ODataProperties (System.Web.OData.Extensions - OData v4) 缺少“模型”属性

Question

I am trying to create an instance of ODataQueryContext which requires an EdmModel reference. I am attempting to get the Model from ODataProperties() which is a method call off of the HttpRequestMessage object.

var orderBy = new OrderByQueryOption("ColumnName desc", new ODataQueryContext(Request.ODataProperties().Model, typeof(MyType)));

It seems that if I use the namespace using System.Web.Http.OData.Extensions; as opposed to using System.Web.OData.Extensions; the Model property is available from ODataProperties() . However, I am using the newer version (OData v4) namespaces, for other references in my program.

After doing some research I determined that with OData v4, they moved everything from Web.Http.OData.* namespaces, to Web.OData.* namespaces. I am assuming that I need to be consistent in using either the new or old namespaces, and I was not successful attempting to mix them.

Does anyone know how to get the Model property from ODataProperties() without using the older Web.Http.OData namespaces?

Answer 1

To anyone still having trouble with this (I ended-up here from a MS OData tutorial) request.ODataProperties().Model has changed to request.GetModel() ( HttpRequestMessageExtensions in namespace Microsoft.AspNet.OData.Extensions in assembly Microsoft.AspNet.OData). Also request.ODataProperties().PathHandler has changed to request.GetPathHandler() .

在 ASP.NET Core 3.1 包 Microsoft.AspNetCore.OData 中， Request.ODataProperties()下的大多数值现在位于Request.ODataFeature() 。

ODataProperties().Model 来自 github 上的 OData
