使用OData在我的数据库中插入新记录

I've a OData services running on my application, and I've created a odata client, to update, save and deleted information using that OData services. The thing is I can access the data using the odata services but I don't know how to insert a new record or update a record. This is how i've been trying:

我在我的应用程序上运行了OData服务,并且我创建了一个odata客户端,使用该OData服务更新,保存和删除信息。问题是我可以使用odata服务访问数据,但我不知道如何插入新记录或更新记录。这就是我一直在尝试的方式:

When my Odata Client starts:

当我的Odata客户端启动时:

void MainWindow_Loaded(object sender, RoutedEventArgs e) 
{
            FutbolContext ctx = new FutbolContext(new Uri("http://localhost:56156/FutbolService.svc"));
            DataServiceCollection<Team> TeamDS = new DataServiceCollection<Team>();

            var qry = from w in ctx.Teams
                      select w;

            TeamDS.Load(qry);

            Team myTeam = new Equipo();

            myTeam.Name = "Caracas F.C";
            myTeam.City = "Caracas";

            TeamDS.Add(myTeam);
            ctx.SaveChanges();
}

I haven't been able to find tutorials about inserting and updating records through OData using C#. I hope some one can help me. Thanx in advance.

Your code above loads the entities into a collection TeamDS but then it adds a new entity into a collection equipoDS. Since there's no equipoDS defined in your sample above I assume it's a completely different collection in which case it's not supposed to work. If you would add the entity into the TeamDS it will actually work (I tried a similar code myself).

上面的代码将实体加载到集合TeamDS中,然后将新实体添加到集合中。由于上面的示例中没有定义equipoDS,我认为它是一个完全不同的集合,在这种情况下它不应该工作。如果你将实体添加到TeamDS中它实际上会工作(我自己尝试过类似的代码)。
