Search for files with specific extension

[Merrit]

Hi there,

I'm looking for a pretty easy way to search a folder for all contained
files with a specific extension and show the filenames in a listbox or
sth similar.

How can do that without using an OpenFileDialog?

Cheers,
Merrit

You can try to PInvoke FindFirstFile and FindNextFile to achieve this.

[DllImport("kernel32", CharSet=CharSet.Unicode)]
public static extern IntPtr FindFirstFile(string lpFileName, out
WIN32_FIND_DATA lpFindFileData);

[DllImport("kernel32", CharSet=CharSet.Unicode)]
public static extern bool FindNextFile(IntPtr hFindFile, out
WIN32_FIND_DATA lpFindFileData);

Hope this helps,
Cheers,
Arun.

System.IO.Directory.GetFiles("somefolder", "*.ext")

Returns an array of strings with the full paths of matching files in the
specified folder.

Thanks a lot Peter. This solution was much easier and worked perfectly well.

System.IO.Directory.GetFiles("somefolder", "*.ext")

And how to get them sorted by Date or by Size ?

thanx.

You'll have to sort them, using what you learned in your programming classes
in college...

LOL! Nevertheless, it could be done without knowing about "Binary sort",
"Bubble sort", "Shell sort" or something

Here is example how to sort files by its size:

private class SizeSorter : IComparer
{
int IComparer.Compare(object a, object b)
{
FileInfo afi = new FileInfo(a as string);
FileInfo bfi = new FileInfo(b as string);
return afi.Length.CompareTo(bfi.Length);
}
}


....

string [] f = Directory.GetFiles("currentdir", "*.*");
ArrayList al = new ArrayList(f);
al.Sort(new SizeSorter());

"al" will contain the sorted files.
