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

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

调用WCF验证登陆

    public class ActivityLogin : Activity
    {
        protected override void OnCreate(Bundle bundle)

            SetContentView(Resource.Layout.Login);

总之，大概就这样了，页面布局什么的也没什么特别的。

        <LinearLayout

            <Button

                android:text="登录" />
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

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);
    }
