How to put image in a picture box from a byte[] in C#


I've a byte array which contains an image binary data in bitmap format. How do I display it using the PictureBox control in C#?

I went thru a couple of posts listed below but not sure if I need to convert the byte array into something else before sending it to a picturebox. I'd appreciate your help. Thanks!

How to put image in a picture box from Bitmap Load Picturebox Image From Memory?


Solution

  • This function converts byte array into Bitmap which can be use to set the Image Property of the picturebox.

    public static Bitmap ByteToImage(byte[] blob)
    {
        MemoryStream mStream = new MemoryStream();
        byte[] pData = blob;
        mStream.Write(pData, 0, Convert.ToInt32(pData.Length));
        Bitmap bm = new Bitmap(mStream, false);
        mStream.Dispose();
        return bm;
    }
    

    Sample usage:

    pictureBox.Image = ByteToImage(byteArr); // byteArr holds byte array value
