c#发送邮件.net1.1和.net2.0中的两个方法

.net1.1
using System.Web.Mail;
使用：
SendSMTPEMail("100.100.100.100", "", "xxxx", "", "webtest", TextBox1.Text, null, null);
方法体：
public void SendSMTPEMail(string strSmtpServer, string strFrom, string strFromPass, string strto, string strSubject, string strBody, string bcc, string cc)
        {
            System.Web.Mail.MailMessage mail = new System.Web.Mail.MailMessage();
            mail.BodyFormat = MailFormat.Html;
            mail.From = strFrom;
            mail.To = strto;    //多个收件人之间用分号分割
            mail.Bcc = bcc;
            mail.Cc = cc;
            mail.Subject = "mail test!!!";
            mail.Body = TextBox1.Text;
            mail.Fields.Add("", "1");
            mail.Fields.Add("", strFrom);
            mail.Fields.Add("", strFromPass);

            System.Web.Mail.MailAttachment attachment = new System.Web.Mail.MailAttachment("c:\\log.log");
            mail.Attachments.Add(attachment);
            SmtpMail.SmtpServer = strSmtpServer;
            SmtpMail.Send(mail);
        }
.net2.0
using System.Net.Mail;
使用：
SendSMTPEMail("100.100.100.100", "", "xxxx", "", "webtest", TextBox1.Text, null, null);
方法体：
 public void SendSMTPEMail(string strSmtpServer, string strFrom, string strFromPass, string strto, string strSubject, string strBody)
        {
            System.Net.Mail.SmtpClient client = new SmtpClient(strSmtpServer);
            client.UseDefaultCredentials = false;
            client.Credentials = new System.Net.NetworkCredential(strFrom, strFromPass);
            client.DeliveryMethod = SmtpDeliveryMethod.Network;

            System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(strFrom, strto, strSubject, strBody);
            System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment("c:\\log.log");
            message.Attachments.Add(attachment);
            message.BodyEncoding = System.Text.Encoding.UTF8;
            message.IsBodyHtml = true;
            client.Send(message);
        }
