推荐答案

这是最常见的问题，谷歌创建pdf文件c＃获取数千个现有答案。

This is the most frequently asked question, google "create pdf file c#" for thousands of existing answers.

这是一组可以使用的PDF库参考： http://csharp-source.net/open-source/pdf-libraries 。



这可能是最常用的库： iTextSharp，一个.NET PDF库SourceForge.net [ ^ ]。



现在，关于邮件附件。这是一项非常令人困惑的工作。事实上，没有任何附加。电子邮件是带有可选部件的纯文本数据块。每个部分都可以拥有自己的内容类型和内容配置。请参阅：

MailMessage类（System.Net.Mail） [ ^ ]，

MailMessage.Attachments Property（System.Net.Mail） [ ^ ]，

AttachmentBase .ContentType属性（System.Net.Mail） [ ^ ]，

Attachment.ContentDisposition Property（System.Net.Mail） [< a href =https://msdn.microsoft.com/en-us/library/system.net.mail.attachment.contentdisposition%28v=vs.110%29.aspx\"target =_ blanktitle =新窗口> ^ ]，

ContentDisposition类（System.Net.Mime） [ ^ ]。



内容类型得到维护，由IANA标准化，在此处：

媒体类型，

媒体类型（ Text ）。



如您所见，您需要application / pdf。该内容的数据（与大多数其他情况一样）应以base64格式表示（ Base64 - 维基百科，免费百科全书 [ ^ ]）。至于 ContentDisposition ，它显示了邮件消息查看器如何显示该部件。它可以在单一流程中呈现，主要内容是商品下载，因此您有以下选项：

DispositionTypeNames.Inline Field（System.Net.Mime） [ ^ ]，
DispositionTypeNames.Attachment字段（System.Net.Mime） [ ^ ]。



使用PDF，你当然需要姓氏值 ContextDisposition ， System.Net.Mime.DispositionTypeNames.Attachment 。



最后，s结束邮件。在.NET FCL中，支持SMTP： SmtpClient类（System.Net.Mail） [ ^ ]。



对于其他客户端协议，您可以轻松找到第三方解决方案，但SMTP通常就够了。

This is a set of references to PDF libraries you can use: http://csharp-source.net/open-source/pdf-libraries.

This is probably the most used library: iTextSharp, a .NET PDF library | SourceForge.net[^].

Now, about mail "attachment". This is a very confusing work. In fact, nothing is "attached". E-mail is a pure-text block of data with optional "parts". Each part can have it's own content type and content disposition. Please see:
MailMessage Class (System.Net.Mail)[^],
MailMessage.Attachments Property (System.Net.Mail)[^],
AttachmentBase.ContentType Property (System.Net.Mail)[^],
Attachment.ContentDisposition Property (System.Net.Mail)[^],
ContentDisposition Class (System.Net.Mime)[^].

Content types are maintained and standardized by IANA, here:
Media Types,
Media Types (Text).

As you can see, you need "application/pdf". The data for this content (as with most other cases), should be represented in base64 form (Base64 - Wikipedia, the free encyclopedia[^]). As to ContentDisposition, it shows the mail message viewer how to display the part. It can be rendered in the single flow with main content of offer downloading, hence you have these options:
DispositionTypeNames.Inline Field (System.Net.Mime)[^],
DispositionTypeNames.Attachment Field (System.Net.Mime)[^].

With PDF, you certainly need the last name value for ContextDisposition, System.Net.Mime.DispositionTypeNames.Attachment.

Finally, sending mail. In .NET FCL, SMTP is supported: SmtpClient Class (System.Net.Mail)[^].

For other client protocols, you can easily find 3rd-party solutions, but SMTP is usually enough.
