在Visual Basic 2010 Express中使用WSDL [英] Consume a WSDL in Visual Basic 2010 Express

问题描述

您好群组。我试图在Visual Basic Express 2010中使用WSDL文件。 我已经将WSDL添加为Web引用，并且可以实例化一个对象来调用SOAP服务。 我还可以实例化响应和请求对象，所有在Visual Studio生成的reference.vb类中都定义了
。 我遇到的问题是由Visual Studio生成的对象构建的实际xml请求不包含任何标头信息（它应该具有用户名和密码），因此SOAP
服务拒绝我的请求和消息"用户名丢失"。 我已经在Visual Studio生成的请求和服务所需的实际请求以及提供给我的WSDL文件下面发布了。 由于我是新手，
我不知道我是否做错了，如果VS解释WSDL错误，或者WSDL文件有问题。 这是来自第三方的常用WSDL文件，因此我发现很难相信它有问题。 
我更改了名称空间和一些元素名称以保持通用。

Hi.  I am trying to consume a WSDL file in Visual Basic Express 2010.  I have added the WSDL as a web reference, and can instantiate an object to make calls to the SOAP service.  I can also instantiate response and request objects, all defined in the Visual Studio generated reference.vb class.  The problem I am having is that the actual xml request built by the Visual Studio generated object does not contain any header information (it is supposed to have a username and password), so the SOAP service rejects my request with the message "Username is missing".  I have posted below the Visual Studio generated request and the actual request that the service needs, as well as the WSDL file that was provided to me.  Since I am new to this, I don't know if I am doing something wrong, if VS is interpreting the WSDL wrong, or if there is a problem with the WSDL file.  This is a commonly used WSDL file from a 3rd party, so I find it hard to believe that it has a problem.  I have changed the namespaces and some element names to remain generic.

非常感谢任何帮助或指示。

Any help or direction is greatly appreciated.

这是WSDL文件：
