我一直在尝试几天，以便使.NET客户端能够充分使用我的基于Coldfusion的Web服务器提供的web应用程序。我本身并不是一个.NET开发人员，但我碰巧拥有一份VS 2003的副本，这看起来应该可以做到。从.NET调用基于AXIS的Web服务时，嵌套的复杂类型元素永远不会被填充
我可以在我的web服务中使用一个简单的乘法器（）方法，它接受两个数字并返回一个数字，所以简单的类型工作正常。这是复杂的类型，正在杀死我。我基本上试图从一个名为get_struct（）的方法返回一个关联数组。我得到一个Map返回类型的对象，但属性（称为item），应该是一个具有两个元素（类型为mapItem）的数组，总是有一个“未定义的值”。
这里是由ColdFusion的生成WSDL：

最后，我的CLI应用程序，测试服务：
using System;
namespace pfapi_test
{
/// <summary>
/// Summary description for Class1.
/// </summary>
class Class1
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
//
// TODO: Add code to start application here
//
Console.WriteLine("Instantiating WS");
remote_io_test.remote_io_testService testWS = new remote_io_test.remote_io_testService();
Console.WriteLine("Calling multiplier(3,15)");
Console.WriteLine(testWS.multiplier(3,15));
Console.WriteLine("Calling get_struct()");
remote_io_test.Map theStruct = testWS.get_struct();
Console.Write("result: ");
Console.WriteLine(theStruct);
Console.Write("result.item: ");
Console.WriteLine(theStruct.item);
Console.WriteLine("Press Enter to exit...");
Console.ReadLine();
}
}
}
无论我尝试什么，theStruct.item总是“undef根据调试器的不同，可以得到一个“值”。打印输出如下：
Instantiating WS
Calling multiplier(3,15)
45
Calling get_struct()
result: pfapi_test.remote_io_test.Map
result.item:
Press Enter to exit...
我试过使用ColdFusion 8，并没有区别。我试过返回一个真正的自定义数据库与两个属性，而不是我的临时关联数组，而且工作正常，但重写我的API以避免关联数组目前不是一个真正的选择。这个API可以在ColdFusion，PHP/NuSOAP和Ruby on Rails上正常工作，所以它似乎也应该可以让它与.NET一起工作。
我希望有人能提供一些见解。我怀疑这里存在某种名称空间问题，但我不清楚SOAP和XML是否足够清楚它是什么。我也在网上疯狂搜索解决方案，但我还没有找到解决此问题的单个人，这非常令人沮丧！

更新：我从另一端的.NET开发人员听到了，他尝试了所有的以下无济于事的：
- 使用WCF而不是ASMX
- 使用.NET 3.5
- 使用VB.NET与Web服务，而不是C＃
沟通，他送我的服务引用设置对话框的“数据类型”部分的截屏。是否有可能更改集合类型和Dictionary集合类型的设置可以解决此问题？

感谢您的阅读，并在此先感谢您的答复！在link text
有你，如果确定这是服务器还是客户端问题？ （是否有任何其他软件客户端成功调用get_struct（）？） – 2009-12-17 22:45:02
您可以添加一个简单的ColdFusion代码示例，您的.net应用程序正在进行测试，因此我们中的一些人可以对其进行测试吗？ – kevink 2009-12-18 06:42:32
@Dan Sorensen，谢谢你的提问。我有Coldfusion，PHP和Ruby on Rails客户端在我的真实API中成功发送和接收结构。这个Web服务用于人们开始使用API时的互操作性测试。 – sbleon 2009-12-18 19:30:33
