问题 I believe I am missing something obvious here. When I request a JSON response from an OData service I get a different result for the DateTime properties than I do when I request XML. I'll use the NerdDinner OData feed as an example. JSON: http://www.nerddinner.com/Services/OData.svc/Dinners(1)?$format=json "EventDate": "\/Date(1235764800000)\/" XML: http://www.nerddinner.com/Services/OData.svc/Dinners(1) <d:EventDate m:type="Edm.DateTime">2009-02-27T20:00:00</d:EventDate> When I do an alert

问题 I am creating a WCF data service on top of a EF 4.1 code first data model that goes against a multi-tenant database. In order to enforce the rules of accessing the multi-tenancy I want to require a string id (that is required by all of our MVC-based REST services) be passed as part of the url route. So, for example, right now I have a service route like this: http://mysample.net/mysamplesvc.svc/Users That returns all users in the db w/o a filter. I want to partition this by client by

问题 I am playing around with the Netflix odata service to get a better understanding of how to consume odata data. In VS 2010 I added a service reference to the NetFlix odata service. I then wrote this code which returns only some of the data. var cat = new NetflixCatalog(new Uri("http://odata.netflix.com/v1/Catalog/")); var x = from t in cat.Titles where t.ReleaseYear == 2009 select t; foreach (Title title in x) { ProcessTitle(title); } I looked at the uri generated for the call and ran it in a

问题 In the OData:Operations documentation, section 2.4 fourth paragraph down, it reads when creating an entity with POST it is also possible to create a link within the same request. However, I'm having trouble trying to make this work. A similar question has been asked about many-to-many linking while creating and it looks like that particular scenario isn't possible without a batch request. Below is the scenario I'm trying to create using this sample OData read write service. Create a new

问题 Continuing on after my initial WebApi Filtering and paging a projection Dilemma Breeze $filter projections thread I am now trying to update my backend database with little success. Giving the Fact that I am: public IQueryable<ConsigneDTO> Consignees(string refname) { IQueryable<ConsigneDTO> q = this.db.Consignes .Where(x => x.Refname == refname) .Select(f => new ConsigneDTO {Refname = f.Refname, Consignee = f.Consignee, Address1 = f.Address1, Address2 = f.Address2, Address3 = f.Address3});

问题 I have a data service that takes a byte array. I then have a web page that attempts to send a file to that data service. If the file is small (say 50kb) then everything functions as expected, however if the file is large (anything over 100kb) I get a "BadRequest" error message on the save change call for the data service. Is there a way to enable larger data sizes to be passed to the data service? EDIT (more details): I've set maxRequestLength higher and tried some webHttpBinding to increase

问题 I have searched far and wide and been completely unable to find any good samples or tutorials of how to call service operations using the ODataLib. I've seen several that tell me how to get entities and entity sets and that's great, but in order to call a service operation. I'm almost positive that I need to use something other than an ODataEntry , ODataFeed or ODataNavigationLink object. I've opened up the library in JustDecompile and see classes like ODataAction and ODataFunction but can't

问题 Client code: Public Sub sendEmpValue(name As String, value As List(Of Integer)) Dim serviceObject As New Service.GetEmployeeClient serviceObject.DoWork(name, value)** getting error at the value** End Sub Service code: Sub DoWork(name As String, value As List(Of Integer)) Implements IGetEmployee.DoWork End Sub 回答1: The DoWork method expects an Integer() which is an array of integers . The List(Of T) class has got a function called ToArray() which will return the list as an array. Call that and
