Answer 1

那么 Image.HorizontalResolution 和 Image.VerticalResolution 呢？像这样：

System.Drawing.Image image = System.Drawing.Image.FromFile("TestImage.bmp");
var dpiX = image.HorizontalResolution;
var dpiY = image.VerticalResolution;

属性注释表明这是每英寸像素，而不是每英寸点。不确定是否有区别... - Nyerguds

Answer 2

答案已经在这篇文章中阐述，它的代码来源于这里：

using System;
using System.Drawing;

namespace BitmapDpi
{
    class Program
    {
        static void Main(string[] args)
        {
            Bitmap bmp = new Bitmap("winter.jpg");
            Console.WriteLine("Image resolution: " + bmp.HorizontalResolution + "DPI");
        }
    }
}
