                test.Add(i);
                String[] filenames = (String[])test.ToArray(typeof(string));

This String[] filenames contains the list of file names.

Have you tried if (filenames.Contains(yourfilename)) ?

Not clear: does the array filenames contain full path names or file names without directory? In either case, what's the problem?

Solution 1

Please use System.IO.File.Exist:
http://msdn.microsoft.com/en-us/library/system.io.file.exists.aspx[^].

(Please see my comment to the question. You either pass each file name to this method, or combine it with the full path name of the directory in question.)

Solution 2

Here are a couple of links that provide solutions -

http://codingcluster.blogspot.in/2011/10/check-if-file-exists-using-c.html[^]
http://www.dotnetperls.com/file-exists[^]

You can in addition, try exploring FileInfo.Exists()[^] as well.

Same thing; we probably were writing at the same time; a 5.

Thanks SA. Note that I've mentioned FileInfo.Exists as well. :)

Sergey Alexandrovich Kryukov 27-Jul-12 16:41pm

Noted. Well, not exactly the same things. :-)

Here is a very short sample:

C#

private void button1_Click(object sender, EventArgs e)
{
   string[] filenames = new string[4];
   filenames[0] = "test.txt";
   filenames[1] = "test.txt";
   filenames[2] = "test2.txt";
   filenames[3] = "test3.txt";
   string strPath = @"C:\Temp\";
   foreach(string str in filenames)
   {
      if (!File.Exists(strPath + str))
         MessageBox.Show("File: " + str + " does not exist in folder: " + strPath);
   }
}

check if Files in directory
