排序查询Azure移动服务

Question

I have a Azure mobile service and I would like to sort the result before handing them to the receiving end.

This is the GetTables function :

 // GET tables/BPNews
    public IQueryable<BPNews> GetAllBPNews()
    {
        return Query().OrderByDescending(x => x.DateStart).Where(x => x.DateStart <= DateTime.Now && x.DateEnd >= DateTime.Now);
    }

I would like to have the results sorted by 'DateStart', but whatever property I sort by it's not been sorted at all.

Here is the BPNews class :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Microsoft.WindowsAzure.Mobile.Service;

namespace BeautyPointGroningenService.DataObjects
{
public class BPNews : EntityData
{
    public string Subject { get; set; }
    public DateTime Date { get; set; }
    public string Message { get; set; }
    public DateTime DateStart { get; set; }
    public DateTime DateEnd { get; set; }
}
}

Hope you guys can help me out.

Thanks in advance and happy holidays!

Answer 1

If you change your code to:

    // GET tables/BPNews
    public IQueryable<BPNews> GetAllBPNews()
    {
        return Query().Where(x => x.DateStart <= DateTime.Now && x.DateEnd >= DateTime.Now);
    }

...you can specify the sort order on the client by using OData query operations: http://msdn.microsoft.com/en-us/library/azure/jj677199.aspx

So your query could look like:

    tables/BPNews?$orderby=DateStart

By using the Mobile Services SDK it is much more convenient: http://azure.microsoft.com/en-us/documentation/articles/mobile-services-windows-dotnet-how-to-use-client-library/#sorting
