C# 具有多个值的Neo4jClient Cypher查询收集语句

我正在尝试将一个来自cypher的查询转换为在c中使用neo4jclient api#

这是我的密码

start server=node:node_auto_index(serverId='SHO2K3MS49')
MATCH 
 server-[:IS_SERVER_TYPE]->type,
 appEnv-[:HAS_SERVER]->server,
 app-[:HAS_ENV]->appEnv
return        
   server.serverId,
   collect([
   appEnv.environmentTypeId,
   appEnv.appEnvId,
   app.appId,
   app.appName
  ]) ;

该查询为每台服务器返回一行，并收集该服务器上的所有应用程序

就我所见，.CollectAs api只允许单个值

如何使用.NETAPI实现这一点

编辑

我刚刚试过这个问题

_connectedClient
 .Cypher                 
 .Start(new {server = Node.ByIndexLookup("node_auto_index", "serverId", "SHO2K3MS49") })
 .Match("server-[:IS_SERVER_TYPE]->type", "appEnv-[:HAS_SERVER]->server", "app-[:HAS_ENV]->appEnv")               
 .Return((server, appEnv, app) => 
  new
   {
       ServerName = Return.As<string>("server.serverId"),     
       aa = Return.As<dynamic>    ("collect([appEnv.environmentTypeId,appEnv.appEnvId,app.appId,app.appName])")                                                                                                                          
   })
 .Results;

消息——为简洁起见，删除了样板文本

Neo4jClient encountered an exception while deserializing the response from the server. This is likely a bug in Neo4jClient.

Include the full type definition of <>f__AnonymousType1`2[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Object, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]].

Include this raw JSON, with any sensitive values replaced with non-sensitive equivalents:

{"columns":["ServerName","aa"],"data":[["SHO2K3MS49",[["PRD","MATT.PRD","MATT","MATT"],["PRD","ARCSERV.PRD","ARCSERV","ArcServ"],["PRD","ACTIVE DIRECTORY _WINDOWS SERVER NETWORKING_.PRD","ACTIVE DIRECTORY _WINDOWS SERVER NETWORKING_","Active Directory (Windows Server networking)"]]]]}
Parameter name: content

Neo4jClient在反序列化服务器响应时遇到异常。这可能是Neo4jClient中的一个bug。
包括f_uuAnonymousType1`2的完整类型定义[[System.String，mscorlib，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089]，[System.Object，mscorlib，Version=4.0.0.0，Culture=neutral，PublicKeyToken=b77a5c561934e089]]。
包括此原始JSON，任何敏感值都替换为非敏感等效值：
{“列”：[“服务器名”、“aa”]、“数据”：[“SHO2K3MS49”[“PRD”、“MATT.PRD”、“MATT”、“MATT”]、[“PRD”、“ARCSERV.PRD”、“ARCSERV”、“ARCSERV”]、[“PRD”、“ACTIVE DIRECTORY\u WINDOWS SERVER NETWORKING\u.PRD”、“ACTIVE DIRECTORY\u WINDOWS SERVER NETWORKING\u”、“ACTIVE DIRECTORY（WINDOWS SERVER NETWORKING）”]]
参数名称：内容
这是因为从
collect
语句返回的结果基本上是没有定义列的字符串。JSON.NET无法推断列是什么（并且您不能使用
AS
来帮助它），因此您只能得到如下字符串：

"[\r\n"EnvType1",\r\n"AppEnvId1",\r\n"App2",\r\n"App 2"\r\n]"

您可以使用以下查询获得：

_connectedClient
    .Cypher                 
    .Start(new {server = Node.ByIndexLookup("node_auto_index", "serverId", "SHO2K3MS49") })
    .Match("server-[:IS_SERVER_TYPE]->type", "appEnv-[:HAS_SERVER]->server", "app-[:HAS_ENV]->appEnv")               
     .Return((server, appEnv, app) => 
      new
       {
           ServerName = Return.As<string>("server.serverId"),     
           aa = Return.As<IEnumerable<string>>("collect([appEnv.environmentTypeId,appEnv.appEnvId,app.appId,app.appName])")                                                                                                                          
       })
     .Results;

我认为这会以您想要的方式为您提供结果，我想这里的问题是，在服务器上执行
收集
，还是在客户端执行
GroupBy

"[\r\n"EnvType1",\r\n"AppEnvId1",\r\n"App2",\r\n"App 2"\r\n]"

    .Cypher

    .Match("server-[:IS_SERVER_TYPE]->type", "appEnv-[:HAS_SERVER]->server", "app-[:HAS_ENV]->appEnv")               
     .Return((server, appEnv, app) => 
      new
       {
           ServerName = Return.As<string>("server.serverId"),     
           aa = Return.As<IEnumerable<string>>("collect([appEnv.environmentTypeId,appEnv.appEnvId,app.appId,app.appName])")                                                                                                                          
       })
     .Results;

    .Match("server-[:IS_SERVER_TYPE]->type", "appEnv-[:HAS_SERVER]->server", "app-[:HAS_ENV]->appEnv")
    .Return((server, appEnv, app) =>
        new
