Return MVC View that matches Param File Name in Parent Folder and Sub-Folders

Question

I want to return an MVC view based on the filename passed into the controller function. However, the following requires a relative path:

[Route("/ReturnViewByFileName/{ViewName}")]
public ActionResult ReturnViewByFileName(string FileName)
{
    return View("~/RelativePath");
}

Since I want to find a view file that is based on the parameter file name and I want to search a particular folder and sub folders for that file name.

var path = CurrentEnvironment.ContentRootPath + "\\Views\Parentfolder";

string[] FindFile = Directory.GetFiles(path, "*" + FileName + 
"*", SearchOption.AllDirectories);

The problem is, this gives you the full file path of the file and not the relative file path that View() requires.

Is there a simple way to do one of the following:

1. Override the View() function to accept a full file path
2. Convert a full file path name to a relative file path

3. Or something else I am overlooking

   Solution

   public ActionResult FindMVCView(string FileName)
   {
   var path = CurrentEnvironment.ContentRootPath + "\\ParentFolder";
   
   string[] FindFile = Directory.GetFiles(path, "*" + FileName +
   "*", SearchOption.AllDirectories);
   
   var newpath = FindFile[0].Replace(CurrentEnvironment.ContentRootPath, 
   "~/").Replace(@"\", "/");
   }
