自己修改的方法

Public Function DownFile() As FileStreamResult
      Dim filePath As String = "C:TEMPbbb.txt"
      Dim fileName As String = "お願い.txt"
      Dim absoluFilePath As String = filePath 'Server.MapPath(System.Configuration.ConfigurationManager.AppSettings["AttachmentPath"] +   filePath)
      Return File(New System.IO.FileStream(absoluFilePath,System.IO.FileMode.Open),"application/octet-stream",Server.UrlEncode(fileName))
    End Function
