将图像添加到System.Net.Mail消息 [英] Adding Image to System.Net.Mail Message
问题描述
我的解决方案中有一些存储在Resources.resx文件中的图像。我想在我的电子邮件中使用这些图片。我已将图像加载到变量中：
I have some images stored in the Resources.resx file in my solution. I would like to use these images in my email. I have loaded the image into a variable:
Bitmap myImage = new Bitmap(Resources.Image);
现在我想把它放在我用来创建HTML的AlternateView字符串的HTML中电子邮件。只需要一些帮助。
and now I want to put it in the HTML in the AlternateView string I am using to create the HTML email. Just need some help.
这是HTML字符串（部分）：
Here is the HTML string(partial):
body += "</HEAD><BODY><DIV style='height:100%; width:700px;'><div style='height:70px; width:700px; background-color:red;'><img src='" + myImage + "' width='104' height='27' alt='img' style='margin: 20px 0px 0px 20px;'/></div>
非常感谢任何帮助谢谢！
Any help would be greatly appreciated Thanks!
编辑：这是整个代码块。我想我已接近它，只是缺乏经验阻碍这里:)我尝试将它转换为像我所说的那样让我更远的字节。仍然没有渲染图片。这里有些东西我做得不对。非常感谢你们所有人帮助大家！这是代码（图片所需的HTML在字符串体的3行=代码中）：
Here is the entire Code block. I think I am close to getting it, just inexperience getting in the way here :) I tried converting it into a Byte like suggested which got me farther. Still not rendering the image. There is something here I am not doing right. Thank you so much for all of you help everyone! Here is the code (the HTML I need for the image is in the 3 line of the string body = code):
if (emailTo != null)
{
Bitmap myImage = new Bitmap(Resources.comcastHeader);
ImageConverter ic = new ImageConverter();
Byte[] ba = (Byte[])ic.ConvertTo(myImage, typeof(Byte[]));
MemoryStream image1 = new MemoryStream(ba);
LinkedResource headerImage = new LinkedResource(image1, "image/jpeg");
headerImage.ContentId = "companyLogo";
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.To.Add("" + emailTo + "");
message.Subject = "" + customer + " Your order is being processed...";
message.From = new System.Net.Mail.MailAddress("noreply@stormcopper.com");
string body = "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">";
body += "<HTML><HEAD><META http-equiv=Content-Type content=\"text/html; charset=iso-8859-1\">";
body += "</HEAD><BODY><DIV style='height:100%; width:700px;'><div style='height:70px; width:700px; background-color:red;'><img src=\"cid:companyLogo\" width='104' height='27' alt='img' style='margin: 20px 0px 0px 20px;'/></div><P>Hello " + customer + ",</P><P>Thank you for shopping at <a href='" + store + "'>" + store + "</A>.

ContentType mimeType = new System.Net.Mime.ContentType("text/html");
AlternateView alternate = AlternateView.CreateAlternateViewFromString(body, mimeType);
message.AlternateViews.Add(alternate);
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient("########");
smtp.Send(message);
}
推荐答案
你需要将它们作为CID /链接资源添加到电子邮件中。
you need to add them in the email message as CID's/linked resources.
这里是我之前使用过的一些代码很好的代码。我希望这能给你一些指导：
here is some code I have used before which works nicely. I hope this gives you some guidance:
创建一个AlternativeView：
Create an AlternativeView:
AlternateView av = AlternateView.CreateAlternateViewFromString(body, null, isHTML ? System.Net.Mime.MediaTypeNames.Text.Html : System.Net.Mime.MediaTypeNames.Text.Plain)
创建链接资源：
LinkedResource logo = new LinkedResource("SomeRandomValue", System.Net.Mime.MediaTypeNames.Image.Jpeg);
logo.ContentId = currentLinkedResource.Key;
logo.ContentType = new System.Net.Mime.ContentType("image/jpg");
//将其添加到备用视图
// add it to the alternative view
av.LinkedResources.Add(logo);
//最后，在邮件中添加备用视图：
// finally, add the alternative view to the message:
msg.AlternativeViews.Add(av);
这里有一些文档可以帮助您了解AlternativeView和LinkedResources是什么以及它是如何工作的：
here is some documentation to help you with what the AlternativeView and LinkedResources are and how it works:
http://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage.alternateviews（v = vs.110）.aspx
http：// msdn .microsoft.com / zh-CN / library / system.net.mail.linkedresource（v = vs.110）.aspx
http://msdn.microsoft.com/en-us/library/ms144669（v = vs.110）.aspx <在HTML本身中，您需要执行以下操作：
http://msdn.microsoft.com/en-us/library/system.net.mail.mailmessage.alternateviews(v=vs.110).aspx http://msdn.microsoft.com/en-us/library/system.net.mail.linkedresource(v=vs.110).aspx http://msdn.microsoft.com/en-us/library/ms144669(v=vs.110).aspx
in the HTML itself, you need to do something like the following: < img style = \width：157px;身高：60px; \alt = \blah blah \title = \我的头衔在这里\src = \cid：{0} \/>;
注意CID后跟字符串格式{0} - 然后我用它来替换它随机价值。
notice the CID followed by a string format {0} - I then use this to replace it with a random value.

返回并评论海报评论......这是海报的工作解决方案：
To go back and comment on the posters comments... here is the working solution for the poster:
string body = "blah blah blah... body goes here with the image tag: <img src=\"cid:companyLogo\" width="104" height="27" />";
byte[] reader = File.ReadAllBytes("E:\\TestImage.jpg");
MemoryStream image1 = new MemoryStream(reader);
AlternateView av = AlternateView.CreateAlternateViewFromString(body, null, System.Net.Mime.MediaTypeNames.Text.Html);
LinkedResource headerImage = new LinkedResource(image1, System.Net.Mime.MediaTypeNames.Image.Jpeg);
headerImage.ContentId = "companyLogo";
headerImage.ContentType = new ContentType("image/jpg");
av.LinkedResources.Add(headerImage);
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.AlternateViews.Add(av);
message.To.Add(emailTo);
message.Subject = " Your order is being processed...";
message.From = new System.Net.Mail.MailAddress("xxx@example.com");
ContentType mimeType = new System.Net.Mime.ContentType("text/html");
AlternateView alternate = AlternateView.CreateAlternateViewFromString(body, mimeType);
message.AlternateViews.Add(alternate);
//然后发送消息！
