.Net Core Send Email

1、安装nuget包mailkit，引用命名空间。

using mailkit.net.smtp;
using mimekit;

注意：引用mailkit对应最新版本

2、定义收发地址和标题

mimemessage message = new mimemessage();
mailboxaddress from = new mailboxaddress("admin","[e-mail]");
message.from.add(from);
mailboxaddress to = new mailboxaddress("user", "[e-mail]");
message.to.add(to);
message.subject = "this is email subject";

注意：admin,user分别对应发送接收邮箱前缀

3、编写内容

bodybuilder bodybuilder = new bodybuilder();
bodybuilder.htmlbody = "<h1>hello world!</h1>";
bodybuilder.textbody = "hello world!";
message.body = bodybuilder.tomessagebody();

注意：也可以自定义模板，插入图片等等。

4、连接smtp服务器发送邮件

smtpclient client = new smtpclient();
client.connect("smtp_address_here", port_here, true);  //例如：smtp.exmail.qq.com，465
client.authenticate("[e-mail]", "password")； //发送邮件的账户密码
client.send(message);
client.disconnect(true);
client.dispose();
