Delphi调用WebServices(C#)代码

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

using System.Data;
using System.Data.OracleClient;
using System.IO;

using System.IO.Compression;
using System.Runtime.Serialization.Formatters.Binary;
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class Service : System.Web.Services.WebService
}

以上为webservice客户端代码；下面是delphi代码：

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, InvokeRegistry, Rio, SOAPHTTPClient, ExtCtrls, StdCtrls,
  Service,types,jpeg,StrUtils, Buttons;
  //StrUtils:取指定字符
  {QDialogs:在delphi6及以后的版本中,
  为了支持kylix,能使程序在linux下运行
  每一个单元都增加了对应的QDialogs单元
  如果你用了带Q的单元,哪么如果你的程序
  要想在Windows中正常运行必须得有qtintf.dll
  的支持你可以搜索一个,把程序中uses中的
  单元前有Q的把Q去掉就ok了!   }
