数据库如何加载和显示图像.in asp.net .. [英] How database to load and display images .in asp.net..

问题描述

我想将图像保存到数据库，并且图像可以加载到用户创建的文件夹，然后我们必须选择图像并发送到邮件。

我使用以下代码，< br $> b $ b

 受保护  void  Upload_Click（ object  sender，EventArgs e）
 {
  String  s =（ String ）会话[  temp]; 
  if （FileUpload1.HasFile）
 {
  //  < span class =code-comment> string fileName = Path.GetFileName（FileUpload1.PostedFile.FileName）;  
  //   FileUpload1.PostedFile.SaveAs（Server.MapPath（〜/+ s +\\）+ fileName）;  
 
  string  fileName = Path.GetFileName（FileUpload1.PostedFile.FileName）; 
 path = Server.MapPath（ 〜/ + s +   \\）+ fileName; 
 FileUpload1.SaveAs（path）; 
 Response.Redirect（Request.Url.AbsoluteUri）; insert imges 
  //   Session [PATH] = path;  
 
} 
 
 
 
 
 受保护  void  Send_Click（ object  sender，EventArgs e）
 {
  String  sndps =（ String ）会话[  pswd]; 
  //   String s =（String）Session [PATH];  
 字符串 s =（字符串）会话[  temp]; 
 字符串 em =（字符串）会话[   email]; 
  //   TextBox1.Text = em;  
 MailMessage msg =  new  MailMessage（）; 
  string  ActivationUrl =  string  .Empty; 
  string  emailid =  string  .Empty; 
 SmtpClient smtp =  new  SmtpClient（）; 
  string  emailId = em; 
 msg.From =  new  MailAddress（  [e-mail]）; 
 msg.To.Add（em）; 
 msg.Subject =   Conformation mail; 
 msg.Body =  您的登录密码为： + sndps; 
 msg.IsBodyHtml =  true ; 
  //   string [] files = Directory.GetFiles（path）;  
  / *   foreach（文件中的字符串文件）
 {
 Console.WriteLine（file）; 
} * /  
 
  //   msg.Attachments.Add （文件）;  
  //  新附件（文件））;  
  ///   / if（FileUpload1.HasFile）
   ///   / {
   //   msg.Attachments.Add（new Attachment（files。））;  
  ///   /} 
  
 
 
 smtp.Host =   smtp.gmail.com; 
 smtp.EnableSsl =  true ; 
 NetworkCredential NetworkCred =  new  NetworkCredential（  a @ gmail.com，  r）; 
 smtp.UseDefaultCredentials =  true ; 
 smtp.Credentials = NetworkCred; 
 smtp.Port =  587 ; 
 smtp.Send（msg）; 
 Response.Write（  msg snd ........）; 
 
 
  //   Session [temp1] = Usernametxt.Text;  
  //  会话[temp2] = emailtxt.Text;  
  //   Response.Redirect（http：// localhost：62874 / MapExtractor / MsgSendPage.aspx）;

I want to save images to the database and that images can be loaded to user created folder,then we have to select the image and send to the mail.
I use the following code,

protected void Upload_Click(object sender, EventArgs e)
   {
       String s = (String)Session["temp"];
       if (FileUpload1.HasFile)
       {
           // string fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
           // FileUpload1.PostedFile.SaveAs(Server.MapPath("~/" + s + "\\") + fileName);

           string fileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
           path = Server.MapPath("~/" + s + "\\") + fileName;
           FileUpload1.SaveAs(path);                                         
           Response.Redirect(Request.Url.AbsoluteUri);                                insert imges
           // Session["PATH"] = path;

       }




protected void Send_Click(object sender, EventArgs e)
    {
        String sndps=(String)Session["pswd"];
        // String s = (String)Session["PATH"];
        String s = (String)Session["temp"];
        String em = (String)Session["email"];
        //TextBox1.Text = em;
        MailMessage msg = new MailMessage();
        string ActivationUrl = string.Empty;
        string emailid = string.Empty;
        SmtpClient smtp = new SmtpClient();
        string emailId = em;
        msg.From = new MailAddress("[e-mail]");
        msg.To.Add(em);
        msg.Subject = "Conformation mail";
        msg.Body ="Your Login Password is:"+sndps;
        msg.IsBodyHtml = true;
       // string[] files = Directory.GetFiles(path);
        /*foreach (string file in files)
        {
            Console.WriteLine(file);                           
        }*/

        // msg.Attachments.Add( files);
        //new Attachment(files));
        //// if (FileUpload1.HasFile)
        //// {
        // msg.Attachments.Add(new Attachment(files.));
        //// }



        smtp.Host = "smtp.gmail.com";
        smtp.EnableSsl = true;
        NetworkCredential NetworkCred = new NetworkCredential("[e-mail]", "r");
        smtp.UseDefaultCredentials = true;
        smtp.Credentials = NetworkCred;
        smtp.Port = 587;
        smtp.Send(msg);
        Response.Write("msg snd........");


        //Session["temp1"] = Usernametxt.Text;
        //Session["temp2"] = emailtxt.Text;
        //Response.Redirect("http://localhost:62874/MapExtractor/MsgSendPage.aspx");
