Neo4JClient:如何查看关系(直接报告者)? [英] Neo4JClient: How to view the relationship (Direct reportees)?

问题描述

我有一个使用 Neo4JClient:如何创建关系的关系创建示例? .如何看待这种关系?我的意思是，如果我想查找直接连接到"A"的节点数，该怎么做?

I have an example of creating relationship using Neo4JClient: How to create relationships?. How to view the relationship? I mean if I want to find how many nodes are directly connected to "A", how to do that?

在@manonthemat的帮助下，我将密码转换为C#

After a little help from @manonthemat, I converted the cypher in C#

var record = client.Cypher
                    .Match("(A)-[r]->()")                   
                    .Return((A, r) => new
                    {
                        User = A.As<ExampleNode>(),
                        NumberOfFriends = r.Count()
                    }).Results;

尽管我能够获得A的直接计数为4，但我也想获得这些名称，例如B，C，D，E.怎么做?

Though I am able to get the direct count say 4 for A, I also want to get the names of those e.g. B,C,D,E. How to do so?

推荐答案

我理解您的问题是如何确定连接到A的节点?"

I understand you question to be "How do I determine the nodes which are connected to A?"

如果只需要节点，则密码查询应如下所示:

If you only want the nodes, the cypher query should look something like this:

Match A-[r:*]-(X)
Return distinct X

如果您还想要这种关系，请尝试以下操作:

If you also want the relationships try this:

Match A-[r:*]-(X)
Return r, distinct X

有时候，您可能希望将搜索范围限制为仅某种类型的关系，例如"KNOWS".在这种情况下，请尝试以下操作:

Sometimes you may want to limit you search to only a certain kind of relationship, like "KNOWS". In which case try this:

Match A-[r:KNOWS*]-(X)
Return r, distinct X
