Asp.net 更改视图位置

我正在用MVC2.0开发一个网站。我想更改网站中的查看文件夹位置。我想把视图文件夹保存在其他文件夹中，当我尝试这样做时，我会遇到以下错误

The view 'Index' or its master was not found. The following locations were searched:
~/Views/Search/Index.aspx
~/Views/Search/Index.ascx
~/Views/Shared/Index.aspx
~/Views/Shared/Index.ascx
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

“我的视图”文件夹将位于~/XYZ/ABC/Views而不是~/Views中。请解决我的问题。如果我更改默认视图文件夹位置，是否会遇到任何问题。我是否需要更改HTML Helper类中的任何内容，因为我不知道MVC中的任何内容，因为这是我的开始项目，我不想冒险。请帮助我…

查看此位置

更简单的是这个

您需要创建一个自定义视图引擎并使用它。幸运的是，您可以从默认的构造函数继承并更改构造函数上的位置。以下是创建自己的视图引擎的指南：

从文章中：

protected void Application_Start()
{
    //... other things up here.

    // I want to REMOVE the ASP.NET ViewEngine...
    ViewEngines.Engines.Clear();

    // and then add my own :)
    ViewEngines.Engines.Add(new HoTMeaTViewEngine());
}

public class HoTMeaTViewEngine : VirtualPathProviderViewEngine
{
    public HoTMeaTViewEngine()
    {
        // This is where we tell MVC where to look for our files. This says
        // to look for a file at "Views/Controller/Action.html"
        base.ViewLocationFormats = new string[] { "~/Views/{1}/{0}.html" };

        base.PartialViewLocationFormats = base.ViewLocationFormats;
    }
}

或者，可以替代特定控制器的视图引擎位置，而不影响其他控制器的视图引擎

    #region Constructor
    public KBRenderMvcController()
        : base()
    {
        viewEngine = new KBFrontEndViewEngine();
        if (!this.ViewEngineCollection.Contains(viewEngine))
            this.ViewEngineCollection.Insert(0, viewEngine);
    }
    #endregion

public class KBFrontEndViewEngine : RazorViewEngine
{
    #region Fields
    private static bool _Initialized = false;
    private static string[] viewLocationFormats = null;
    private static string[] partialViewLocationFormats = null;
    private static string[] viewEngineFileExtensions = new string[] { "cshtml" };
    #endregion

    #region Constructor
    public KBFrontEndViewEngine()
    {            
        if (!_Initialized)
        {
            viewLocationFormats = new string[] 
                    { 
                        string.Concat(KBApplicationCore.PluginRelUrl, "/Views/{1}/{0}.cshtml"), 
                        string.Concat(KBApplicationCore.PluginRelUrl, "/Views/Partials/{0}.cshtml") 
                    };
            partialViewLocationFormats = new string[] 
                    { 
                        string.Concat(KBApplicationCore.PluginRelUrl, "/Views/{1}/Partials/_partial{0}.cshtml"), 
                        string.Concat(KBApplicationCore.PluginRelUrl, "/Views/Partials/_partial{0}.cshtml"),
                        string.Concat(KBApplicationCore.PluginRelUrl, "/Views/{1}/Dialogs/_dialog{1}.cshtml"),
                        string.Concat(KBApplicationCore.PluginRelUrl, "/Views/Dialogs/_dialog{1}.cshtml"),
                    };
            _Initialized = true;
        }
        base.ViewLocationFormats = viewLocationFormats;
        base.PartialViewLocationFormats = partialViewLocationFormats;
        base.MasterLocationFormats = viewLocationFormats;
        base.FileExtensions = viewEngineFileExtensions;
    }
    #endregion

    #region Methods
    //Don't run on requests that are not for our hijacked controllers
    public override ViewEngineResult FindPartialView(ControllerContext controllerContext, string partialViewName, bool useCache)
    {
        Type controllerType = controllerContext.Controller.GetType();
        Type baseType = controllerType.BaseType;
        if ((baseType != null) && (baseType.Name == "KBRenderMvcController`1") || (baseType.Name == "KBFrontEndBaseSurfaceController"))
            return base.FindPartialView(controllerContext, partialViewName, useCache);
        else
            return new ViewEngineResult(new List<string>());
    }
    #endregion
}

这些是我正在开发的产品中的一些片段，但它显示了我的一个控制器的构造函数，以及我为从KBRenderMvcController继承的控制器专门制作的视图引擎

因此，任何基于KBRenderMvcController的控制器也将具有我的视图引擎

然而，在任何时候我都没有清除视图引擎集合，这是相关的。因为我想让我的产品使用的视图返回到默认位置

简而言之，如果删除\App\u plugins\Product\Views\MyView并创建\Views\MyView，它仍将从\Views\MyView进行渲染

此外，在ViewEngine中，我演示了确定正在使用的控制器类型的代码，如果它不是目标控制器，我将返回空的视图位置，以便它们不会用于其他控制器

如果您不想全力以赴创建自己的ViewEngine，只需在App_Start:ViewEngines.Engines.Clear（）中的现有引擎上设置位置格式即可；添加（新WebFormViewEngine{LocationFormats=新字符串[]{“~/Views/{1}/{0}.html”}…}）；
