如何将图像发送到asp.net，c＃中的邮件。 [英] how to images are sending to mail in asp.net, c# .

问题描述

早上好，先生，



i我在数据库中以innary格式插入图片。



然后我的问题是如何从数据库获取图像

并将图像发送到邮件，我也想从邮件中下载图像。



i尝试了一些。



string emailid =[e-mail];

MailMessage mm = new MailMessage（） ;

SmtpClient smtp = new SmtpClient（）;

mm.From = new MailAddress（emailid）;

mm.Subject =文件跟踪;

mm.Body =hai;



附件imgAtt =新附件（img.ImageUrl.ToString（））;

//附件imgAtt = new Atta chment（Server.MapPath（+ ViewState [path]。ToString（）+））;

//给它一个内容id，对应于我们在正文中添加的src img标签

imgAtt.ContentId = ViewState [path]。ToString（）;

//将附件添加到电子邮件中

mm .Attachments.Add（imgAtt）;



mm.IsBodyHtml = true;

smtp.Host =smtp.gmail.com;

smtp.EnableSsl = true;

mm.To.Add（新邮件地址（ViewState [EditVendorEmail]。ToString（）））;

System.Net.NetworkCredential NetworkCred = new System.Net.NetworkCredential（）;

NetworkCred.UserName =[e-mail]; //写你的gmail用户名

NetworkCred.Password = abc123; //写密码

smtp.UseDefaultCredentials = true;

smtp.Credentials = NetworkCred;

smtp.Port = 587; //电子邮件的Gmail端口465或587

smtp.Send（mm）;





但我有一些疑问



附件imgAtt =新附件（img.ImageUrl.ToString（））;



在该附件中如何发送图像（我正在从数据库中发送图像）。还可以下载从邮件发送图像。

推荐答案

你必须要把图像保存在一个不起眼的位置，以便可以通过发送邮件中提供的链接在任何网络邮件上查看。

电子邮件中的嵌入图像 - ASP.NET，C＃ [ ^ ]

You must have to save the image on an obscure location, so that it can be viewed on any webmail via link provided in the sent mail.

Avinash是对的，首先您需要将二进制数据保存在图像泡沫中的特定位置，然后您可以将该图像附加到您的电子邮件中。你也可以参考下面的文章：

控制在ASP.NET中显示二进制图像 [ ^ ]

Avinash is right, first you need to save the binary data on a specific location in the foam of a image, then you can attach that image to your email. You can also refer below article:
