.Net 2.0 WebService传递参数的问题

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Xml;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
//[WebServiceBinding(ConformsTo = WsiProfiles.None)]
//[SoapRpcService(RoutingStyle = SoapServiceRoutingStyle.soapAction)]

public class Service : System.Web.Services.WebService
{
    public Service () {

        //Uncomment the following line if using designed components
        //InitializeComponent();
    }

    [WebMethod]
    public string HelloWorld() {
        return "Hello World";
    }
    [WebMethod(Description = "加法测试")]
    public  int Count(int x,int y)
    {
        return x + y;
    }
    [WebMethod(Description = "上传测量记录")]
    public int Upload(string data)
    {
        return 1;
    }
  
}

如果红字部分打开，则是采用RPC方式传递参数，缺省的BCB就是这样处理的，否则是采用Document|Literal 方式传递，BCB自动生成的代码要加上InvRegistry()->RegisterInvokeOptions(__interfaceTypeinfo(ServiceSoap),iodocument);才可以正确传递参数。
