resize crop and image

I have a system here to upload an image and crop it using asp.net. When I save the cropped image, It won't resize and stay as the original. How do I resize the picture?

This is my code.

plz help me..

If you are looking for a way to crop and resize the images in your ASP.NET application, the following thread contains useful information that can help:
https://stackoverflow.com/questions/8992619/how-to-crop-and-resize-image-in-one-step-in-net

Alternately, you can try using a specialized imaging SDK such as LEADTOOLS. For example, you can try resize your images to the desired size using the SizeCommand Class:
https://www.leadtools.com/help/leadtools/v20/dh/l/imageprocessing-sizecommand.html
Note that the toolkit also contains functions to crop the image before resizing it.

The following C# ASP.NET server side code shows how you can load your image, automatically crop it and then resize it to any width and height you want:

using (RasterCodecs codecs = new RasterCodecs())
{
MemoryStream MS = ReadImageData();
MS.Seek(0, SeekOrigin.Begin);
// Load an image
using (RasterImage LeadImage = codecs.Load(MS))
{
// Prepare the command
Leadtools.ImageProcessing.Core.AutoCropCommand _autoCrop = new Leadtools.ImageProcessing.Core.AutoCropCommand();
//AutoCrop the image with 20 tolerance.
_autoCrop.Threshold = 20;
_autoCrop.Run(LeadImage);
Leadtools.ImageProcessing.SizeCommand _sizeCommand = new Leadtools.ImageProcessing.SizeCommand();
_sizeCommand.Width = 800;
_sizeCommand.Height = 600;
_sizeCommand.Flags = RasterSizeFlags.Resample;
_sizeCommand.Run(LeadImage);
System.Drawing.Image MainImage = Leadtools.Drawing.RasterImageConverter.ConvertToImage(LeadImage, ConvertToImageOptions.None);
}
}
