如何在mvc的整個視圖文件夾中搜索任何單詞

Question

我的MVC項目的檢視資料夾中有許多.cshtml網頁。 在我的布局頁面中，有可用的搜索選項，因此當某人按任何單詞搜索時，我想在所有.cshtml頁面中搜索該單詞並返回視圖名稱。 我如何在MVC中實現這一目標？

一種可能的方法是：

string path = Server.MapPath("~/Views"); //path to start searching.
if (Directory.Exists(path))
{
    ProcessDirectory(path);
}
//Loop through each file and directory of provided path.
public void ProcessDirectory(string targetDirectory)
{
     // Process the list of files found in the directory.
     string[] fileEntries = Directory.GetFiles(targetDirectory);
     foreach (string fileName in fileEntries)
     {
          string found = ProcessFile(fileName);
     }
     //Recursive loop through subdirectories of this directory.
     string[] subdirectoryEntries = Directory.GetDirectories(targetDirectory);
     foreach (string subdirectory in subdirectoryEntries)
     {
          ProcessDirectory(subdirectory);
     }
}
//Get contents of file and search specified text.
public string ProcessFile(string filepath)
{
    string content = string.Empty;
    string strWordSearched = "test";

    using (var stream = new StreamReader(filepath))
    {
         content = stream.ReadToEnd();
         int index = content.IndexOf(strWordSearched);
         if (index > -1)
         {
              return Path.GetFileName(filepath);
         }
     } 
 }
