How do I get the hash of current .exe?

Question

[SOLVED]: I copied the file and ran the hasher on that copy.

I need my app to find the EXE\'s current MD5. I can get the MD5 of any file. However, n

Since I've tried these answers and found that none of them change every edit to the exe, or change at all, I found something that actually does work.

I did not edit any code here, all of this was from the referred page below.

Reference: http://www.vcskicks.com/self-hashing.php

internal static class ExecutingHash
{
    public static string GetExecutingFileHash()
    {
        return MD5(GetSelfBytes());
    }

    private static string MD5(byte[] input)
    {
        return MD5(ASCIIEncoding.ASCII.GetString(input));
    }

    private static string MD5(string input)
    {
        MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();

        byte[] originalBytes = ASCIIEncoding.Default.GetBytes(input);
        byte[] encodedBytes = md5.ComputeHash(originalBytes);

        return BitConverter.ToString(encodedBytes).Replace("-", "");
    }

    private static byte[] GetSelfBytes()
    {
        string path = Application.ExecutablePath;

        FileStream running = File.OpenRead(path);

        byte[] exeBytes = new byte[running.Length];
        running.Read(exeBytes, 0, exeBytes.Length);

        running.Close();

        return exeBytes;
    }
}

Every test seems to output properly. I'd recommend to anyone seeing this to use this class or make something of it.
