About ShortId 📜

ShortId is a lightweight and efficient C# library designed to generate completely random, short, and unique identifiers. These IDs are perfect for use as primary keys, unique identifiers, or any scenario where you need a compact, random string. 🎯

What sets ShortId apart is its flexibility—you can specify the length of the IDs (between 8 and 15 characters) and customize the character set. It’s also thread-safe, making it ideal for high-performance applications that require generating millions of unique IDs across multiple threads. 💪

Getting Started 🚀

Installation 📦

You can add ShortId to your project using one of the following methods:

Package Manager

Install-Package shortid

.NET CLI

dotnet add package shortid

PackageReference

<PackageReference Include="shortid" />

---

Usage 🛠️

Add the Namespace

First, include the ShortId namespace in your code:

using shortid;
using shortid.Configuration;

Generate a Random ID

To generate a random ID of default length (between 8 and 15 characters), simply call the Generate method:

string id = ShortId.Generate();
// Example output: KXTR_VzGVUoOY

---

Customize ID Generation 🎨

ShortId provides several options to tailor the generated IDs to your needs:

Include Numbers

var options = new GenerationOptions(useNumbers: true);
string id = ShortId.Generate(options);
// Example output: O_bBY-YUkJg

Exclude Special Characters

var options = new GenerationOptions(useSpecialCharacters: false);
string id = ShortId.Generate(options);
// Example output: waBfk3z

Specify ID Length

var options = new GenerationOptions(length: 9);
string id = ShortId.Generate(options);
// Example output: M-snXzBkj

---

Customize ShortId 🎛️

ShortId allows you to fully customize the character set and even seed the random number generator for reproducible results.

Change the Character Set

You can define your own character set for ID generation:

string characters = "ⒶⒷⒸⒹⒺⒻⒼⒽⒾⒿⓀⓁⓂⓃⓄⓅⓆⓇⓈⓉⓊⓋⓌⓍⓎⓏⓐⓑⓒⓓⓔⓕⓖⓗⓘⓙⓚⓛⓜⓝⓞⓟⓠⓡⓢⓣⓤⓥⓦⓧⓨⓩ①②③④⑤⑥⑦⑧⑨⑩⑪⑫"; // Custom character set
ShortId.SetCharacters(characters);

Note:

• The character set must contain at least 50 unique characters.
• Duplicate and whitespace characters are automatically removed.

---

Set a Random Seed

For reproducible results, you can set a seed for the random number generator:

int seed = 1939048828;
ShortId.SetSeed(seed);

---

Reset Customizations

To reset all customizations (character set, seed, etc.) to their defaults, use the Reset method:

ShortId.Reset();

---
