Question

我正在尝试使用.NET IPP DevKit v3查询发票。

根据文档网站上的所有说明，我可以在使用ONLY默认字段时查询发票并通过/ where / etc添加skip / take / order到查询。但是，只要我添加非默认字段，跳过/ 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

我在这里缺少什么？

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();

我尝试了API资源管理器 -

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?

现在可以使用最新版本（IppDotNetSdkForQuickBooksApiV3.2.0.0）

以下是一个例子：

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...
}

使用非默认字段时，IPP v3 Invoice QueryService无法使用Skip / Take
