasses.Uppercase, 1000, 20, "/+*-", false, true);
foreach (string s in trueUniqueRandomStrings)
    System.Console.WriteLine(s);

// generating 100 random strings using both upper and lowercase alphabet, numbers and custom symbols
var randomAlphabetWithCustomSymbols = randomStringGenerator.GetStrings(CharClasses.Lowercase | CharClasses.Uppercase | CharClasses.Numbers, 100, "/+*-", forceOccuranceOfEachType: true);
foreach (string s in randomAlphabetWithCustomSymbols)
    System.Console.WriteLine(s);

Note 👀
As of version 2.0, if custom symbols are defined, there is no need to specify the symbol character class (CharClasses.Symbols), this is assumed when custom symbols are provided
