Adding a search location in ASP.NET Core's ViewEngineExp

我读过几篇教程，解释了在需要移动视图文件夹的情况下，如何替换视图文件夹的默认路径。然而，我一直在试图找出如何添加视图引擎搜索的路径。

到目前为止，我拥有的是：

public class BetterViewEngine : IViewLocationExpander
{
    public void PopulateValues(ViewLocationExpanderContext context)
    {
    }
    public IEnumerable<string> ExpandViewLocations(ViewLocationExpanderContext context, IEnumerable<string> viewLocations)
    {
        return viewLocations.Select(s => s.Add("")); //Formerly s.Replace("oldPath", "newPath" but I wish to add
    }
}

在我的Startup.cs中

services.AddMvc().AddRazorOptions(options =>
        {
            options.ViewLocationExpanders.Add(new BetterViewEngine());
        });

如果您想更改搜索视图的默认行为，请尝试以下操作：

public class BetterViewEngine : IViewLocationExpander
{
   public void PopulateValues(ViewLocationExpanderContext context)
   {
        context.Values["customviewlocation"] = nameof(BetterViewEngine);
   }
   public IEnumerable<string> ExpandViewLocations(
        ViewLocationExpanderContext context, IEnumerable<string> viewLocations)
   {
        return new[]
        {
             "/folderName/{1}/{0}.cshtml",
             "/folderName/Shared/{0}.cshtml"
        };
   }
}

但如果你只想重命名其中一个文件夹，试试这个：

public IEnumerable<string> ExpandViewLocations(
      ViewLocationExpanderContext context, IEnumerable<string> viewLocations)
{
      // Swap /Shared/ for /_Shared/
      return viewLocations.Select(f => f.Replace("/Shared/", "/_Shared/"));
}

这只是对Sirwan的答案的扩展，因为在阅读了他的答案的第一部分后，我花了一分钟的时间来弄清楚我需要做什么：

public class ViewLocationRemapper : IViewLocationExpander
{
    public IEnumerable<string> ExpandViewLocations(ViewLocationExpanderContext context, IEnumerable<string> viewLocations)
    {
        return new[]
        {
            "/Views/{1}/{0}.cshtml",
            "/Views/Shared/{0}.cshtml",
            "/Views/" + context.Values["admin"] + "/{1}/{0}.cshtml"
        };
    }
    public void PopulateValues(ViewLocationExpanderContext context)
    {
        context.Values["admin"] = "AdminViews";
    }
}
