neo4j - neo4jclient: create and related multiple node to another node -

it's hard ask question, not sure if have picked right title it. please bare me.

imagine classes in c#:

    public class user     {         public int id { get; set; }         public string username { get; set; }     }  public class post {     public int id { get; set; }     public string text { get; set; }     public string[] hashtags { get; set; } } 

each user can add post , relation between them author, each post have array of hash-tags each of them going separate node in graph.

when going save each post, find user in grph, create post node , relate them author relationship.

the question how can create , relate each hashtag post in same query. (to inside transaction).

how dynamically add item query create it. problem not create node , relation in 1 line of create.

here have tried far:

var cypherquery = db.instance.cypher                 .match("(user:user)")                 .where((user user) => user.username == "xyz")                  .create("user-[:author]->(post:post {newpost})")                 .withparam("newpost", new post() {id = 1, text = "here post #somehashtag"});                  //how relate node number of hashtags in post object???                 cypherquery.executewithoutresults(); 

is in single query or should divide in multiple round trips.

i have tried foeach seams post not have value inside foreach loop:

i have tried this:

var cyphercommand = db.instance.cypher                 .match("(user:user)")                 .where((user user) => user.username == "farvashani")                  .create("user-[:author]->(post:post {newpost})")                 .withparam("newpost", "here post @tag1 , tag2")                 .foreach(@"(hashtag in {hashtags}|                             merge post-[:mentioned]->(hash:hashtag {text: hashtag}))")                 .withparam("hashtags", new string[] {"tag1", "tag2"});                 cyphercommand.executewithoutresults(); 

any appreciated.

in opinion, think have pre-process text property first.

 string text = ""here post #somehashtag""; // example  list<string> hashtags = new list<string>();  int cnt = 0;  foreach (match match in regex.matches(text, @"(?<!\w)#\w+"))     {         hashtags.add(match.value);     } 

then create new instance of post:

post newpost = new post         {             id = 1,             text = "here post #somehashtag",             hashtags = hashtags         }; 

so, can use cypher:

var cyphercommand = db.instance.cypher             .match("(user:user)")             .where((user user) => user.username == "farvashani")              .create("user-[:author]->(post:post {newpost})")             .withparam(new {newpost}).executewithoutresults(); 

hope help.

p/s: ask question? think better retrieve separated graph if use each hashtag label of post? newpost:somehashtag example?
