你如何为ASP.NET MVC编写自己的View引擎？

public class CustomViewEngine : ViewEngine
{
    public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache)
    {
        // 在这里实现自己的视图查找逻辑
        var viewPath = Path.Combine(controllerContext.HttpContext.Server.MapPath("~/Views"), viewName + ".cshtml");
        var view = new RazorView(controllerContext, viewPath, null, false, null);
        return new ViewEngineResult(view, this);
    }

    public override ViewEngineResult CreatePartialView(ControllerContext controllerContext, string partialViewName, bool useCache)
    {
        // 在这里实现自己的部分视图创建逻辑
        var viewPath = Path.Combine(controllerContext.HttpContext.Server.MapPath("~/Views"), partialViewName + ".cshtml");
        var view = new RazorView(controllerContext, viewPath, null, false, null);
        return new ViewEngineResult(view, this);
    }

    public override ViewEngineResult CreateView(ControllerContext controllerContext, string viewName, string masterName, bool useCache)
    {
        // 在这里实现自己的完整视图创建逻辑
        var viewPath = Path.Combine(controllerContext.HttpContext.Server.MapPath("~/Views"), viewName + ".cshtml");
        var view = new RazorView(controllerContext, viewPath, null, false, null);
        return new ViewEngineResult(view, this);
    }
}

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    ViewEngines.Engines.Clear();
    ViewEngines.Engines.Add(new CustomViewEngine());
    // 其他代码
}
