我如何从后面的代码使用RIA/LINQ [英] How do i work with RIA/LINQ from code behind

问题描述

我有一个问题，我看了几个有关如何使用RIA服务填充数据网格的教程，但我不希望这样.相反，我想到达对象，然后从那里设置一些变量.

像这样的东西:

I have a problem, i have watch several tutorials on how you populate a datagrid with RIA services but i dont want that. Instead i want to reach the object and from there i want to set some variables.

Something like this:

---- CODE BEHIND------
List<dbBook> books = new List<dbBook>
dbBook book = contex.GetDbBookByIDQuery(870);
int id = book.ID;
books.Add(book);

----- DomainService -------
public dbBook GetDbBookByIDQuery(int bookID)
{
   dbBook book;
   book = this.ObjectContext.dbBook(b => b.ID == bookID);
   return book;
}

我敢打赌，这确实很容易，但是我被困住了，这开始变得非常令人沮丧:mad:

感谢所有帮助！

I bet this is really easy but i am stuck and this starts to get really frustrating:mad:

I appreciated all help!!
