Convert Image from Byte Array to Image from MS Access using C# [duplicate]

Question

Are there any way to convert Image which is stored in MS Access to byte array using C#? Currently, I have stored my Image into my database which is in byte array format. Now I want to use OleDbReader to read through my image as a byte array, but I dont know how to it.

This is my Insert image into database code:

private byte[] ConvertToDBFormat(IImage InputImage)
    {
        Bitmap BmpImage = new Bitmap(InputImage.Bitmap);
        MemoryStream MyStream = new MemoryStream();
        BmpImage.Save(MyStream, System.Drawing.Imaging.ImageFormat.Jpeg);
        byte[] ImageAsBytes = MyStream.ToArray();
        return ImageAsBytes;
    }

This is my code where I want to read from the database as byte

byte[] buffer = (byte[])reader["FaceImage"];

And what happens with that current code? Are you able to get the byte[] correctly? (Hint: you can construct a MemoryStream from a byte[]...) — Jon Skeet

well yes i can get the byte[] correctly, but I dont really know how to convert it to image format using MemoryStream — raaj5671

Well have you looked at all the members of the Bitmap class, such as the Bitmap(Stream) constructor? — Jon Skeet

simply use it to get the image: Image.FromStream(new MemoryStream(buffer)); — Mehdi Khademloo

You can convert the byte[] to a Bitmap using MemoryStream like this:

private Bitmap ConvertToBitmapFormat(byte[] buffer)
    {
        MemoryStream stream = new MemoryStream(buffer);
        Bitmap image = new Bitmap(stream, false);
        return image;
    }
