In this tutorial, I'll show you how to convert an image to byte array in C#.Net
You can use the MemoryStream to copy data from the Image, then convert to byte array
public byte[] ImageToByteArray(System.Drawing.Image image)
{
using (MemoryStream ms = new MemoryStream())
{
image.Save(ms,image.RawFormat);//Image format JPG, PNG...etc
return ms.ToArray();
}
}
Or you can use the ImageConverter to convert a image to byte array
public static byte[] ConverterImageToByteArray(Image img)
{
ImageConverter image = new ImageConverter();
byte[] data = (byte[])image.ConvertTo(img, typeof(byte[]));
return data;
}
Another way to convert byte array from image
string path = @"C:\Images\csharpcode.jpg"
byte[] images = System.IO.File.ReadAllBytes(HttpContext.Current.Server.MapPath(path));
I hope so you can find the best solution to convert an image to byte array
