Reading a directory file by file

Question

Is it possible to read files from a directory one file after another?

I look for something like:

while (File file = Directory.GetFile(path)) {
    //
    // Do something with file
    //
}

[UPDATE]

I already knew about GetFiles() but I'm looking for a function that return one file at a time.

EnumerateFiles() is .Net4.x, would be nice to have, but I'm using .Net2.0. Sorry, that I didn't mention.

why can you not use `GetFiles()`? – default May 15 '12 at 06:42 — default, May 15 '12 at 06:42

You can enumerate over the file names:

foreach(string fileName in Directory.EnumerateFiles(path)) {

    // Do something with fileName - using `FileInfo` or `File`

}

string[] arFiles = Directory.GetFiles(@"C:\");

foreach (var sFilename in arfiles)
{
    // Open file named sFilename for reading, do whatever
    using (StreamReader sr = File.OpenText(sFilename )) 
    {
        string s = "";
        while ((s = sr.ReadLine()) != null) 
        {
            Console.WriteLine(s);
        }
    }
}

foreach (var file in Directory.EnumerateFiles(path))
{
    var currFileText = File.ReadAllText(file);
}

What about Directory.GetFiles(path) method?

foreach(String fileName in Directory.GetFiles(path))
{
    FileInfo file = new FileInfo(fileName);
}

Try with this...

 foreach (var filePath in Directory.GetFiles(path))
            {
                var text = File.ReadAllText(filePath);
                // Further processing
            }
