Introduction

RandomString4Net is a library developed in .NET Framework to generate N random strings of M length 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 alphabet and alphanumeric supporting all the cases viz. lower, upper and mixed.
It also supports symbol during the random string generation process. Following are the list of supported symbols
!#$%&'()*+,-./:;<=>?@[]^_`{|}~"

It also allows you to generate random string with only a subset of symbols from the above supported list. It is an ideal use for project like

password generator
mobile number generator
unique-id generator
unique filename generator
raw data generator for data processing/parsing projects
fake name generator 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 randon string
Supports random length of generated strings with a fixed max length
Supports true unique random number generation (v1.3.0)
Built with compilation conditions to take advantage of newer .NET Framework functionalities
Improved performance in newer .NET Framework ( >2.0)
Added support to force include strings of each type (version 1.4.0)
Added support for .NET (>5.0)
Added support for .NET Core (>2.2)
Added support for .NET Standard (>2.0)
Added support for RandomNumberGenerator in .NET 6.0 and higher as RNGCryptoServiceProvider is marked as obsolete
Added support for .NET 8.0

Get Started

1. Install Package

PM> Install-Package RandomString4Net

2. Add reference in your project

3. Call the methods in your program

using RandomString4Net;

namespace RandomString4NetTester
{
    public void Main()
    {
        // generating one random string from lowercase alphabets
        string randomString = RandomString.GetString(Types.ALPHABET_LOWERCASE);
        System.Console.WriteLine(randomString);

        // generating 100 random string from all mixedcase alphabet, numbers and all supported symbols
        List<string> randomAlphaNumbericStrings = RandomString.GetStrings(Types.ALPHANUMERIC_MIXEDCASE_WITH_SYMBOLS, 100);
        foreach (string s in randomAlphaNumbericStrings)
            System.Console.WriteLine(s);

        // generating 200 random string from uppercase alphabet with custom symbols
        List<string> randomAlphabetWithCustomSymbols = RandomString.GetStrings(Types.ALPHABET_UPPERCASE, 200, "/+*-");
        foreach (string s in randomAlphabetWithCustomSymbols)
            System.Console.WriteLine(s);

        // generating 1000 true random strings of length 20 from uppercase alphabet with custom symbols
        List<string> trueUniqueRandomStrings = RandomString.GetStrings(Types.ALPHABET_UPPERCASE, 1000, 20, false, true);
        foreach (string s in trueUniqueRandomStrings)
            System.Console.WriteLine(s);

        // generating 100 random string of mixedcase alphanummeric with custom symbols
        List<string> randomAlphabetWithCustomSymbols = RandomString.GetStrings(Types.ALPHANUMERIC_MIXEDCASE_WITH_SYMBOLS, 100, "/+*-", forceOccuranceOfEachType: true);
        foreach (string s in randomAlphabetWithCustomSymbols)
            System.Console.WriteLine(s);
    }
}
