string SayHello(string words)
   
{
      
return
"Hello "
+ words;
   
}
  
}
}

2. 构建IIS网站宿主

  YourService.svc

<%@ServiceHost Debug=”true” Service=”YourNameSpace.YourService”%>

  Web.config

3. 寄宿服务

  把网站发布到web服务器, 指定网站虚拟目录指向该目录

  如果你能够访问http://你的IP:端口/虚拟目录/服务.svc

  那么,恭喜你,你的服务端成功了! 

4. 使用ksoap2调用WCF

  去ksoap2官网

  http://code.google.com/p/ksoap2-android/ 下载最新jar

 5. 在Eclipse中新建一个Java项目,测试你的服务

  新建一个接口, 用于专门读取WCF返回的SoapObject对象

  ISoapService

安卓（Android）开发：利用ksoap2调用webservice服务，并自动生成客户端代理类代码

安卓调用Webservice和Java稍有不同，利用的是ksoap2这个jar包。之前这个jar包是发布在googlecode上面的目前项目已经移动到了github.io，我这里贴上的github官方网站，我也不知道这个github.io和github.com是不是一回事。我们可以在以下页面看到项目的总览：http://simpligility.github.io/ksoap2-android/index.html。

 

1.下载ksoap2jar包

在如下页面进行下载：https://oss.sonatype.org/content/repositories/ksoap2-android-releases/com/google/code/ksoap2-android/ksoap2-android-assembly/

ksoap2项目的源码在这里，有兴趣的可以弄下来研究哦：

https://github.com/simpligility/ksoap2-android/

2.在Android Studio中进行配置

这一步简单，先放到lib文件夹下，然后再lib上点击右键，选择ADD AS LIB就可以了哦

3.利用网上的服务，自动生成ksoap2可用的webservice的客户端代理类

打开http://www.wsdl2code.com/pages/Home.aspx页面，在页面的右边填入你的webService的访问地址，然后选择生成的方式，我选的是Android Using kSoap2.如果你的webservice还没有发布，也可以直接上传其wsdl文件。

点击submit，此时要求登录，如果没有账号就注册一个，然后登陆，稍等一会这个工具就会为我们自动生成Webservice客户端代理类的代码了，点击下载

image

当然，自动生成的没有与jar运行环境啊什么的，可能使用的时候有些问题，至少包命名就得改成你自己的，所以，我们再简单的修改一下这些代码就可以直接使用了，省去了我们手动写客户端代理类的麻烦，是不是很方便啊。
