find files

michaelgr1

Hello, How i can search for a particular gif file (and open it) in a particular directory. I need the search to be recusive, i mean there are many folders in this directory and in each directory other folder and so on. I need the program to search in all those directories for this file. How can i do it?

// c:\MyDir\ is your parent Directory ....
string[] filePaths = Directory.GetFiles(@"c:\MyDir\", "*.gif",
SearchOption.AllDirectories);

I know nothing , I know nothing ...

well like you said, write a recursive function. Basic idea...

using System.IO;

string FindFile(string initDirectory, string fileToFind)
{
DirectoryInfo dir = new DirectoryInfo(initDirectory);
foreach(FileInfo file in dir.GetFiles())
{
if(file.Name == fileToFind)
return file.FullName;
}
foreach(DirectoryInfo subDir in dir.GetDirectories())
{
return FindFile(subDir.FullName, fileToFind);
}
return null;
}

..that should do the trick, if not I hope you get the idea

Hello, This code gives me the following errors: Error Cannot convert to static type 'System.IO.Directory' Error Cannot convert type 'System.IO.DirectoryInfo' to 'System.IO.Directory' Error The name 'FindFile' does not exist in the current context Error 'System.IO.Directory' does not contain a definition for 'Fullpath'

see edited code... thou you should have been able to fix those mistakes yourself. The error messages are very straight forward.

I'm sorry, I fixed those errors myself , but it still doesn't work properly as i need. it enters only the subdirectories of the first directory (in the initdirectory) and so on. If i have many directories in the main directory (initdirectory) and so on in the other subdirectories it doesn't work. Of course if the file is located somewhre there in the subdirectories of the subdirectories...

Not seen that before and have always written a recursive procedure for this sort of thing. Does this work?

hmmm.. post the code you are using

I used exactly the code you wrote. but it doesn't searches in the directories as i need (as i wrote in the previous post)

michaelgr1

Also i tries this way- private void dirsearch(string Start_dir, string search) { MessageBox.Show(search); try { foreach (string d in Directory.GetDirectories(Start_dir)) { MessageBox.Show(d); foreach (string f in Directory.GetFiles(Start_dir)) { if (f.Contains(search)) { if (!f.Contains(".doc")) Process.Start(f); review_file_found = true; } } dirsearch(d, search); } } catch (System.Exception excpt) { Console.WriteLine(excpt.Message); } } But it doesn't find the file as well (but seems that search ok- in the sub-directories)

musefan

what string are you passing in as the file to find?

I agree with musefan LOL... but yep, it does work :D

for example; 061_pmr_c0_txhb_cut_rxhb_to_smx.vl.GIF

Yes it works. There are some disadvantages: it will search all before it returns anything. (And the results may be huge). .NET 4.0 will offer some new methods, enumerating while searching, rather than building an array. And a limitation: it only works well as long as a single filter is all you need. Finding all BMP, GIF, PNG, JPEG would need many of those (resulting in a different order), or another tactic. :)

Just open visual studio 2005 / latest add one button (to intiate click event ), one textbox (contains expression you want to search ), and one listbox to show the results add click event on Button1 by double clicking on it and paste following code //replace mine path with your own DirectoryInfo DirInfo = new DirectoryInfo(@"F:\Documents and Settings\Administrator\My Documents\"); FileInfo[] DirFiles = DirInfo.GetFiles(textBox1.Text, SearchOption.AllDirectories); listBox1.Items.Clear(); foreach (FileInfo FileObj in DirFiles) { listBox1.Items.Add(FileObj); } goto top of file and add a namespace >> using System.IO; press F5 and run insert expression to search. click on button. result will be displayed to list box. if this doesnot work the provide me email address i will mail my project to you

Why you didn't use my code ? (The first Comment ?) :confused: No offense , it's just a kind of discussion ... :rose: thank you ...

Yep. I use it in a homebaked app to catalog my picture collection.
