问题 I have a Windows Phone 7 application that is utilizing the DataServicesClient to access a WCF DataService (ODATA) and I want to ask the service to compress the response. I know if the Request Headers includes "Accept-Encoding" header with the value of "gzip" the WCF DS will compress the response. Is there a way to add this header to the Request when using the DataServicesClient on WP7? The Request Headers collection appears to be readonly. What I would like to be able to do is the following

问题 I tried to use $count in an $expand like this query .../OData/Foo(1)?$expand=Bars($count=true) However count is no where to be found in the result. { "...": "...", "Bars": { "...": "..." } } No error either. I'm using ASP.NET Web API OData 5.4, which is using OData v4. What gives? Not implemented yet? 回答1: This feature hasn't been implemented yet.

问题 I have built a few WebAPIs since it was born, including one supporting OData URL filters when that was new. I see now that OData over WebAPI has matured, I see it can serve service metadata. Is it complete enough for Excel or other OData client tooling to plug and play as if it were a full WCF Data Service (ye olde Astoria)? That's it. Thanks 回答1: It is. In the past you had to do the right configuration or do a workaround to populate the OData feed from Web API correctly, to be able to

问题 I'm consuming a Odata WebApi.2.1 Service in a Odata v4 client. When I attempt to update the entity, and I'm getting following error: "UpdateRelatedObject method only works when the sourceProperty is not collection" I have below code in my application. public class Customer { int CustomerId; string CustomerName; ICollection<Order> Orders; } public void Save() { foreach (var item in Customer.Orders) { Context.UpdateRelatedObject(Customer, "Orders", item); } Context.UpdateObject(Customer);

问题 I have a data source provider : public class DSProvider { public IQueryable<Product> Products { get { return _repo.Products.AsQueryable(); } } } The repository in the above example currently gets ALL the records (of Products) from DB and then applies the filters, this just does not sound right if you had 50000 requests/sec from a website.How can you limit the repository to just return required info from DB without converting the service to a tightly coupled request option i.e. opposite of

问题 I am working with Simple Odata Library https://github.com/object/Simple.OData.Client/wiki I need to define open parameters, but i dont seam to see any definition or documentation for this. Example for clarification: Along with my oData call, i send a parameter called "mode", which i can set to any number between 0-10. My server will know what to do with it. This parameter however is not pre-defined. 回答1: Recent releases of Simple.OData.Client support OData open types, look at examples here:

问题 I can generate an IEdmModel from a $metadata document with something like this: HttpWebRequest request = HttpWebRequest.CreateHttp("http://services.odata.org/v3/odata/OData.svc/$metadata"); ClientHttpResponseMessage metadataMessage = new ClientHttpResponseMessage((HttpWebResponse)request.GetResponse()); using (var messageReader = new ODataMessageReader(metadataMessage)) { IEdmModel model = messageReader.ReadMetadataDocument(); } Is there a way to do the reverse? Given a IEdmModel generate the
