.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。
