LINQ Integration

Curiosity's query system is designed to integrate seamlessly with modern C# features, including LINQ (Language Integrated Query).

The Query interface provides a fluent builder for executing operations on the graph engine. However, once you retrieve results, you often need to perform further processing in memory.

AsEnumerable() and Standard LINQ

The AsEnumerable() method terminates the graph query and returns an IEnumerable<ReadOnlyNode>. From this point on, you can use standard LINQ methods.

var nodes = Graph.Query()
    .StartAt("Person")
    .AsEnumerable();

// Use standard LINQ
var sortedNames = nodes
    .Where(n => n.GetInt("age") > 30) // In-memory filtering
    .Select(n => ( Name: n.GetString("name"), Age: n.GetInt("age") )) // Projection to Tuple
    .OrderBy(x => x.Name) // In-memory sorting
    .ToList();
