How would you write code using a loop to read in the individual files, 1 at a time, from a directory and process them?

I am developing a C# application using VS2010 and .Net Framework 4.0

How would you write code using a loop to read in the individual files with a file name extension of "ard.out",
1 file at a time from a directory (for example: C:\BankABC\).

Then assign these *.ard.out file names to a variable X, so that the files could be read individually by "File.ReadAllBytes(X)" and then additional statements process these files.

byte[] imgBits = File.ReadAllBytes(X);

Here's a general approach, using GetFiles() to get a list of files and then loop through the list to load to a byte array:

//get a list of files in the directory
//GetFiles SearchOption can be set to look at subfolders.  Here I'm just looking at the current folder
//sourceDir would be "C:\BankABC\" in your case
string[] files = Directory.GetFiles(sourceDir, "*.out", SearchOption.TopDirectoryOnly);
foreach(string file in files) 
{
     string fileName = Path.GetFileName(file);
      byte[] imgBits = System.IO.File.ReadAllBytes(fileName);
     //Do some stuff
}

Why am I pointing to two different directory paths in the following code?
The filenames are the same.

My correct path is defined by TARGET_DIR_IN

However, "File.ReadAllBytes(fileName)" defines the path as \\m\USERS\z\My Documents\Visual Studio 2010\Projects\W\bin\Debug\20160824.ard.out'.

------------------
const string TARGET_DIR_IN = @"\\v\na\ctrls\dev\W\data\Test\";

string[] files = Directory.GetFiles(TARGET_DIR_IN, "*.out", SearchOption.TopDirectoryOnly);
            foreach (string file in files)
            {
                string fileName = Path.GetFileName(file);
                byte[] imgBits = File.ReadAllBytes(fileName);

I'm not sure I understand your question.  Are you saying that GetFiles() is not getting the files in TARGET_DIR_IN?
