用网页显示图片的方法

方法一、显示原图

using System;

namespace DtCms.Web.Tools
{
    public partial class img : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string gurl = "/UpLoadFiles/20110117/2011011719440778.jpg";
            Response.ContentType = "image/jpg";
            Response.Clear();
            Response.WriteFile(gurl);
        }

    }
}

方法二、二进制显示原图

using System;
using System.IO;

namespace DtCms.Web.Tools
{
    public partial class httpimg : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string filePath = "图片路径";
            Response.ContentType = "image/jpg";
            FileStream imageStr = new FileStream(filePath, FileMode.Open);
            byte[] imageData = new byte[imageStr.Length];
            imageStr.Read(imageData, 0, (int)imageStr.Length);
            Response.OutputStream.Write(imageData, 0, (int)imageStr.Length);  

        }
    }
}
