File.Exists - Don't know name

Is it possible to copy a file that matches a certain NAME pattern - not extension!

for example, lets say I wanted to copy all files from c:\temp whose name starts with "FOO"

So here is my c:\temp directory:
FOO.txt
FOOBAR.pdf
FORGET_IT.doc


So in this case, I would need to get back: FOO.txt and FOOBAR.pdf

How can I do this?

thanks!!

Hi, you can have something like the following

using System.IO;
...

      string[] files = Directory.GetFiles(@"c:\temp", "FOO*");

      foreach (string filePath in files)
      {
            File.Copy(...); // use filePath here
      }

GetFiles() returns a string array of filepaths that match the pattern (specified in second parameter)

Alternatively, you can also instantiate a FileInfo object based on a filepath and do some tests on its useful properties to get the files you want:

      string[] files = Directory.GetFiles(@"c:\temp");
      FileInfo fi;

      foreach (string filePath in files)
      {
            fi = new FileInfo(filePath);
      
            if (fi.Name.StartsWith("FOO") && fi.Name.EndsWith("txt"))
            {
                  File.Copy(fi.FullName, "<destinarion path here>");
            }
      }

      fi = null;
