odata

问题 I have set up a multi targetting (net4.5.2/netstandard2) class library allowing to consume one of our enterprise OData services. To access this OData service we use a proxy class generated with the OData v4 Client Code Generator (v7.5.0) Unfortunately, when trying to use my library in a Netcoreapp2.1 application I encounter an issue as soon as I try to enumerate a collection. Container.MyDataSet.ToList(); produces the following exception : "System.NotSupportedException : This target framework

问题 I am using the following C# OData packages, in a .NET Web Api project: Install-Package Microsoft.AspNet.OData Install-Package Microsoft.AspNet.WebApi.OData When following Microsoft's example Use Open Types in OData v4, everything seems to work as expected, as long as the open type does not contain additional nested open complex types. This means that this will work fine: public class WplController : ODataController { private List<AbstractMongoDocument> _documents = new List

问题 I'm using OData v4 with WebAPI with these nuget-packages: Microsoft.Data.OData 5.7.0 Microsoft.AspNet.WebApi.OData 4.0.30506 I can't get groupby to work with count. It should be the most simple thing. I have a simple table/entity called Delivery . It has a status column (among several other ones). What I basically want to do is this SQL query, but with OData: SELECT e.status, count(*) AS total FROM Delivery e GROUP BY e.status I've tried using countdistinct, but it doesn't give me the correct

问题 Im working on a .Net Web Api 2.2 project and I'm using Odata v4 and Entity Framework code first. I need to have a calculated property in a Model which is not to be saved in Database. I have tried [notmapped] attribute. But it hides the property in Odata $medadata. How can I overcome this issue? 回答1: You can manually add this property into model. You can refer to the sample codes in: How to get Web API OData v4 to use DateTime Hope it can help. 来源： https://stackoverflow.com/questions/31191013

问题 I have an asp.net core 3.2 api which uses ef core and OData to return data to the client. I need to be able return the count of an expanded one-to-one property in a list of objects along with the parent object list. Since I am paging the results, the @odata.count represents the count of records in the database that match the criteria, not the count of records it actually returns. To explain lets say we have a couple of classes public class Order { public int Id { get; set; } public string

问题 Microsoft.AspNet.Odata changed the way you register services like serializers. What should the new format look like? 回答1: Your new config should look something like this. You need to add at least the first 2 services (IEdmModel and IEnumerable IODataRoutingConvention), and then you can add your own. For example, a custom odata serializer provider. using Boomerang.OData; using Boomerang.Models; using Microsoft.OData; using Microsoft.OData.Edm; using System; using System.Collections.Generic;
