Getting file by file located in a folder

Question

I got a folder that contains millions and millions of files (under windows server2012), and, using Directory.GetFiles needs a lot of times to get all these files,

I am just wondering if there is any c# method that can return file by file instead of getting all these files at once,

(just like an SQLDataReader and using while (reader.Read()) to get line by line within DB)

@Souregi it is not really a big task. Use your favorite search engine and type 'EnumerateFiles' and you will find all the examples you like — Steve, Nov 29 '16 at 11:47
@Souregi use the same code you used to enumerate the results of `GetFiles` — Panagiotis Kanavos, Nov 29 '16 at 11:50

DirectoryInfo di = new DirectoryInfo(yourPath);

foreach (var fi in di.EnumerateFiles())
{
     Console.WriteLine(fi.Name);
}

You can use DirectoryInfo.EnumerateFiles

Returns an enumerable collection of file information in the current directory.

Return Value Type: System.Collections.Generic.IEnumerable<FileInfo>

You can try something like this

foreach(var file in Directory.EnumerateFiles(path)) {
    //access your files
}

_"try something like this"_ - try explaining why. – CodeCaster Nov 29 '16 at 11:51
People can try a lot. An answer should not contain "try". It should contain reasoning why it works – Thomas Weller Nov 29 '16 at 11:51
