您需要使用System.Net.Mail，以及SmtpClient和MailMessage对象，如下所示：

using (MailMessage mail =  new MailMessage("somebody@foo.com", "someoneelse@bar.com"))
{
    //supply host name and mail port
    SmtpClient client = new SmtpClient("YourHostName", 25); 

    mail.Subject = "Hello";
    mail.Body = "Mail body";
    mail.IsBodyHtml = true;

    client.Send(mail);
}

这是我创建的一个包含上述内容的课程：

/// <summary>
/// Wrapper class for the System.Net.Mail objects
/// </summary>
public class SmtpMailMessage : IDisposable
{
    #region declarations

    MailMessage Message;
    SmtpClient SmtpMailClient;

    #endregion

    #region constructors

    /// <summary>
    /// Default constructor for the SmtpMailMessage class
    /// </summary>
    public SmtpMailMessage()
    {
        //initialize the mail message
        Message = new MailMessage();
        Message.Priority = MailPriority.Normal;
        Message.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;            
        Message.From = new MailAddress("testperson@foo.com");           

        //initialize the smtp client
        SmtpMailClient = new SmtpClient();
        SmtpMailClient.DeliveryMethod = SmtpDeliveryMethod.Network;
        SmtpMailClient.Host = "192.168.0.21";
        SmtpMailClient.Port = 25;
    }

    /// <summary>
    /// Parameterized constructor for the SmtpMailMessage class. Allows for override of the default
    /// SMTP host and port number
    /// </summary>
    /// <param name="HostIP">The IP address of the exchange server</param>
    /// <param name="PortNumber">The port number for ingoing and outgoing SMTP messages</param>
    public SmtpMailMessage(string HostIP, int PortNumber) : this()
    {
        //override the smtp host value
        SmtpMailClient.Host = HostIP;

        //override the smtp port value
        SmtpMailClient.Port = PortNumber;
    }
