也玩MVC3.0 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,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RazorViewEngine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。

  

代码
public class myViewEngine : BuildManagerViewEngine
{

// Fields
internal static readonly string ViewStartFileName = "_ViewStart";

// Methods
public myViewEngine()
:
this(null)
{
}

public myViewEngine(IViewPageActivator viewPageActivator)
:
base(viewPageActivator)
{
base.AreaViewLocationFormats = new string[] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/{1}/{0}.vbhtml", "~/Areas/{2}/Views/Shared/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.vbhtml" };
base.AreaMasterLocationFormats = new string[] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/{1}/{0}.vbhtml", "~/Areas/{2}/Views/Shared/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.vbhtml" };
base.AreaPartialViewLocationFormats = new string[] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/{1}/{0}.vbhtml", "~/Areas/{2}/Views/Shared/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.vbhtml" };

base.ViewLocationFormats = new string[] { "~/T/{1}/{0}.cshtml", "~/T/Shared/{0}.cshtml" };
base.MasterLocationFormats = new string[] { "~/T/{1}/{0}.cshtml", "~/T/Shared/{0}.cshtml" };
base.PartialViewLocationFormats = new string[] { "~/T/{1}/{0}.cshtml", "~/T/Shared/{0}.cshtml" };

base.FileExtensions = new string[] { "cshtml", "vbhtml" };
}

protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)
{
string layoutPath = null;
bool runViewStartPages = false;
IEnumerable
<string> fileExtensions = base.FileExtensions;
return new RazorView(controllerContext, partialPath, layoutPath, runViewStartPages, fileExtensions, base.ViewPageActivator);
}

protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)
{
string layoutPath = masterPath;
bool runViewStartPages = true;
IEnumerable
<string> fileExtensions = base.FileExtensions;
return new RazorView(controllerContext, viewPath, layoutPath, runViewStartPages, fileExtensions, base.ViewPageActivator);
}


}

 

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 myViewEngine());

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”...
