Flex与FluorineFx传值
最近学习了一下Flex + FluorineFx，其中遇到了一个问题，就是FluorineFx与Flex之间怎样传值，为了这个问题在网上找了不少资料，然后有自己试了一下，下面把我的成果分享一下。
（1）传类对象，我这里没成功，不知为啥，但是网上有很多成功示例。
（2）传DataSet ，网上说加上这句话 [DataTableType( "ServiceLibrary.Book")]就行，但是我试过之后
不可以，也有说加上[DataSetType("ServiceLibrary.Book")]的，但是我试过之后在.Net端就没数据了，更别提
Flex端了。
（3）传DataTable，成功了，关键是加上 [DataTableType( "ServiceLibrary.Book")]。
（4）传XmlDocument，成功了。
（5）传String，成功了，其实String保存的也是XML形式，跟XmlDocument差不多。
（6）传 List<>，成功了，网上也有很多人都用这种方式。
FluorineFx端的Service
namespace ServiceLibrary
{
/// <summary>
/// Fluorine sample service.
/// </summary>
[RemotingService("Fluorine sample service")]
public class Sample
{
public Sample()
{
}
public string Echo(string text)
{
return "Gateway echo: " + text;
}
/// <summary>
/// 还有问题
/// </summary>
/// <returns></returns>
public Book GetBook()
{
return new Book
{
ID = 2,
Name = "让子弹飞一会",
Author = "姜文",
Price = 32
};
}
/// <summary>
/// 还有问题，不能传值
/// </summary>
/// <returns></returns>
