如何在ASP.NET中加载图像服务器端？

using System.Drawing;

// 从文件加载图像
Image image = Image.FromFile("path/to/image.jpg");

// 从流加载图像
using (FileStream fs = new FileStream("path/to/image.jpg", FileMode.Open))
{
    Image image = Image.FromStream(fs);
}

using System.Web;

HttpResponse response = HttpContext.Current.Response;
response.ContentType = "image/jpeg";

// 从文件加载图像
byte[] imageData = File.ReadAllBytes("path/to/image.jpg");
response.BinaryWrite(imageData);

// 从流加载图像
using (FileStream fs = new FileStream("path/to/image.jpg", FileMode.Open))
{
    byte[] buffer = new byte[1024];
    int bytesRead;
    while ((bytesRead = fs.Read(buffer, 0, buffer.Length)) > 0)
    {
        response.BinaryWrite(buffer, 0, bytesRead);
    }
}

using System.Drawing;
using System.IO;
using System.Web;

public class ImageHandler : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "image/jpeg";

        // 从文件加载图像
        Image image = Image.FromFile("path/to/image.jpg");
        image.Save(context.Response.OutputStream, ImageFormat.Jpeg);

        // 从流加载图像
        using (FileStream fs = new FileStream("path/to/image.jpg", FileMode.Open))
        {
            byte[] buffer = new byte[1024];
            int bytesRead;
            while ((bytesRead = fs.Read(buffer, 0, buffer.Length)) > 0)
            {
                context.Response.OutputStream.Write(buffer, 0, bytesRead);
            }
        }
    }

    public bool IsReusable
    {
        get { return false; }
    }
}
