一个自己测试通过的发邮件操作

1。通用部分

using System;
using System.Web.Mail;


namespace BusinessServer.DataServer
{
    /**//// <summary>
    /// Mail 的摘要说明。
    /// </summary>
    public class EMail
    {
        public const  string C_strSenderName =  "******";
        public const  string C_strsendpassword =  "******";
        public const  string C_strSmtpServer =  "smtp.***.com";
        public const  string C_strFrom =  "******@***.com";
        public EMail()
        {
            //
            // TODO: 在此处添加构造函数逻辑
            //
        }


        public static bool Send(string strTo, string strFrom, string strSubject, string strMessage)
        {
            try
            {
                MailMessage mailObj = new MailMessage(); 
  
                // 设置email的'from'和'to'的地址 
                mailObj.From = C_strFrom;

                mailObj.Subject = strSubject; 
                mailObj.Body = strMessage; 

  
                // 可选: 使用html格式的Email 
                mailObj.BodyFormat = MailFormat.Html; 
  
                // 可选: 对邮件进行加密 
                // mailObj.BodyEncoding = MailFormat.Base64; 
  
                // 可选: 设置邮件的优先级别为高 
                mailObj.Priority = MailPriority.High; 
   
                mailObj.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");    //basic authentication
                mailObj.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername",C_strSenderName); //set your username here
                mailObj.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", C_strsendpassword);    //set your password here
                // 使用SmtpMail对象来发送邮件。 
                SmtpMail.SmtpServer = C_strSmtpServer;
                SmtpMail.Send(mailObj);
            }
            catch(Exception ee)
            {
                System.Diagnostics.Debug.Write(ee.ToString());
                return false;
            }

2.调用部分
