推荐答案

由于您有WSDL（感谢您回答我的问题），除了服务本身之外，这就是您所需要的。请参阅：

http://en.wikipedia.org/wiki/WSDL [< a href =http://en.wikipedia.org/wiki/WSDLtarget =_ blanktitle =New Window> ^ ]。



基本上，您使用wsdl.exe实用程序为服务创建存根： http://msdn.microsoft.com/en-us/library/7h3ystb6%28v=vs.100%29.aspx [ ^ ]。



你创建一个生成的存根并在你的项目中使用它。

As you have WSDL (thank you for answering my question), this is all what you need, in addition to the service itself. Please see:
http://en.wikipedia.org/wiki/WSDL[^].

Basically, you create a stub for the service using the "wsdl.exe" utility: http://msdn.microsoft.com/en-us/library/7h3ystb6%28v=vs.100%29.aspx[^].

You create a stub generated and use it in your project.

Here is the short walk-through manual: http://www.sitepoint.com/net-web-services-5-steps-2/[^].

You can find many other samples or descriptions of the steps on the Web, please see: http://bit.ly/1hvDidt[^].

从Web服务返回的数据应该是JSON格式。因为几乎所有支持数据传输的语言都支持JSON。

然后您可以轻松使用跨语言Web服务。

The data return from the web service should be in the JSON Format. Because almost all language which are support data transmission are supporting the JSON.
Then you can easily consume the cross language web service .
