using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using TestClass;[WebService(Namespace = "http://lizq.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
[System.Web.Script.Services.ScriptService]public class Service : System.Web.Services.WebService
{public Service () {//如果使用设计的组件，请取消注释以下行 //InitializeComponent(); }[WebMethod]public string LoginUser(UserModel model){return new LoginService().LoginUser(model);}}

对于 传入的参数 UserMode  是我们自己建立的一个对象类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;namespace TestClass
{public class UserModel{private string userName;public string UserName{get { return userName; }set { userName = value;}}private string passWord;public string PassWord{get { return passWord; }set { passWord = value; }}}
}

最后就是把webservice 部署到IIS

  @Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Button loginButton=(Button)findViewById(R.id.button1);nameText=(EditText)findViewById(R.id.editText1);passText=(EditText)findViewById(R.id.editText2);StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder().detectDiskReads().detectDiskWrites().detectNetwork()   // or .detectAll() for all detectable problems
        .penaltyLog().build());StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder().detectLeakedSqlLiteObjects().detectLeakedClosableObjects().penaltyLog().penaltyDeath().build());loginButton.setOnClickListener(new OnClickListener(){@Overridepublic void onClick(View v) {// TODO Auto-generated method stub
                Login();}});if (savedInstanceState == null) {getFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment()).commit();}}

 protected void Login(){String nameSpace = "http://lizq.org/";String methodName = "LoginUser";String soapAction = "http://lizq.org/LoginUser";String url = "http://192.168.1.42:5179/Service.asmx?WSDL";//后面加不加那个?wsdl参数影响都不大//建立webservice连接对象org.ksoap2.transport.HttpTransportSE transport = new HttpTransportSE(url,30000);transport.debug = true;//是否是调试模式//设置连接参数SoapObject soapObject = new SoapObject(nameSpace, methodName);UserModel user=new UserModel();user.setProperty(0, nameText.getText().toString());user.setProperty(1, passText.getText().toString());PropertyInfo pi = new PropertyInfo();pi.setName("model");pi.setValue(user);pi.setType(user.getClass());soapObject.addProperty(pi);//将自定参数加入请求对象中//设置返回参数SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER12);//soap协议版本必须用SoapEnvelope.VER11（Soap V1.1）envelope.dotNet = true;//注意：这个属性是对dotnetwebservice协议的支持,如果dotnet的webservice 不指定rpc方式则用true否则要用falseenvelope.bodyOut = soapObject;//envelope.setOutputSoapObject(soapObject);//设置请求参数envelope.addMapping(nameSpace, "UserModel", user.getClass());//传对象时必须，参数namespace是webservice中指定的， name是服务器类型的名称， claszz是自定义类的类型try {transport.call(soapAction, envelope);Object sb = (Object)envelope.bodyIn;//服务器返回的对象存在envelope的bodyIn中Object us= (Object)envelope.getResponse();//直接将返回值强制转换为已知对象if(us.toString()==""){}} catch (IOException e) {// TODO Auto-generated catch block
         e.printStackTrace();} catch (XmlPullParserException e) {// TODO Auto-generated catch block
         e.printStackTrace();} catch(Exception ex){ex.printStackTrace();}return ;}
