我正在尝试使用 .NET IPP DevKit v3 查询发票。

按照文档站点上的所有说明，我可以在仅使用默认字段时查询发票并在查询中添加skip/take/order by/where/etc。但是，一旦我添加了非默认字段，skip/take/order by/where/etc 似乎不起作用。

这是错误：

System.ArgumentException was unhandled
  HResult=-2147024809
  Message=Expression of type 'System.Collections.Generic.IEnumerable`1[<>f__AnonymousType0`3[Intuit.Ipp.Data.Invoice,Intuit.Ipp.Data.Line[],Intuit.Ipp.Data.LinkedTxn[]]]' cannot be used for parameter of type 'System.Linq.IQueryable`1[<>f__AnonymousType0`3[Intuit.Ipp.Data.Invoice,Intuit.Ipp.Data.Line[],Intuit.Ipp.Data.LinkedTxn[]]]' of method 'System.Linq.IQueryable`1[<>f__AnonymousType0`3[Intuit.Ipp.Data.Invoice,Intuit.Ipp.Data.Line[],Intuit.Ipp.Data.LinkedTxn[]]] Skip[<>f__AnonymousType0`3](System.Linq.IQueryable`1[<>f__AnonymousType0`3[Intuit.Ipp.Data.Invoice,Intuit.Ipp.Data.Line[],Intuit.Ipp.Data.LinkedTxn[]]], Int32)'
  Source=System.Core

我在这里想念什么？

代码：

string AppToken = "your AppToken goes here";
string AppConsumerKey = "your AppConsumerKey goes here";
string AppConsumerKeySecret = "your AppConsumerKeySecret goes here";
string AccessToken = "your AccessToken goes here";
string AccessTokenSecret = "your AccessTokenSecret goes here";
string RealmCompanyId = "your RealmId goes here";

OAuthRequestValidator oauthValidator = new OAuthRequestValidator(AccessToken, AccessTokenSecret, AppConsumerKey, AppConsumerKeySecret);
ServiceContext context = new ServiceContext(AppToken, RealmCompanyId, IntuitServicesType.QBD, oauthValidator);
QueryService<Intuit.Ipp.Data.Invoice> qs = new QueryService<Intuit.Ipp.Data.Invoice>(context);

// This works...
var defaultQuery = qs.Select(c => c).Skip(0).Take(10).OrderBy(c => c.Id);
var defaultList = defaultQuery.ToList();

// This works...
var nonDefaultQuery = qs.Select(c => new { c, c.Line, c.LinkedTxn });
var nonDefaultList = nonDefaultQuery.ToList();

// This does NOT work!!
var nonDefaultQueryWithSkip = qs.Select(c => new { c, c.Line, c.LinkedTxn }).Skip(0).Take(10);
var nonDefaultListWithSkip = nonDefaultQueryWithSkip.ToList();

我在 API 资源管理器上试过 - 

Select *,Line.*, LinkedTxn.* FROM Invoice startPosition 1  maxResults 10 (which is your last query) and it works fine but not from .net sdk. I will double check this on the .net SDK and get back to you. Can you verify that you get the correct results on API explorer from this query?

这现在适用于最新版本（IppDotNetSdkForQuickBooksApiV3.2.0.0）

这是一个例子：

QueryService<Intuit.Ipp.Data.Invoice> qs = new QueryService<Intuit.Ipp.Data.Invoice>(context);

string query = string.Format("SELECT *, Line.* FROM Invoice ORDERBY Id STARTPOSITION {0} MAXRESULTS {1}", startPos, pageSize);

var recs = qs.ExecuteIdsQuery(query);

foreach (Intuit.Ipp.Data.Invoice rec in recs)
{
    // do stuff...
}

.
