need to use some specific files from each folder of a dir.

Question

hi I have two directories and every directories represent the data acquired from a software with thesame names of folders and files name. i wanna use these files to compare with each other. What i need is a function or a method which can get me some files based on their names one i select the folder. I used FolderBrowseDialog to select the folder and used openfileDialog to open the files but instead of openfiledialog i would need another function that can automatically select particular files of that folder. I had tried Directory.getfiles but can i select the files that i need based on their names(files).any filter that i can use.

I think you may need regex. Assuming that you want to select the files with same name as directory name try below code. I created directory named TestFiles and placed around 5 to 6 files where some of the files names were startting with TestFiles and others were not. Variable Files would contain the list of files that matches the regex pattern. DirectoryInfo dinfo = new DirectoryInfo( Drive:\somefolder\TestFiles ); string DirName = TestFiles ; Regex pattern = new Regex($ ^{DirName}\w ); var Files = dinfo.GetFiles().Where(file => pattern.IsMatch(file.Name) == true );

Thank you Tapan it was very helpful it works upto some extent. The folders and files are like this. Ver 1.1 [ABC( adlam.dbf alaam.dbf trends.dbf pages.dbf variables.dbf................)] (dir.) (dir ) (.........................................Files.........................................................) Ver 1.2 [ABC( adlam.dbf alaam.dbf trends.dbf pages.dbf variables.dbf................)] the files names are in uppercases in some folders. I had used conditional loops for it as i could not find any method to serve the purpose. it is lengthy but working. and i thank both of you for your help and i appreciate your time. Regards

As per my knowledge you can't select aprticular but you can avoid with file extension like : openFileDialog1.FileName = test*; openFileDialog1.Filter = Test Files|*.pdf; https://msdn.microsoft.com/fr-fr/library/system.windows.controls.openfiledialog.filter(v=vs.95).aspx

You can use SelectedPath property to provide default path for broswe dialogue. FolderBrowserDialog diag = new FolderBrowserDialog(); diag.Description = Select a folder in which to save your workspace... ; folderBrowserDialog1.SelectedPath = @ c:	emp\ ; folderBrowserDialog1.ShowDialog();

have tried already but can not use openfilefolder as i need the files to be selected automatically by selecting folder. Directory.getfiles works but need to further filter it down to 7 files on their name basis. but thank you very much for your response it was helpful.

Thank you Manas for your reply but i need a function that can select particular files automatically once i select the folder with folderBrowseDialog. i was using Directory.getFiles to get these files into an array but the filter in this is only on extension basis not by name of the file. can you suggest me anything that will help.
