Mono的简单例子

一直对移动端开发有些兴趣，但苦于不会Java，好在终于找到了个好玩的。

安装方法略了，先建立一个玩玩

Mono的简单例子

不多说，贴代码了，需要注意的只有些JAVA和C#写法不太一样的地方，不细介绍了，因为没什么经验，乱试的，所以也没什么规范，随便看看就好

总之，大概就这样了，页面布局什么的也没什么特别的。

至于服务端，就是VS自动生成的代码加了一个登陆判断而已

[ServiceContract]

    public interface IHotelService

    {

        [OperationContract]

        string Login(string user, string password);

    }
