asp.net-mvc-3 – 来自控制器的ASP.NET MVC3 View的物理位置

这是您可以使用的扩展方法：

public static class PhysicalViewPathExtension
{
    public static string GetPhysicalViewPath(this ControllerBase controller,string viewName = null)
    {
        if (controller == null)
        {
            throw new ArgumentNullException("controller");
        }

        ControllerContext context = controller.ControllerContext;

        if (string.IsNullOrEmpty(viewName))
        {
            viewName = context.RouteData.GetRequiredString("action");
        }

        var result = ViewEngines.Engines.FindView(context,viewName,null);
        BuildManagerCompiledView compiledView = result.View as BuildManagerCompiledView;

        if (compiledView != null)
        {
            string virtualPath = compiledView.ViewPath;
            return context.HttpContext.Server.MapPath(virtualPath);
        }
        else
        {
            return null;
        }
    }
}

使用这样的东西：

public ActionResult Index()
{
    string physicalPath = this.GetPhysicalViewPath();
    ViewData["PhysicalPath"] = physicalPath;
    return View();
}

要么：

public ActionResult MyAction()
{
    string physicalPath = this.GetPhysicalViewPath("MyView");
    ViewData["PhysicalPath"] = physicalPath;
    return View("MyView");
}
