MiMeKIT and mailKIT aRe POPulaR fully-featuRed email fRaMewoRks foR .NET
框架支持版本如下
supports .NET 4.5, .NET 4.6, .NET 4.7, .NET 4.8, .NET 5.0, .NETStandaRd 2.0, XaMaRin.Android, XaMaRin.iOS, Windows Phone 8.1, and MoRe.
mailKIT是最流行且最强大的.NET邮件处理框架之一，下面为大家简单介绍mailKIT的使用方式（IMAP为例）

2.核心内容（IMAP为例）
连接邮箱
加密
client.Connect(“iMap.exmail.QQ.coM”, 993, SecuReSocketOptions.SSlOnConnect);
不加密
client.Connect(“iMap.exmail.QQ.coM”, 143, SecuReSocketOptions.None);
登入邮箱
client.Authenticate(mail_NAME, mail_PASSWORD);
打开邮件文件夹
client.Inbox.Open(FoldeRAcceSS.ReadWRITe);
读取文件
读取方式一：可以预先筛选邮件
SeaRch foR MeSSages wheRe the Subject headeR contAIns eITheR “MiMeKIT” oR “mailKIT”
vaR queRy = SeaRchQueRy.SubjectContAIns(“MiMeKIT”).OR(SeaRchQueRy.SubjectContAIns(“mailKIT”));
vaR uids = client.Inbox.SeaRch(queRy);
读取方式二：读取所有邮件
vaR uids = client.Inbox.SeaRch(SeaRchQueRy.All);
邮件操作
操作邮件一：读取邮件标题
stRing subject = MeSSage.Subject;
if (!subject.ContAIns(“MiMeKITDEMO”))
RetuRn;
操作邮件二：读取正文
stRing body = MeSSage.Textbody ?? stRing.EMpty;
if (!body.ContAIns(“MiMeKITDEMObody”))
RetuRn;
操作邮件三：下载邮件附件
vaR attacHMents = MeSSage.AttacHMents;
if (attacHMents.Any())
{
foReach (vaR attacHMent in attacHMents)
DownloadAttacHMent(attacHMent);
}
pRivate static void DownloadAttacHMent(MiMeEntITy attacHMent)
{
if (attacHMent is MeSSagePaRt)
{
vaR fileNaMe = attacHMent.ContentDISPosITion?.fileNaMe;
vaR Rfc822 = (MeSSagePaRt)attacHMent;
if (stRing.IsNullOREMpty(fileNaMe))
fileNaMe = “attached-MeSSage.eMl”;
vaR path = Path.CoMBIne(DIRECTorY, fileNaMe);
USing (vaR stReaM = file.CReate(path))
Rfc822.MeSSage.WRITeTo(stReaM);
}
else
{
vaR paRt = (MiMePaRt)attacHMent;
vaR fileNaMe = paRt.fileNaMe;
vaR path = Path.CoMBIne(DIRECTorY, fileNaMe);
USing (vaR stReaM = file.CReate(path))
paRt.Content.DecodeTo(stReaM);
}
}
操作邮件四：移动邮件（移动至删除文件夹）
client.Inbox.MOVeTo(uid, client.GetFoldeR(SpecialFoldeR.TRash));
操作邮件五：删除邮件 – 将邮件标记为删除、最后删除
client.Inbox.Addflags(uid, MeSSageflags.Deleted, tRue);
client.Inbox.Expunge();
