皮肤问题!

vs2008 
c#.net c/s 
下了套皮肤 放在桌面  (工程放在其他地方了) 
然后我添加选项卡是从桌面选的!加完后就删了 
我又考了1个文件 DiamondGreen.ssk(是皮肤吧) 
放在了工程里bin/Debug里了! (DiamondGreen.ssk因该是在工程里了)
然后把皮肤拖出来用 
代码这样写的:(下面几个写法都在调试的时候有效果 就是安装后没有)
        public landing()
        {
            InitializeComponent();
            this.skinEngine1.SkinFile = "inform_fgw/bin/Debug/DiamondBlue.ssk";
        }
 -------------------
        public landing()
        {
            InitializeComponent();
            this.skinEngine1.SkinFile = "DiamondBlue.ssk";
        }
--------------------
        public landing()
        {
            InitializeComponent();
            this.skinEngine1.SkinFile = "/Debug/DiamondBlue.ssk";
        }
-------------------
        public landing()
        {
            InitializeComponent();
            this.skinEngine1.SkinFile = "/bin/Debug/DiamondBlue.ssk";
        }
----------------------郁闷的是这样写都在调试时有效果(只是编译没通过)
        public landing()
        {
            InitializeComponent();
            this.skinEngine1.SkinFile = "DiamondBlue.ssk
        }调试有效果 
然后安装了就没效果了!!!??? 
请高手指点
