ASP.NET Odata Web API CRUD操作不起作用

Question

I have spent a about 2 days setting up my Odata Web API project that was before a simple Asp.net mvc4 project.

But still I am not successful in operating even CRUD Operations. It says this:

<m:message xml:lang="en-US">
No HTTP resource was found that matches the request URI 'http://localhost:53208/odata/Product'.
</m:message>
<m:innererror>
<m:message>
No action was found on the controller 'Product' that matches the request.
</m:message>
<m:type/>
<m:stacktrace/>
</m:innererror>

It means its reaching the Controller but not finding actions or there is some problem in my routing settings.

I have following in my WebApiConfig:

config.Routes.MapODataRoute("OData","odata",GetEdmModel());

My getEdmModel method:

private static IEdmModel GetEdmModel()
    {
        ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
        builder.EntitySet<Product>("Product");
        builder.EntitySet<OfferedProduct>("OfferedProduct");


        IEdmModel model = builder.GetEdmModel();

        return model;
    }

My controller is like this:

public class ProductController : EntitySetController<Product,int>
{
    private OfferAssistantDbContext db = new OfferAssistantDbContext();
    List<Product> Products = new OfferAssistantDbContext().Products.ToList();
    // GET api/Product
    [Queryable(PageSize = 10)]
    public override IQueryable<Product> Get()
    {
        return Products.AsQueryable();
    }

    // GET api/Product/5
    public Product GetProduct([FromODataUri] int id)
    {
        return Products[id];
    }
    /// and so on... but for this time lets work only on GET operation 

Now when I write this in my browser:

http://localhost:53208/odata/Product

it says the error I showed above..

我相信您的控制器需要从ODataController继承：

public class ProductController : ODataController
