How to resize an Image C#

Question

As Size, Width and Height are Get() properties of System.Drawing.Image;
How can I resize an Image object

Answer 1

Why not use the System.Drawing.Image.GetThumbnailImage method?

public Image GetThumbnailImage(
    int thumbWidth, 
    int thumbHeight, 
    Image.GetThumbnailImageAbort callback, 
    IntPtr callbackData)

Example:

Image originalImage = System.Drawing.Image.FromStream(inputStream, true, true);
Image resizedImage = originalImage.GetThumbnailImage(newWidth, (newWidth * originalImage.Height) / originalWidth, null, IntPtr.Zero);
resizedImage.Save(imagePath, ImageFormat.Png);
