Create a console application:

dotnet new console -o GremlinExample

Add Gremlin.Net:

dotnet add package Gremlin.Net -v 3.2.9

Create a GraphTraversalSource which is the basis for all Gremlin traversals:

var graph = new Graph();
var client = new GremlinClient(new GremlinServer("localhost", 8182));
// The client should be disposed on shut down to release resources
// and to close open connections with client.Dispose()
var g = graph.Traversal().WithRemote(new DriverRemoteConnection(client));
// Reuse 'g' across the application

Execute a simple traversal:

var herculesAge = g.V().Has("name", "hercules").Values<int>("age").Next();
Console.WriteLine($"Hercules is {herculesAge} years old.");

Next() is a terminal step that submits the traversal to the Gremlin Server and returns a single result. Other terminal steps can be found in TinkerPop’s reference documentation.

The traversal can also be executed asynchronously by using Promise() which is the recommended way as the underlying driver in Gremlin.Net also works asynchronously:

var herculesAge = await g.V().Has("name", "hercules").Values<int>("age").Promise(t => t.Next());
