也玩MVC3.“.NET研究”0 Razor自定义视图引擎来修改默认的Views目录结构

刚刚爱上MVC3.0，几个不眠夜的学习越来越有趣。今天随手尝试自定义Mvc3.0的视图引擎，虽然已成功，但是还发现有点小疑问。随手贴出来希望大家指教指教。

MVC的视图文件目录被固定/Views目录内，区域视图文件也是被固定在/Areas目录下，出于好奇和对目录名的敏感，尝试修改它。通过reflector找到视图引擎的构造接口类VirtualPathProviderViewEngine

在MVC2.0中，自定义自己的视图引擎，继承它即可，但在3.0中，上海企业网站制作我发现继承它会缺少一个函数。再reflector获得了BuildManagerViewEngine的抽象类，因为RazorViewEng上海企业网站设计与制作ine继承的是该抽象类。

所以最直接还是在自己的视图引擎中继承它。

上面是原Razor视图引擎的构造类，我只是拷贝下来修改修改我希望的目录结构，比如将原Views目录改成了T，然后在程序初始化的时候，注册加入这个自己的视图引擎类。

ViewEngines.Engines.Clear();
ViewEngines.Engines.Add(new myVi上海徐汇企业网站设计与制作ewEngine());

将项目中Views目录改名T，调试成功。这样，以后的目录结构我们自己可以任意定义。非常方便。

但是，有人可能会说那6个目录定义属性都是public的，可以直接调出来修改，结果我也这样试过，没成功，无论我直接调用RazorViewEngine封装，还是VirtualPathProviderViewEngine继承后为属性设定值。都没成功，可能我的方法有问题。 如果你知道，希望可以告诉我。

另外这样自定义目录结构后，在View和Controller之间不能定位了，VS环境还是认为Views目录是视图文件目录，自己定义的T目录没有了“脚手架”...
