如何在 C# 中发起会议之类的特殊邮件

从C#中调用Outlook中的API,可以发起会议之类的特殊邮件。方法如下:

创建项目后,为它添加.NET引用:“Microsoft.Office.Interop.Outlook“的引用,即可调用,需要注意的是,在添加的时候,注意一下Office版本号。

在调用其API发起会议的过程中,遇到了一个问题:

创建完一个约会条目后,找了很久没找到如何为这一约会指定“发件人”,后来一想,Window CF 中,查找人员信息有个OutlookSession的东东,

那这Outlook会不会有同样的方式呢,经过测试,还真的找到方法,原来,它的API指定的发件人是和你机上运行的Outlook的帐户设置直接相关的。

通过 ApplicationClass.Session.Accounts即可找到您设置的帐户集合,需要特别特别注意的是,在这里,取某个人员时,集合的索引是从1开始,而不是

从0开始。 找到相关的帐户后,可以通过 AppointmentItem.SendUsingAccount 属性来指定约会的发件人。

下面是测试的代码,在WIN2003+OFFICE12下运行通过,成功创建会议:

以下为引用的内容:

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Office.Interop.Outlook;
/**/////////////////////

       {
            try
            {
                ApplicationClass oApp = new Microsoft.Office.Interop.Outlook.ApplicationClass();
                //会议是约会的一种
                AppointmentItem oItem = (AppointmentItem)oApp.CreateItem(OlItemType.olAppointmentItem);
                oItem.MeetingStatus = OlMeetingStatus.olMeeting;
                oItem.Subject = "主题";
                oItem.Body = "内容";
                oItem.Location = "地点";
                //开始时间 
                oItem.Start = DateTime.Now.AddDays(1);
                //结束时间
                oItem.End = DateTime.Now.AddDays(2);
                //提醒设置
                oItem.ReminderSet = true;
                oItem.ReminderMinutesBeforeStart = 5;
                //是否全天事件
                oItem.AllDayEvent = false;
                oItem.BusyStatus = OlBusyStatus.olBusy;               
                //索引从1开始,而不是从0
                //发件人的帐号信息
                oItem.SendUsingAccount = oApp.Session.Accounts[2];              
                //添加必选人
                Recipient force = oItem.Recipients.Add("mailuser2@mailserver.com");
                force.Type = (int)OlMeetingRecipientType.olRequired;
                //添加可选人
                Recipient opt = oItem.Recipients.Add("mailuser3@p.mailserver.com");
                opt.Type = (int)OlMeetingRecipientType.olOptional;
                //添加会议发起者
                Recipient sender = oItem.Recipients.Add("mailuser1@mailserver.com");
                sender.Type = (int)OlMeetingRecipientType.olOrganizer;                
                oItem.Recipients.ResolveAll();
                //oItem.SaveAs("d:/TEST.MSG", OlSaveAsType.olMSG);
                oItem.Send();
                //MailItem mItem = (MailItem)oApp.CreateItem(OlItemType.olMailItem);
                //Recipient rTo = mItem.Recipients.Add("****");
                //rTo.Type = (int)OlMailRecipientType.olTo;
                //Recipient rCC=mItem.Recipients.Add("****");
                //rCC.Type = (int)OlMailRecipientType.olCC;
                //Recipient rBC = mItem.Recipients.Add("****");
                //rBC.Type = (int)OlMailRecipientType.olBCC;

               Console.WriteLine("OK");
            }
            catch (System.Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

            Console.ReadLine();
