Quick and dirty version:
byte[] fileBytes = File.ReadAllBytes(inputFilename);
StringBuilder sb = new StringBuilder();
foreach(byte b in fileBytes)
{
sb.Append(Convert.ToString(b, 2).PadLeft(8, '0'));
}
File.WriteAllText(outputFilename, sb.ToString());
Well, reading it isn't hard, just use FileStream to read a byte[]. Converting it to text isn't really generally possible or meaningful unless you convert the 1's and 0's to hex. That's easy to do with the BitConverter.ToString(byte[]) overload. You'd generally want to dump 16 or 32 bytes in each line. You could use Encoding.ASCII.GetString() to try to convert the bytes to characters. A sample program that does this:
using System;
using System.IO;
using System.Text;
class Program {
static void Main(string[] args) {
// Read the file into <bits>
var fs = new FileStream(@"c:\temp\test.bin", FileMode.Open);
var len = (int)fs.Length;
var bits = new byte[len];
fs.Read(bits, 0, len);
// Dump 16 bytes per line
for (int ix = 0; ix < len; ix += 16) {
var cnt = Math.Min(16, len - ix);
var line = new byte[cnt];
Array.Copy(bits, ix, line, 0, cnt);
// Write address + hex + ascii
Console.Write("{0:X6} ", ix);
Console.Write(BitConverter.ToString(line));
Console.Write(" ");
// Convert non-ascii characters to .
for (int jx = 0; jx < cnt; ++jx)
if (line[jx] < 0x20 || line[jx] > 0x7f) line[jx] = (byte)'.';
Console.WriteLine(Encoding.ASCII.GetString(line));
}
Console.ReadLine();
}
}
Generally, I don't really see a possible way to do this. I've exhausted all of the options that the earlier comments gave you, and they don't seem to work. You could try this:
`private void button1_Click(object sender, EventArgs e)
{
Stream myStream = null;
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.InitialDirectory = "This PC\\Documents";
openFileDialog1.Filter = "All Files (*.*)|*.*";
openFileDialog1.FilterIndex = 1;
openFileDialog1.RestoreDirectory = true;
openFileDialog1.Title = "Open a file with code";
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
string exeCode = string.Empty;
using (BinaryReader br = new BinaryReader(File.OpenRead(openFileDialog1.FileName))) //Sets a new integer to the BinaryReader
{
br.BaseStream.Seek(0x4D, SeekOrigin.Begin); //The seek is starting from 0x4D
exeCode = Encoding.UTF8.GetString(br.ReadBytes(1000000000)); //Reads as many bytes as it can from the beginning of the .exe file
}
using (BinaryReader br = new BinaryReader(File.OpenRead(openFileDialog1.FileName)))
br.Close(); //Closes the BinaryReader. Without it, opening the file with any other command will result the error "This file is being used by another process".
richTextBox1.Text = exeCode;
}
}`
That's the code for the "Open..." button, but here's the code for the "Save..." button:
` private void button2_Click(object sender, EventArgs e) { SaveFileDialog save = new SaveFileDialog();
save.Filter = "All Files (*.*)|*.*";
save.Title = "Save Your Changes";
save.InitialDirectory = "This PC\\Documents";
save.FilterIndex = 1;
if (save.ShowDialog() == DialogResult.OK)
{
using (BinaryWriter bw = new BinaryWriter(File.OpenWrite(save.FileName))) //Sets a new integer to the BinaryReader
{
bw.BaseStream.Seek(0x4D, SeekOrigin.Begin); //The seek is starting from 0x4D
bw.Write(richTextBox1.Text);
}
}
}`
That's the save button. This works fine, but only shows the '!This cannot be run in DOS-Mode!' - Otherwise, if you can fix this, I don't know what to do.
You can use BinaryReader to read each of the bytes, then use BitConverter.ToString(byte[]) to find out how each is represented in binary.
You can then use this representation and write it to a file.
Use simple FileStream.Read
then print it with Convert.ToString(b, 2)
using (FileStream fs = File.OpenRead(binarySourceFile.Path))
using (BinaryReader reader = new BinaryReader(fs))
{
// Read in all pairs.
while (reader.BaseStream.Position != reader.BaseStream.Length)
{
Item item = new Item();
item.UniqueId = reader.ReadString();
item.StringUnique = reader.ReadString();
result.Add(item);
}
}
return result;
