C# Image to Byte Array and Byte Array to Image Converter Class

First method: Convert Image to byte[] array:

public byte[] imageToByteArray(System.Drawing.Image imageIn)
{
 MemoryStream ms = new MemoryStream();
 imageIn.Save(ms,System.Drawing.Imaging.ImageFormat.Gif);
 return  ms.ToArray();
}

his method uses the System.Drawing.Image.Save method to save the image to a memorystream. Thememorystream can then be used to return a byte array using the ToArray() method in the MemoryStream class.

Second method: Convert byte[] array to Image:

public Image byteArrayToImage(byte[] byteArrayIn)
{
     MemoryStream ms = new MemoryStream(byteArrayIn);
     Image returnImage = Image.FromStream(ms);
     return returnImage;
}
