以下代码可完成邮件发送:
using System.Net.Mail;
using System.Net.Mime;
using System.Net.Cache;
using System.Net;

MailMessage message = new MailMessage();
message.From = new MailAddress("@163.com");
message.To.Add("qq.com");
message.To.Add("qq.com");
message.Subject = "";
message.Body = "";

Attachment data = new Attachment(Page.MapPath(""));

message.Attachments.Add(data);

SmtpClient smtp = new SmtpClient("smtp.163.com");

smtp.Credentials = new NetworkCredential("", "");

smtp.Send(message);

Public Function SendMail()
Try
Dim mail As New MailMessage
mail.From = "<" + FromAddr + ">" + FromName
mail.To = toAddress
mail.Cc = CcAddress
mail.Bcc = BccAddress
mail.Subject = Subject
mail.Body = CreateBody(Body, New String() {strCallerBasyoID})

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", "true")
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1")
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", UserName)
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", PassWord)
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", Integer.Parse(smtpport))

System.Web.Mail.SmtpMail.SmtpServer = SearverIp
System.Web.Mail.SmtpMail.Send(mail)

Catch ex As Exception
HCLogger.WriteLog(HCLogger.LogLevel.ERR, "")
Dim strFormBase As HCFormBase = HCFormBase.GetForm("HCErrorMessageForm")

If Not strFormBase Is Nothing Then
strFormBase.CallingNotice(Nothing, Nothing, errorMessage)
End If
End Try
End Function
#End Region

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", UserName)
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", PassWord)

this.Response.Write("<script>alert('Sent Successfully.');</script>");
this.tbmail.Text = "";
}
catch(Exception ex)
{
HttpContext.Current.Response.Write(ex.Message);
}
}
