如何嵌入的图像流MAILMESSAGE到 [英] How to embed an Image Stream to MailMessage

问题描述

我有一些困难嵌入从Properties.Resources的图像MAILMESSAGE一，目前的图像不会在我收到的电子邮件显示。

我已经成功地嵌入从目录位置的图像，但会preFER如果图像从内存/应用程序来了。

下面是我在做什么的简化版本。

 位图B =新位图（Properties.Resources.companyLogo）;
 MemoryStream的标志=新的MemoryStream（）;
 b.Save（标志，ImageFormat.Jpeg）; MAILMESSAGE NEWEMAIL = MAILMESSAGE新（从，到）;
 newEmail.Subject =主体;
 newEmail.IsBodyHtml = TRUE; LinkedResource footerImg =新LinkedResource（标志，图像/ JPEG）;
 footerImg.ContentId =CompanyLogo的;
 AlternateView英尺= AlternateView.CreateAlternateViewFromString（机身+＆LT; P＆GT;＆LT; IMG SRC = CID：CompanyLogo的/＆GT;＆LT; / P＆gt;中，空，text / html的）; foot.LinkedResources.Add（footerImg）; newEmail.AlternateViews.Add（足）; SmtpClient服务器=新SmtpClient（主机，端口）;
 server.Send（NEWEMAIL）;
 

解决方案

好吧，我已经解决了这个问题。

而不是使用位图保存方法我转换的位图的byte []，给内存流的字节[]

没有工作：

  b.Save（标志，ImageFormat.Jpeg）;
 

没有工作：

 位图B =新位图（Properties.Resources.companyLogo）;
ImageConverter IC =新ImageConverter（）;
字节] BA =（字节[]）ic.ConvertTo（B的typeof（字节[]））;
MemoryStream的标志=新的MemoryStream（BA）;
 

我觉得它有什么做的Bitmap.Save方法，在MSDN LIB它提到，流必须具有0偏移量。

I'm having some difficulty embedding an image from the Properties.Resources to a MailMessage, currently the image does not show in the email i receive.

I have successfully embedded the image from a directory location but would prefer if the image came from memory/the application.

Here is a simplified version of what I am doing.

 Bitmap b = new Bitmap(Properties.Resources.companyLogo);
 MemoryStream logo = new MemoryStream();
 b.Save(logo, ImageFormat.Jpeg);



 MailMessage newEmail = new MailMessage(from, to);
 newEmail.Subject = subject;
 newEmail.IsBodyHtml = true;

 LinkedResource footerImg = new LinkedResource(logo, "image/jpeg");
 footerImg.ContentId = "companyLogo";
 AlternateView foot= AlternateView.CreateAlternateViewFromString(body + "<p> <img src=cid:companyLogo /> </p>", null, "text/html");

 foot.LinkedResources.Add(footerImg);

 newEmail.AlternateViews.Add(foot);             

 SmtpClient server = new SmtpClient(host, port);
 server.Send(newEmail);

解决方案

Ok i have solved the problem.

Instead of using the BitMap save method I converted the BitMap to Byte[] and gave the memory stream the Byte[]

Did not work :

 b.Save(logo, ImageFormat.Jpeg);

Did Work:

Bitmap b = new Bitmap(Properties.Resources.companyLogo);
ImageConverter ic = new ImageConverter();
Byte [] ba = (Byte[]) ic.ConvertTo(b,typeof(Byte[]));
MemoryStream logo = new MemoryStream(ba);

I think it has something to do with the Bitmap.Save method, in the MSDN lib it mentioned that the stream has to have an offset of 0.
