MongoDB for C# developers

• Repository for the MongoDB C# docs gitbook
• Build MongoDB queries using the MongoDB C# driver
• Operators explanations with examples written in C# and node.js (shell)
• Advanced querying using LINQ

Gitbook 📘

The docs contain code samples for building MongoDB queries using the MongoDB C# driver an a typed way rather than using BsonDocument.

Example - $unwind operator 🚩

var travelersQueryableCollection = tripsDatabase
    .GetCollection<Traveler>(Constants.TravelersCollection)
    .AsQueryable();

var linqQuery = travelersQueryableCollection
    .SelectMany(t => t.Activities, (t, a) => new
    {
        age = t.Age,
        activity = a
    })
    .GroupBy(q => q.age)
    .Select(g => new { age = g.Key, activities = 
        g.Select(a => a.activity).Distinct() })
    .OrderBy(r => r.age);

var linqQueryResults = await linqQuery.ToListAsync();
