如何在asp.net中调整图像C#的大小-有什么变化吗？

using System;
using System.Drawing;

public class ImageResize
{
    public static void ResizeImage(string sourcePath, string destinationPath, int newWidth, int newHeight)
    {
        // 加载原始图像
        Image originalImage = Image.FromFile(sourcePath);

        // 创建新的位图对象
        Bitmap resizedImage = new Bitmap(newWidth, newHeight);

        // 创建Graphics对象
        using (Graphics graphics = Graphics.FromImage(resizedImage))
        {
            // 绘制原始图像到新的位图上，并调整大小
            graphics.DrawImage(originalImage, 0, 0, newWidth, newHeight);
        }

        // 保存新的位图对象
        resizedImage.Save(destinationPath);

        // 释放资源
        originalImage.Dispose();
        resizedImage.Dispose();
    }
}

string sourcePath = "原始图像路径";
string destinationPath = "调整大小后的图像路径";
int newWidth = 800;
int newHeight = 600;

ImageResize.ResizeImage(sourcePath, destinationPath, newWidth, newHeight);
