Just for the record   DirectoryInfo di   new DirectoryInfo currentDirName   FileInfo   smFiles   di GetFiles    txt    string fileNames   String Join       smFiles Select lt FileInfo  string gt  fi   gt  Path GetFileNameWithoutExtension fi FullName       This way you don t use StringBuilder but String Join    Also please remark that Path GetFileNameWithoutExtension   needs a full path  fi FullName   not fi Name as I saw in one of the other answers

As an additional answer  or to compound on the existing answers  you could write an extension method to accomplish this for you within the DirectoryInfo class  Here is a sample that I wrote fairly quickly that could be embellished to provide directory names or other criteria for modification  etc   using System  using System Collections Generic  using System IO  using System Linq  using System Text   namespace DocumentDistributor Library       public static class myExtensions               public static string   GetFileNamesWithoutFileExtensions this DirectoryInfo di                        FileInfo   fi   di GetFiles                List lt string gt  returnValue   new List lt string gt                  for  int i   0  i  lt  fi Length  i                                  returnValue Add Path GetFileNameWithoutExtension fi i  FullName                                return returnValue ToArray lt string gt                          Edit  I also think this method could probably be simplified or awesome-ified if it used LINQ to achieve the construction of the array  but I don t have the experience in LINQ to do it quickly enough for a sample of this kind   Edit 2  almost 4 years later   Here is the LINQ-ified method I would use   public static class myExtensions       public static IEnumerable lt string gt  GetFileNamesWithoutExtensions this DirectoryInfo di                return di GetFiles                Select x   gt  Path GetFileNameWithoutExtension x FullName

if file name contains directory and you need to not lose directory   fileName Remove fileName LastIndexOf

FileInfo knows its own extension  so you could just remove it  fileInfo Name Replace fileInfo Extension       fileInfo FullName Replace fileInfo Extension         or if you re paranoid that it might appear in the middle  or want to microoptimize   file Name Substring 0  file Name Length - file Extension Length

You can use Path GetFileNameWithoutExtension   foreach  FileInfo fi in smFiles        builder Append Path GetFileNameWithoutExtension fi Name        builder Append            Although I am surprised there isn t a way to get this directly from the FileInfo  or at least I can t see it

This solution also prevents the addition of a trailing comma   var filenames   String Join                                                Directory GetFiles   c        txt                           Select filename   gt                              Path GetFileNameWithoutExtension filename       I dislike the DirectoryInfo  FileInfo for this scenario   DirectoryInfo and FileInfo collect more data about the folder and the files than is needed so they take more time and memory than necessary

Path GetFileNameWithoutExtension file     This returns the file name only without the extension type  You can also change it so you get both name and the type of file   Path GetFileName FileName     source https   msdn microsoft com en-us library system io path v vs 110  aspx
