How to change the image size from original size in carousel Item?

//Initialize the data table
 
DataTable dt = new DataTable();
 
dt.Columns.Add("col1", typeof(byte[]));
 
//Set Image
 
Image img = Image.FromFile(@"../../Images/10812.jpg");
 
Image img1 = Image.FromFile(@"../../Images/Bird.jpg");
 
Image img2 = Image.FromFile(@"../../Images/10811.jpg");
 
Image img3 = Image.FromFile(@"../../Images/Bird.jpg");
 
DataRow dr = dt.NewRow();
 
DataRow dr1 = dt.NewRow();
 
DataRow dr2 = dt.NewRow();
 
DataRow dr3 = dt.NewRow();
 
//Add image to data table
 
dr["col1"] = imageToByteArray(img);
 
dr1["col1"] = imageToByteArray(img1);
 
dr2["col1"] = imageToByteArray(img2);
 
dr3["col1"] = imageToByteArray(img3);
 
dt.Rows.Add(dr);
 
dt.Rows.Add(dr1);
 
dt.Rows.Add(dr2);
 
dt.Rows.Add(dr3);
 
//Image into carousel
 
SetImagesForCarousel();
 
public byte[] imageToByteArray(System.Drawing.Image imageIn)
{
 
MemoryStream ms = new MemoryStream();
 
imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
 
return ms.ToArray();
 
}
 
‘To Add Carousel dynamically
 
object value = null;
 
private void SetImagesForCarousel()
{
 
foreach (DataRow drow in dt.Rows)
{
 
value = drow["col1"];
 
if (value.ToString().Length > 0)
{
 
byte[] imagenbuffer = (byte[])value;
 
MemoryStream ms = new MemoryStream(imagenbuffer);
 
CarouselImage carouselImage = new CarouselImage();
 
 
carouselImage.ItemImage = Image.FromStream(ms);
 
//To change the dimension of the image.
 
carouselImage.ItemImage = resizeImage(carouselImage.ItemImage, new Size(800, 600));
 
carousel1.ImageListCollection.Add(carouselImage);
 
}
}
 
this.carousel1.ImageSlides = true;
 
this.carousel1.RotateAlways = false;
 
this.carousel1.TransitionSpeed = 1f;
 
this.carousel1.ShowImagePreview = true;
 
carousel1.UseOriginalImageinPreview = true;
 
}
 
public static Image resizeImage(Image imgToResize, Size size)
{
 
return (Image)(new Bitmap(imgToResize, size));
 
}
