[Solved] Extract numbers out of a textbox [closed]

Question

This is possible. You’ll actually need to convert 000001111100000111111100000011 or 000111000111000111000111000111 which will be treated as string to a byte array byte[]. To do this, we’ll use Convert.ToByte(object value, IFormatProvider provider)

string input = "BINARY GOES HERE";
int numOfBytes = input.Length / 8; //Get binary length and divide it by 8
byte[] bytes = new byte[numOfBytes]; //Limit the array
for (int i = 0; i < numOfBytes; ++i)
{
     bytes[i] = Convert.ToByte(input.Substring(8 * i, 8), 2); //Get every EIGHT numbers and convert to a specific byte index. This is how binary is converted :)
}

This will declare a new string input and then encode it to a byte array (byte[]). We’ll actually need this as a byte[] to be able to use it as a Stream and then insert it into our PictureBox. To do this, we’ll use MemoryStream

MemoryStream FromBytes = new MemoryStream(bytes); //Create a new stream with a buffer (bytes)

Finally, we can simply use this stream to create our Image file and set the file to our PictureBox

pictureBox1.Image = Image.FromStream(FromBytes); //Set the image of pictureBox1 from our stream

Example

private Image Decode(string binary)
{
    string input = binary;
    int numOfBytes = input.Length / 8;
    byte[] bytes = new byte[numOfBytes];
    for (int i = 0; i < numOfBytes; ++i)
    {
        bytes[i] = Convert.ToByte(input.Substring(8 * i, 8), 2);
    }
    MemoryStream FromBinary = new MemoryStream(bytes);
    return Image.FromStream(FromBinary);
}

By using this, you can whenever call, for example Decode(000001111100000111111100000011) and it will convert it to an image for you. Then, you may use this code to set the Image property of a PictureBox

pictureBox1.Image = Decode("000001111100000111111100000011");

IMPORTANT NOTICE: You may receive ArgumentException was unhandled: Parameter is not valid. this might happen due to an invalid Binary code.
