在C＃中的SOAP客户端无法获得一个WSDL文件 [英] SOAP Client in C# without access to a WSDL-file

问题描述

我正在与第三方来整合我们的一些系统与他们的，他们为我们提供了一个SOAP接口做出一定的要求和改变其连接的系统。对我来说，问题是，他们不提供一个WSDL文件，我对着干。如果我有一个WSDL文件这将是一件简单的事只是为了运行所提供的.NET命令（Wsdl.exe用），并生成一个代理类与服务进行交互。

有一个简单的方式来做到这一点没有一个WSDL文件？我有所有我们可以访问，我需要送什么参数，我应该想到回报的功能。

它是常见的有没有用WSDL文件的SOAP服务？ （我问这个，因为我们将增加更多的外部系统成未来混合）

有没有人做代理类或针对WDSL无服务的任何其他形式的客户端，并且对如何做到这一点任何好的指针？

I'm working with a third party to integrate some of our systems with theirs and they provide us with a SOAP interface to make certain requests and changes in their connected systems. The problem for me is that they do not supply a WSDL-file for me to work against. If I had a WSDL-file it would be a simple matter just to run the supplied .NET command (wsdl.exe) and generate a proxy class to interact with the service.

Is there an "easy" way to do this without a WSDL-file? I have all the functions that we can access and what parameters I need to send and what I should expect in return.

Is it common to have a SOAP-service without WSDL-files? (I'm asking this since we're going to add more external systems into the mix in the future)

Has anyone done a proxy-class or any other form of client against a WDSL-less service and have any good pointers on how to do it?
