使用c#给outlook添加任务、发送邮件

2008-12-23 18:33 483 查看
c#在使用outlook提供的一些API时,需要将outlook相关的com引用到项目中。 具体方法就是用vs打开工程后,在工程上添加引用,在com选项卡上,选择Microsoft Outlook 12.0 Object Library,如果安装的不是outlook2007,则对应com的版本不一样。注意下面描述的方法是在命令行模式或者winform模式下的,不是web模式下的。 在web模式下使用的方法稍有不同,不在此处讨论。
给outlook添加任务,代码如下:
/// <summary>
/// 给outlook添加一个新的任务
/// </summary>
/// <param name="subject">新任务标题</param>
/// <param name="body">新任务正文</param>
/// <param name="dueDate">新任务到期时间</param>
/// <param name="importance">新任务优先级</param>
public static void AddNewTask(string subject, string body, DateTime dueDate, OlImportance importance)
{
try
{
Application outLookApp = new Application();
TaskItem newTask = (TaskItem)outLookApp.CreateItem(OlItemType.olTaskItem);
newTask.Body = body;
newTask.Subject = subject;
newTask.Importance = importance;
newTask.DueDate = dueDate;
newTask.Save();
}
catch(System.Exception e)
{
throw e;
}
}
最简单的发送邮件
下面是一个最简单的发送邮件的例子,在该例子中,只能给一个邮箱地址发邮件,而且还不能够添加附件。代码如下:

/// <summary>
/// 一个最简单的发送邮件的例子。同步方式。只支持发送到一个地址,而且没有附件。
/// </summary>
/// <param name="server">smtp服务器地址</param>
/// <param name="from">发送者邮箱</param>
/// <param name="to">接收者邮箱</param>
/// <param name="subject">主题</param>
/// <param name="body">正文</param>
/// <param name="isHtml">正文是否以html形式展现</param>
public static void SimpleSeedMail(string server, string from, string to, string subject, string body, bool isHtml)
{
try
{
MailMessage message = new MailMessage(from, to, subject, body);
message.IsBodyHtml = isHtml;
SmtpClient client = new SmtpClient(server);
client.Credentials = new NetworkCredential("发送者邮箱用户名(即@前面的东东)","发送者邮箱密码");
client.Send(message);
}
catch (System.Exception e)
{
throw e;
}
}
向多人发邮件,并支持发送多个附件
代码如下:
/// <summary>
/// 支持向多人发邮件,并支持多个附件的一个发送邮件的例子。
/// </summary>
/// <param name="server">smtp服务器地址</param>
/// <param name="from">发送者邮箱</param>
/// <param name="to">接收者邮箱,多个接收者以;隔开</param>
/// <param name="subject">邮件主题</param>
/// <param name="body">邮件正文</param>
/// <param name="mailAttach">附件</param>
/// <param name="isHtml">邮件正文是否需要以html的方式展现</param>
public static void MultiSendEmail(string server, string from, string to, string subject, string body, ArrayList mailAttach, bool isHtml)
{
MailMessage eMail = new MailMessage();
SmtpClient eClient = new SmtpClient(server);
eClient.Credentials = new NetworkCredential("发送者邮箱用户名(即@前面的东东)", "发送者邮箱密码");

eMail.Subject = subject;
eMail.SubjectEncoding = Encoding.UTF8;

eMail.Body = body;
eMail.BodyEncoding = Encoding.UTF8;

eMail.From = new MailAddress(from);

string[] arrMailAddr;

try
{
#region 添加多个收件人
eMail.To.Clear();
if (!string.IsNullOrEmpty(to))
{
arrMailAddr = to.Split(';');
foreach (string strTo in arrMailAddr)
{
if (!string.IsNullOrEmpty(strTo))
{
eMail.To.Add(strTo);
}
}
}
#endregion
#region 添加多个附件
eMail.Attachments.Clear();
if (mailAttach != null)
{
for (int i = 0; i < mailAttach.Count; i++)
{
if (!string.IsNullOrEmpty(mailAttach[i].ToString()))
{
eMail.Attachments.Add(new System.Net.Mail.Attachment(mailAttach[i].ToString()));
}
}
}
#endregion
#region 发送邮件
eClient.Send(eMail);
#endregion
}
catch (System.Exception e)
{
throw e;
}

}//end of method
异步发送邮件的一个例子。以163的smtp服务器为例。
代码如下:
using System;
using System.Net;
using System.Net.Mail;
using System.Net.Mime;
using System.Threading;
using System.ComponentModel;
namespace Examples.SmptExamples.Async
{
public class SimpleAsynchronousExample
{
static bool mailSent = false;

private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e)
{
// Get the unique identifier for this asynchronous operation.
String token = (string)e.UserState;

if (e.Cancelled)
{
Console.WriteLine("[{0}] Send canceled.", token);
}
if (e.Error != null)
{
Console.WriteLine("[{0}] {1}", token, e.Error.ToString());
}
else
{
Console.WriteLine("Message sent.");
}
mailSent = true;
}

public static void Main(string[] args)
{
SmtpClient client = new SmtpClient("smtp.163.com");
client.Credentials = client.Credentials = new NetworkCredential("发送者邮箱用户名", "发送者邮箱密码");

MailAddress from = new MailAddress("softwarezxj@163.com");
MailAddress to = new MailAddress("lastBeachhead@gmail.com");
MailMessage message = new MailMessage(from, to);
message.Body = "这是一封测试异步发送邮件的邮件 ";
message.BodyEncoding = System.Text.Encoding.UTF8;
message.Subject = "测试异步发邮件";
message.SubjectEncoding = System.Text.Encoding.UTF8;

// 设置回调函数
client.SendCompleted += new SendCompletedEventHandler(SendCompletedCallback);
// SendAsync方法的第二个参数可以是任何对象,这里使用一个字符串标识本次发送
//传入的该对象可以在邮件发送结束触发的回调函数中访问到。
string userState = "test message1";
client.SendAsync(message, userState);
Console.WriteLine("Sending message... press c to cancel mail. Press any other key to exit.");
string answer = Console.ReadLine();

if (answer.StartsWith("c") && mailSent == false)
{
client.SendAsyncCancel();
}
//清理工作
message.Dispose();
Console.WriteLine("Goodbye.");
Console.ReadLine();
}
}
}
