Flex vs. NET Interop (eight): Remote access using FLUORINEFX gateways

About remote access in this series of articles have written a lot of examples, this article is not prepared to delve into, in order to consolidate the FluorineFX gateway learning and use. In this paper, we will use the FluorineFX gateway to provide a number of functions such as data services to introduce the relevant knowledge of remote access through FLUORINEFX.

FLUORINEFX provides remote access including a number of aspects of the knowledge point, this article only describes three of them: access to the remote object return object, return to the DataTable, return the DataSet object. FluorineFX installation package with the associated sample program, To learn more you can refer directly to these sample programs.

Before implementing the visit, we also do some preparatory work to establish the remote objects, as follows:

1 namespace Fluorine.ServiceLibrary
2 {
3 public class Book
4 {
5 public int Id { get; set; }
6 public string Name { get; set; }
7 public string Author { get; set; }
8 public double Price { get; set; }
9 }
10 }

The following are the remote objects that provide flex access:

1 namespace Fluorine.servicelibrary
2 {
3 [Remotingservice]
4 public class Fluorineservice
5 {
6///<summary>
7///Returns a Simple object

Ten public book GetBook ()
11 {
Return to new book
13 {
Id = 1,
Name = "The Kingdoms of the",
Author = "Luo Guan Zhong",
Price = 100
18};
19}

27 {

DT. Columns.Add ("Id", typeof (int));

DT. Columns.Add ("Author", typeof (String));
DT. Columns.Add ("Price", typeof (Double));
