{
    byte[] bytes = File.ReadAllBytes(op.FileName);
    for (int i = 0; i < bytes.Length; i++)
    {
        bytes[i] += (byte)numericUpDown1.Value;
        bytes[i]  += (byte)(numericUpDown2.Value);
        bytes[i] -= (byte)numericUpDown3.Value;
    }
    SaveFileDialog sv = new SaveFileDialog();
    sv.Filter = Path.GetExtension(op.FileName).ToString().Replace(".", "").ToUpper() + "|*" + Path.GetExtension(op.FileName);
   if( sv.ShowDialog()== DialogResult .OK )
       File.WriteAllBytes(sv.FileName, bytes);

The compact framework does not include the whole of .NET - as I'm sure you know.

Unfortunately, File.ReadAllBytes and File.WriteAllBytes are two of the casualties.

They are simple to replace though:

C#

public static byte[] ReadAllBytes(string path)
    {
    byte[] data;
    using (FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.Read))
        {
        int offset = 0;
        int count = (int) fs.Length;
        data = new byte[count];
        while (count > 0)
            {
            int bytesRead = fs.Read(data, offset, count);
            offset += bytesRead;
            count -= bytesRead;
            }
        }
    return data;
    }

WriteAllBytes is the same process in reverse: I'll leave it to you!

not leave me because i know this code from other site
but i don't know the reverse
anyway thanks for help"

You are kidding, right?

It is kinda simple:

C#

public static void WriteAllBytes(string path, byte[] data)
    {
    using (FileStream fs = new FileStream(path, FileMode.Create, FileAccess.Write, FileShare.None))
        {
        fs.Write(data, 0, data.Length);
        }
    }

Even a beginner should be able to work that one out... :laugh:
