Make a linked list using cypher neo4j - neo4j

Question

Is there any possible way to make a linked list in cypher within one transaction ?
Iv'e tried ForEach with Match but according to neo4jClien it is not possible to set Match in ForEach.
My approach :
public static void save(List<Post> nodes)
{
var gclient = graphdb.getConnection();
var create1 = gclient.Cypher.Create("(p:Post {nodes})");
var match = gclient.Cypher.Match("((t)-[r:lastPost]->(last))");
var create3 = gclient.Cypher.Create("t-[:lastPost]->p, p-[:next]->last");
var delete = gclient.Cypher.Delete("r");
string query = create1.Query.QueryText + " " + match.Query.QueryText + " "
+ create3.Query.QueryText + " " + delete.Query.QueryText;
gclient.Cypher
.Match("(t:Tmp)")
.WithParam("nodes", nodes)
.ForEach("(newPost in {nodes} | " + query + ")")
.ExecuteWithoutResults();
}
Thanks in advance .

Answer 1

this should do the trick.
static Neo4jClient.Cypher.ICypherFluentQuery addnode<T>(Neo4jClient.Cypher.ICypherFluentQuery q, IList<T> items, int idx, string label)
{
string sq = string.Format("({0}:{1} {{{2}}})", "c" + idx, label, "a" + idx);
q = q.Create(sq).WithParam("a" + idx, items[idx]);
return q;
}
static Neo4jClient.Cypher.ICypherFluentQuery addlink<T>(Neo4jClient.Cypher.ICypherFluentQuery q, int idx1, int idx2)
{
string sq = string.Format("{0}-[:LINKEDTO]->{1}", "c" + idx1, "c" + idx2);
q = q.Create(sq);
return q;
}
public static void Sample<T>(List<T> items, GraphClient client)
{
Neo4jClient.Cypher.ICypherFluentQuery q = client.Connection.Cypher;
for (int i = 1; i < items.Count; i++)
{
q = addnode<T>(q, items, i-1, "MYITEM");
if(i>1)
q = addlink<T>(q, i-2, i-1);
}
q.ExecuteWithoutResults();
}
