邮件也疯狂之Outlook约会邮件

　　工作中经常用邮件来进行沟通，对我来说，经常使用outlook来收发邮件。用outlook发邮件大家一定也不陌生，但outlook中有一种“约会邮件”大家一定用的不多，这类邮件一般是领导安排任务或召开重大会议时的一种通知方式，因为它有提醒功能。

新建约会邮件

(新建约会邮件)

时间、地点、人物

(录入信息，注意有一个提醒设置)

简单介绍完了，下面就来看看如何用代码实现，废话不多说直接上代码，因为也不是我写的。(当时在项目中为了实现这个功能可花了N长时间)

Code
publicstruct AppointMail
{
    publicstring from;     //发件人邮箱
publicstring to;        //收件人邮箱;号分隔的一个串
publicstring fromDisplayName; //发件人姓名
publicstring subject;  //标题
publicstring body;     //正文
publicstring location; //地点
public DateTime sTime;  //开始时间
public DateTime eTime;  //结束时间
}

Code
publicstaticvoid SendAppointMail(AppointMail mail)
    {
        MailMessage msg =new MailMessage();
        MailAddressCollection attendeeList =new MailAddressCollection();

        string[] sendTo = mail.to.Split(';');
        foreach (string temp in sendTo)
        {
            msg.Bcc.Add(temp);
            attendeeList.Add(temp);
        }

        //  Set up the different mime types contained in the message
        System.Net.Mime.ContentType textType =new System.Net.Mime.ContentType("text/plain");
        System.Net.Mime.ContentType HTMLType =new System.Net.Mime.ContentType("text/html");
        System.Net.Mime.ContentType RTFType =new System.Net.Mime.ContentType("text/rtf");
        System.Net.Mime.ContentType calendarType =new System.Net.Mime.ContentType("text/calendar;");
        //Add parameters to the calendar header
        calendarType.Parameters.Add("method", "REQUEST");
        calendarType.Parameters.Add("name", "meeting.ics");
        //calendarType.Parameters.Add("charset", "utf-8");
        //  Create message body parts 

        /*
        //  create the Body in text format

        bodyText = string.Format(bodyText,
        mail.fromDisplayName,
        mail.sTime.ToLongDateString() + " " + mail.sTime.ToLongTimeString(),

        AlternateView textView = AlternateView.CreateAlternateViewFromString(bodyText, textType);
        msg.AlternateViews.Add(textView);*/


        //create the Body in HTML format

        bodyCalendar =string.Format(bodyCalendar,
        mail.sTime.ToUniversalTime().ToString(calDateFormat),
        mail.eTime.ToUniversalTime().ToString(calDateFormat),
        mail.location,
        mail.fromDisplayName,
        mail.from,
        Guid.NewGuid().ToString("B"),
        mail.subject,//summary
        mail.body,//正文
        DateTime.Now.ToUniversalTime().ToString(calDateFormat),
        attendeeList.ToString(),
        mail.body
        );
        AlternateView calendarView = AlternateView.CreateAlternateViewFromString(bodyCalendar, calendarType);
        calendarView.TransferEncoding = TransferEncoding.SevenBit;
        msg.AlternateViews.Add(calendarView);

        //  Adress the message
        msg.From =new MailAddress(mail.from, mail.fromDisplayName);
        msg.IsBodyHtml =true;
        SmtpClient smtpClient =new SmtpClient(ConfigurationManager.AppSettings["mail"]);
        smtpClient.Send(msg);
    }

这个功能有一个小问题，就是无法在邮件正文中设置html样式,虽然设置了IsBodyHtml = true;但可惜还是不行，希望哪位高人能够解决一下~
