Hi, Priya Use following method(it takes three argument and return resized image): using System.Drawing;using System.Drawing.Imaging;using System.Drawing.Drawing2D; public Image ScaleImage(Image image, int maxWidth, int maxHeight){ var ratioX = (double)maxWidth / image.Width; var ratioY = (double)maxHeight / image.Height; var ratio = Math.Min(ratioX, ratioY); var newWidth = (int)(image.Width * ratio); var newHeight = (int)(image.Height * ratio); var newImage = new Bitmap(newWidth, newHeight); Graphics.FromImage(newImage).DrawImage(image, 0, 0, newWidth, newHeight); return newImage;}If you have image byte array then use followin converter methods:public byte[] ImageToByteArray(System.Drawing.Image m_imageIn){ MemoryStream oMemoryStream = new MemoryStream(); // ImageFormat could be other formats like bmp,gif,icon,png etc. m_imageIn.Save(oMemoryStream, System.Drawing.Imaging.ImageFormat.Jpeg); return oMemoryStream.ToArray();} public System.Drawing.Image ByteArrayToImage(byte[] m_byteArrayIn){ MemoryStream oMemoryStream = new MemoryStream(m_byteArrayIn);System.Drawing.Image oImage = System.Drawing.Image.FromStream(oMemoryStream); return oImage;}
