Siebel生成了WSDL输入参数顺序和Visual Studio生成的代码

I consume a .wsdl file for a webservice developped by a Siebel team in my company. The generated code by Visual Studio when I update the service reference has changed lately which means I'll have to rewrite some code for the calling methods in the application. Indeed, the order of the input parameters have changed for some of the webservice methods. It is visible in the .wsdl itself, the "part name" are not in the order they used to be.I consume a .wsdl file for a webservice develop
