I have created an OData service and now I am trying to consume this service at client side. I wants to create an expression such as for the below url in the c# query expression-
http://odata.org/Product-Service/Product(150)
The above url is working fine in browsers but I want to create query expression in the C# for the above url. Any help would be greatly appreciable.
You could use a DataServiceContext
+ DataServiceQuery
in System.Data.Services.Client
to hit the Url. Remember no query is executed until the call to First() due to lazy loading.
var context = new DataServiceContext(new Uri("http://odata.org/Product-Service"), DataServiceProtocolVersion.V3);
var query = context.CreateQuery<Product>("Product");
Product product = query.Where(p => p.Id == 150).First();
The above should resolve to http://odata.org/Product-Service/Product(150) which you can check by looking at the query.Entities
collection. Each entity in the collection will contain a Uri.
Also if your Product class contains a navigation property, you will need to add the expand query option thus:
var query = context.CreateQuery<Product>("Product").
AddQueryOption("$expand", "NavigationProperty");
