Short Unique IDs in .NET (C#)

What is Sqids?

Sqids (pronounced "squids") is an open-source library that lets you generate short unique identifiers from numbers. These IDs are URL-safe, can encode several numbers, and do not contain common profanity words. Read more .

This is what they look like:

.NET (C#)

Quick encode & decode example:

var sqids = new SqidsEncoder<int>();
var id = sqids.Encode(1, 2, 3); // "86Rf07"
var numbers = sqids.Decode(id); // [1, 2, 3]

If IDs are too short, you can pad them to a certain length:

var sqids = new SqidsEncoder<int>(new()
{
  MinLength = 10,
});
var id = sqids.Encode(1, 2, 3); // "86Rf07xd4z"
var numbers = sqids.Decode(id); // [1, 2, 3]

Create unique IDs by shuffling the alphabet:

var sqids = new SqidsEncoder<int>(new()
{
  Alphabet = "k3G7QAe51FCsPW92uEOyq4Bg6Sp8YzVTmnU0liwDdHXLajZrfxNhobJIRcMvKt",
});
var id = sqids.Encode(1, 2, 3); // "XRKUdQ"
var numbers = sqids.Decode(id); // [1, 2, 3]
