How can I scan an entire drive and delete all files (read-only or not) with multiple specific file extension?

I'm working a feature for a application of mine that on button click it scans the "C:\" 开发者_开发问答drive (and all sub directory's, read-only or not), and deletes all files with specific file extensions. How would I go about doing this? I'm sure a list or a array would be used... but that's about all I know.

Please .Net framework 2.0 ONLY!

Walk the directory tree. The requisite code is described here.

foreach (string filename in Directory.EnumerateFiles(@"C:\", "*.xxx", SearchOption.AllDirectories)
{
    File.Delete(filename);
}

I think the following code would work:

using System.IO;

...


string[] extensions = { "*.apa", "*.dip", "*.ep" }; // whatever extensions you care about
foreach (string ext in extensions)
{
     foreach (string file in Directory.GetFiles(@"c:\", ext, SearchOption.AllDirectories))
     {
          File.SetAttributes(file, FileAttributes.Normal);
          File.Delete(file);
     }
}

foreach (String file in Directory.GetFiles("c:\\","*.iddqd", SearchOption.AllDirectories) )
        File.Delete (file);

try this:

 DirectoryInfo directoryInfo = new DirectoryInfo(@"directory path");
        foreach (var f in directoryInfo.GetFiles("*.*", SearchOption.AllDirectories))
        {
            f.Delete();
        }
