首先要定义一个邮件信息的基类，如下所示：
复制代码 代码如下:
///
/// base message class used for emails
///
public class Message
{
#region Constructor
///
/// Constructor
///
public Message()
{
}
#endregion
#region Properties
///
/// Whom the message is to
///
public virtual string To { get; set; }
///
/// The subject of the email
///
public virtual string Subject { get; set; }
///
/// Whom the message is from
///
public virtual string From { get; set; }
///
/// Body of the text
///
public virtual string Body { get; set; }
#endregion
}
然后定义一个邮件的发送类，使用Netmail的方式发送邮件，发送邮件时采用了.net中自带的线程池，
通过多线程来实现异步的发送，代码如下：
复制代码 代码如下:
///
/// Utility for sending an email
///
public class EmailSender : Message
{
#region Constructors
///
/// Default Constructor
///
public EmailSender()
{
Attachments = new List();
EmbeddedResources = new List
Priority = MailPriority.Normal;
}
#endregion
#region Public Functions
///
/// Sends an email
///
/// The body of the message
public void SendMail(string Message)
{
Body = Message;
SendMail();
}
///
/// Sends a piece of mail asynchronous
///
/// Message to be sent
public void SendMailAsync(string Message)
{
Body = Message;
ThreadPool.QueueUserWorkItem(delegate { SendMail(); });
}
///
/// Sends an email
///
public void SendMail()
{
using (System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage())
{
char[] Splitter = { ',', ';' };
string[] AddressCollection = To.Split(Splitter);
for (int x = 0; x < AddressCollection.Length; ++x)
{
if(!string.IsNullOrEmpty(AddressCollection[x].Trim()))
message.To.Add(AddressCollection[x]);
}
if (!string.IsNullOrEmpty(CC))
{
AddressCollection = CC.Split(Splitter);
for (int x = 0; x < AddressCollection.Length; ++x)
{
if (!string.IsNullOrEmpty(AddressCollection[x].Trim()))
message.CC.Add(AddressCollection[x]);
}
}
if (!string.IsNullOrEmpty(Bcc))
{
AddressCollection = Bcc.Split(Splitter);
for (int x = 0; x < AddressCollection.Length; ++x)
{
if (!string.IsNullOrEmpty(AddressCollection[x].Trim()))
message.Bcc.Add(AddressCollection[x]);
}
}
message.Subject = Subject;
message.From = new System.Net.Mail.MailAddress((From));
AlternateView BodyView = AlternateView.CreateAlternateViewFromString(Body, null, MediaTypeNames.Text.Html);
foreach (linkedResource Resource in EmbeddedResources)
{
BodyView.linkedResources.Add(Resource);
}
message.AlternateViews.Add(BodyView);
//message.Body = Body;
message.Priority = Priority;
message.SubjectEncoding = System.Text.Encoding.GetEncoding("ISO-8859-1");
message.BodyEncoding = System.Text.Encoding.GetEncoding("ISO-8859-1");
message.IsBodyHtml = true;
foreach (Attachment TempAttachment in Attachments)
{
message.Attachments.Add(TempAttachment);
}
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient(Server, Port);
if (!string.IsNullOrEmpty(UserName) && !string.IsNullOrEmpty(Password))
{
smtp.Credentials = new System.Net.NetworkCredential(UserName, Password);
}
if (UseSSL)
smtp.EnableSsl = true;
else
smtp.EnableSsl = false;
smtp.Send(message);
}
}
///
/// Sends a piece of mail asynchronous
///
public void SendMailAsync()
{
ThreadPool.QueueUserWorkItem(delegate { SendMail(); });
}
#endregion
#region Properties
///
/// Any attachments that are included with this
/// message.
///
public List Attachments { get; set; }
///
/// Any attachment (usually images) that need to be embedded in the message
///
public List
///
/// The priority of this message
///
public MailPriority Priority { get; set; }
///
/// Server Location
///
public string Server { get; set; }
///
/// User Name for the server
///
public string UserName { get; set; }
///
/// Password for the server
///
public string Password { get; set; }

public int Port { get; set; }

#endregion
