Get attribute of relationship nodes in Neo4j using Neo4jClient

I use Neo4jClient and I want to get relation attribute MATCH (n:Users {id:1})-[r]-(m:Users) RETURN r how I can get node with attribute relation , for example :

Node[0]{id:1,name:"Oliver Stone"}
Node[1]{id:2,name:"Charlie Sheen"}
Node[2]{id:3,name:"Martin Sheen"}
Node[3]{id:4,name:"TheAmericanPresident"}

I should know , what is attribute relation between Node[0] and Node[2]? (attribute mean "FOLLOW" or "IGNORE")

You can get the TypeKey from the r value you are also retrieving:

var query = Client.Cypher
    .Match("(n:User)-[r]-(m:User)")
    .Where((UserEntity n) => n.Id == 1)
    .Return((n, r, m) => new
    {
        N = n.As<UserEntity>(),
        M = m.As<UserEntity>(),
        R = r.As<RelationshipInstance<object>>()
    });

var res = query.Results;
foreach (var item in res.ToList())
    Console.WriteLine("({0})-[:{1}]-({2})", item.N.Id, item.R.TypeKey, item.M.Id);

You'll obviously need to change UserEntity for whatever your type actually is.
