How to pick specific files from folder

Rajkumar R

Hi,
My application will generate export file name as abc_yyyyMMdd.xml and this file will be placed in one output path. I want to pick all file abc_ not abcabc_.
Here I need to select all the filename relevant to abc_ using regular expression matching pattern.
Please post solution for this post.
Thanks in Advance

try below code:

string dirPath = @"c:\dirName";
string[]fileNames = Directory.GetFiles(dirPath).Where(i => i.LastIndexOf("\\abc_")>-1).ToArray();

Try this:

string dirPath = @"c:\whatever";
string r = @"^[a-zA-Z]{3}_\d{8}\.xml$";
string[] fileNames = Directory.GetFiles(dirPath).Where(f => Regex.IsMatch(Path.GetFileName(f), r)).ToArray();
