How to convert image to binary and get result in text box

I need to convert image to binary and get result in text box .

Image found in path D:/person.jpg

i using the following function :




public bool[] imageToBinaryArray(System.Drawing.Image imageIn)
{
MemoryStream ms = new MemoryStream();
bool[] arr = new bool[50000000];
int i =0;
imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
BitArray bitarray = new BitArray(ms.ToArray());
foreach (bool item in bitarray)
{
arr[i] = item;
i++;
}
return arr;
}

How to receive the value returned from function imageToBinaryArray in textbox1 ?

Firstly, please don't post unformatted code snippets as they are hard to read.

csharp Code:

public bool[] imageToBinaryArray(System.Drawing.Image imageIn)
        {
            MemoryStream ms = new MemoryStream();
            bool[] arr = new bool[50000000];
            int i =0;
            imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
            BitArray bitarray = new BitArray(ms.ToArray());
            foreach (bool  item in bitarray)
            {
                arr[i] = item;
                i++;
            }
            return arr;
        }

As for the question, what are you actually expecting to see in the TextBox? Do you want a binary string, i.e. a string of 1 and 0 digits?

yes because i need to get image in binary string 0 and 1

You already know how to get a byte array from an Image so all you need is how to get a binary string from a byte array:

csharp Code:

// No gaps between bytes.
var myBinaryString1 = string.Concat(myByteArray.Select(b => Convert.ToString(b, 2).PadLeft(8, '0')));
 
// One space between each pair of bytes.
var myBinaryString2 = string.Join(" ", myByteArray.Select(b => Convert.ToString(b, 2).PadLeft(8, '0')));

Just be aware that a string requires two bytes per character so, if your Image is large, your string will be very big and may not be practical to display in a TextBox or even store in memory.
