获取java.lang.IllegalArgumentException:C#.net web服务调用中的参数类型不匹配

我需要从我的c#asp.net web应用程序调用Java web服务。我有以下方法的wsdl信息，并生成了代理类

有什么问题吗？有人能帮我解决吗

附言：我从wsdl中删除了一些对象，以通过必要的细节最小化页面大小。

您是否检查了submitPreApprovalApplication函数的签名。您确定参数的类型为SubmitPreApprovalApplicationRequest@MicrosoftPS我只得到了wsdl和webservice url。它是由其他人创建的，我看不到代码。但您可以在WSDL文件中看到它

       ApplicationServiceService service = new ApplicationServiceService();

       string version=  service.getVersion(); // This call works and fetches version

       service.Credentials = System.Net.CredentialCache.DefaultCredentials;
       SubmitPreApprovalApplicationRequest req = new SubmitPreApprovalApplicationRequest();
           req.prop=value// preparing all the properties

       res = service.submitPreApprovalApplication(req); //HERE IS THAT ERROR
