如何从webservice中检索数据 [英] How to retrive data from webservice

问题描述

您好！



有人可以向我解释如何从桌面应用程序中的SAOP webservice中检索数据！



我有一段代码但是没有用！



网络服务包含搜索数据的查询！



我不知道怎么做？





请帮帮我？

解决方案

请参阅我对该问题的评论。你的代码没有任何意义。



你需要：

• 使用WDSL.EXE创建一个C＃中服务的代理代码： http://msdn.microsoft.com/en-us/library/ 7h3ystb6.aspx [ ^ ];
• 在生成的代码中，找到派生自类 System.Web.Services.Protocols.SoapHttpClientProtocol 的类;这是您需要实例化的类;
• 实例化它;
• 通过代理实例，调用Web方法。

如果问题不明确，请在询问下一个问题之前：

• 搜索： http://bit.ly/T24XqT [ ^ ];
• 了解Web服务：
  
  http://en.wikipedia.org/wiki/Web_services [ ^ ]，
  
  http://en.wikipedia.org/wiki/SOAP [ ^ ]，
  
  < a href =http://en.wikipedia.org/wiki/WSDL> http://en.wikipedia.org/wiki/WSDL [ ^ ];
• l至少获得编程的基础知识：类型和实例（对象）;类，结构和接口，接口实现，以及......更多。

解决方案

Please see my comments to the question. Nothing makes any sense in your code.

You would need to:

• Use WDSL.EXE to create a proxy code for a service in C#: http://msdn.microsoft.com/en-us/library/7h3ystb6.aspx[^];
• In the generated code, locate the class derived from the class System.Web.Services.Protocols.SoapHttpClientProtocol; this is the class you need to instantiate;
• Instantiate it;
• Through the instance of the proxy, invoke Web methods.

If something is not clear, before asking your next question:

• Search: http://bit.ly/T24XqT[^];
• Learn about Web services:
  http://en.wikipedia.org/wiki/Web_services[^],
  http://en.wikipedia.org/wiki/SOAP[^],
  http://en.wikipedia.org/wiki/WSDL[^];
• learn at least the very basics of programming: types and instances (object); classes, structures and interfaces, interface implementations, and… a lot more.
