C＃：执行neo4j Cypher查询，该查询的Where子句中包含路径

Question

我正在尝试从c＃codeBehind获取给定节点的FOAF节点。 密码是

MATCH (current { PRSN_F_Name: 'MyName' })-[:KNOWS*1..2]->(fof) 
WHERE NOT (current)- [:KNOWS]->(fof) 
RETURN fof.PRSN_F_Name

如何使用C＃实现此查询？

好

我自己找到了答案...它必须像下面这样：

var q = client.Cypher
            .Match("(current { PRSN_F_Name: '" + txtName.Text + "' })-[:KNOWS*1..2]->(fof)")
            .Where("NOT (current)-[:KNOWS]->(fof)")
            .Return((fof) => fof.As<Person>());

        foreach (var result in q.Results)
        {
            ltrFeedback.Text = ltrFeedback.Text + result.PRSN_F_Name + "<br>";
        }
