Image Object in C#

To convert a Bitmap image into a byte array in C#, you can use the following code:

public byte[] ImageToByteArray(Bitmap image)
{
    using (var stream = new MemoryStream())
    {
        image.Save(stream, ImageFormat.Png);
        return stream.ToArray();
    }
}

To create a Bitmap from a byte array of pixel data in C#, you can use the following code:

public Bitmap ByteArrayToImage(byte[] byteArray)
{
    using (var stream = new MemoryStream(byteArray))
    {
        return new Bitmap(stream);
    }
}

To compare two images using byte arrays in C#, you can use the following code:

public bool CompareImages(byte[] byteArray1, byte[] byteArray2)
{
    if (byteArray1.Length != byteArray2.Length)
    {
        return false;
    }

    for (int i = 0; i < byteArray1.Length; i++)
    {
        if (byteArray1[i] != byteArray2[i])
        {
            return false;
        }
    }

    return true;
}

Note that in the above code, the CompareImages method compares the two byte arrays directly. This is a very basic form of comparison and may not be suitable for more complex image comparison scenarios.

Load image in C#:
