如何实现模拟web的方式用搜狐邮箱发送邮件？winform的，谢谢了！

private void button2_Click(object sender, EventArgs e)
{
string strHost = ""; //SMTP服务器地址
string strAccount = ""; //SMTP服务帐号
string strPwd = ""; //SMTP服务密码
string strFrom = ""; //发送方邮件地址
String title = "";
String content = "";
SmtpClient _smtpClient = new SmtpClient();
_smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;//指定电子邮件发送方式
_smtpClient.Host = strHost; ;//指定SMTP服务器
_smtpClient.Credentials = new System.Net.NetworkCredential(strAccount, strPwd);//用户名和密码

MailMessage _mailMessage = new MailMessage(new MailAddress(strAccount, strFrom), new MailAddress(to));
//MailMessage _mailMessage = new MailMessage(strAccount, to, title, content);
_mailMessage.Subject = title;//主题
_mailMessage.Body = content;//内容
//_mailMessage.From = new MailAddress(strAccount, strFrom);

_mailMessage.BodyEncoding = System.Text.Encoding.UTF8;//正文编码
_mailMessage.IsBodyHtml = true;//设置为HTML格式

_mailMessage.Priority = MailPriority.High;//优先级

try
{
_smtpClient.Send(_mailMessage);

}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
