SequentialGuid.MongoDB

NuGet NuGet Downloads

MongoDB integration for the SequentialGuid library. Provides a drop-in IIdGenerator for automatic sequential Guid document IDs and BSON serializers for the SequentialGuid / SequentialSqlGuid struct types.

Install

dotnet add package SequentialGuid.MongoDB

Requires MongoDB.Bson 2.29.0 or later.

Features

Feature Description
MongoSequentialGuidGenerator IIdGenerator implementation - generates sequential Guid IDs for documents automatically
BSON serializers Transparent serialization of SequentialGuid and SequentialSqlGuid (including nullable variants)

Quick Start

1. Register the ID generator

Register the singleton generator so MongoDB uses sequential GUIDs for all Guid id properties:

using SequentialGuid.MongoDB;

// Register as the default Guid id generator
MongoSequentialGuidGenerator.Instance.RegisterMongoIdGenerator();

2. Register the BSON serializers

If your documents use SequentialGuid or SequentialSqlGuid as property types (not just raw Guid), register the serialization provider:

using MongoDB.Bson.Serialization;
using SequentialGuid.MongoDB.Serializers;

BsonSerializer.RegisterSequentialGuidSerializers();

This registers serializers for SequentialGuid, SequentialGuid?, SequentialSqlGuid, and SequentialSqlGuid?.

3. Use in your document models

Option A - Raw Guid with automatic generation:

public class Order
{
    public Guid Id { get; set; }

    public string Description { get; set; } = string.Empty;
}

// Insert - Id is generated automatically by MongoSequentialGuidGenerator
await collection.InsertOneAsync(new Order { Description = "Widget" });

Option B - Strongly-typed struct properties:

using SequentialGuid;

public class Order
{
    public SequentialGuid Id { get; set; } = new();

    // Timestamp is always available from the ID itself
    public DateTime? CreatedAt => Id.Timestamp;

    public string Description { get; set; } = string.Empty;
}

Complete setup example

using MongoDB.Bson.Serialization;
using MongoDB.Driver;
using SequentialGuid.MongoDB;
using SequentialGuid.MongoDB.Serializers;

// One-time setup (typically in Program.cs or a startup class)
MongoSequentialGuidGenerator.Instance.RegisterMongoIdGenerator();
BsonSerializer.RegisterSequentialGuidSerializers();

// Use MongoDB as normal
var client = new MongoClient("mongodb://localhost:27017");
var db = client.GetDatabase("myapp");
var orders = db.GetCollection<Order>("orders");

await orders.InsertOneAsync(new Order { Description = "Widget" });

How It Works

  • MongoSequentialGuidGenerator implements IIdGenerator and calls GuidV8Time.NewGuid() to generate each ID. It considers any Guid value that is not Guid.Empty as non-empty.
  • SequentialGuidSerializer<T> delegates to the default Guid BSON serializer for the wire format, then wraps/unwraps the struct type on read/write. This means documents stored with raw Guid IDs remain compatible.
