Convert byte[] into image using ASP.Net

[RasMus]

I was able to convert my images to Byte[] but not able to get it convet it into the Byte[] to image, i have number of images stored in my database and they are in the JPG format. Is there any best way to convert these pictures from Byte[] to Image. I've got the image in the var Image:

byte[] Image;

I have tried some code for this in ASP.net but when i execute this code it gives me list of error messages.

Regards

To access to the image you need to create a MemoryStream from the byte array and then call Image.FromStream,

Convert Image to byte[] array:

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

or you may use this sample code

Image MemoSt;
DataPhoto = new Byte[File.ContentLength];
MemoSt=Image.FromStream(DataPhoto);

And to Convert byte[] array to Image:

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

If you have not properly coded your image flushing then data is not being recognized as an image format. and to check that you may try using a System.Drawing.Bitmap method instead of an Image, to see if that will work you just need to pass 'data' into the constructor (Dim b As New Bitmap(ms) ),Even if doing this changes doesn't work, you should need to post your code that converts from a file to bytes to see if the problem lies there. and this problem might be related to the improper flushing of your images.

While searching on the internet i read in one blog that you need to convert a byte array to back to an image so that it can be displayed in a PictureBox control, you can use the following function:

public Image ByteArrayToImage(byte[] data)
{
MemoryStream bipimag = new MemoryStream(data);
Image imag = new Bitmap(bipimag);
return imag;
}

And to access that you can use this as follows:

pictureBox2.Image = ByteArrayToImage(data);
