使用CDO.Message发送邮件：腾讯企业邮箱有点特别，以上的方法都发送不了，最后找到这个方法可以发送。要引用一个dll，地址：C:\Windows\System32\cdosys.dll
public static void SendMailByCDO()
{
CDO.Message objMail = new CDO.Message();
try
{
objMail.To = "xxx@qq.com";//要发送给哪个邮箱
objMail.From = "xxx@xxx.cn";//你的邮件服务邮箱
objMail.Subject = "这是标题";//邮件主题
objMail.HTMLBody = "这里可以填写html内容";//邮件内容 html
objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpserverport"].Value = 465;//设置端口
objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpserver"].Value = "smtp.exmail.qq.com";
objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/sendemailaddress"].Value = "xxx@xxx.cn";//发送邮件账户
objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpuserreplyemailaddress"].Value = "xxx@xxx.cn";//发送邮件账户
objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpaccountname"].Value = "xxx@xxx.cn";//发送邮件账户
objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/sendusername"].Value = "xxx@xxx.cn";//发送邮件账户
objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/sendpassword"].Value = "xxx";//发送邮件账户密码
objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/sendusing"].Value = 2;
objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpauthenticate"].Value = 1;
objMail.Configuration.Fields["http://schemas.microsoft.com/cdo/configuration/smtpusessl"].Value = "true";//是否使用ssl
//防止中文乱码
objMail.HTMLBodyPart.Charset = "utf-8";
objMail.BodyPart.Charset = "utf-8";
objMail.Configuration.Fields.Update();
objMail.Send();
}
catch (Exception ex) { throw ex; }
finally { }
System.Runtime.InteropServices.Marshal.ReleaseComObject(objMail);
objMail = null;
