十、.NET使用本地Outlook邮箱指定邮箱用户名和密码发送邮件

十、.NET使用本地Outlook邮箱指定邮箱用户名和密码发送邮件

1、添加Microsoft.Office.Interop.Outlook引用

2、封装发送邮件方法

using System;
using System.Configuration;
using System.Net.Mail;
 
namespace ServiceMe.Apps.Business.Common.Unity
{
    /// <summary>
    /// 发送邮件帮助类
    /// </summary>
    public class MailHelper
    {
        /// <summary>
        ///  邮箱用户名
        /// </summary>
        private static readonly string mailUserName = ConfigurationManager.AppSettings["MailUserName"];
        /// <summary>
        ///  邮箱密码
        /// </summary>
        private static readonly string mailUserPassword = ConfigurationManager.AppSettings["MailUserPassword"];
        /// <summary>
        /// 邮件服务器
        /// </summary>
        private static readonly string emailServer= ConfigurationManager.AppSettings["EmailServer"];
        /// <summary>
        /// 设置为true允许安全连接本地客户端发送邮件 ,  设置为false不允许允许安全连接本地客户端发送邮件
        /// </summary>
        private static readonly string enableSsl = ConfigurationManager.AppSettings["EnableSsl"];
 
        /// <summary>
        /// 发送EMAIL
        /// </summary>
        /// <param name="sRecipientEmail">收件人地址</param>
        /// <param name="sSubject">主题</param>
        /// <param name="sMessage">内容</param>
        /// <param name="sSendName">发件人名称</param>
        /// <returns>发送是否成功</returns>
        public static bool SendMail(string sRecipientEmail, string sSubject, string sMessage)
        {
            try
            {
                //邮件对象
                MailMessage emailMessage;
 
                //smtp客户端对象
                SmtpClient client;
 
                string sSenderEmail = mailUserName;
                emailMessage = new MailMessage(sSenderEmail, sRecipientEmail, sSubject, sMessage);
                emailMessage.IsBodyHtml = true;
                emailMessage.SubjectEncoding = System.Text.Encoding.Default;
                emailMessage.BodyEncoding = System.Text.Encoding.Default;
                //加入
                emailMessage.Headers.Add("X-Priority", "");
                emailMessage.Headers.Add("X-MSMail-Priority", "Normal");
                emailMessage.Headers.Add("X-Mailer", "Microsoft Outlook Express 6.00.2900.2869");
                emailMessage.Headers.Add("X-MimeOLE", "Produced By Microsoft MimeOLE V6.00.2900.2869");
                emailMessage.Headers.Add("ReturnReceipt", "");
 
                //邮件发送客户端
                client = new SmtpClient();
                //邮件服务器及帐户信息
                client.Host = emailServer;
                //client.Host = "smtp.163.com";
                //client.Port = 465;
                //client.EnableSsl = true;
                System.Net.NetworkCredential Credential = new System.Net.NetworkCredential();
 
                //web.config中读取邮件服务器用户名和密码信息
                Credential.UserName = mailUserName;
                Credential.Password = mailUserPassword;
                client.Credentials = Credential;
                client.EnableSsl =Convert.ToBoolean(enableSsl);
                //发送邮件
                client.Send(emailMessage);
            }
            catch(Exception ex)
            {
                //错误处理待定
                Log4NetHelper.WriteError($"发送邮件错误信息:{ex.Message},\r\n堆栈信息:{ex.StackTrace}");
                return false;
            }
            return true;
        }
    }
}

3、config添加配置文件

<appSettings>
    <!--跨域配置-->
    <add key="cors_allowOrigins" value="*" />
    <add key="cors_allowHeaders" value="*" />
    <add key="cors_allowMethods" value="*" />
    <add key="EmailServer" value="smtp.office365.com"/>
    <add key="EnableSsl" value="true"/>
    <add key="MailUserName" value="xiaogang.tang@medalsoft.com" />
    <add key="MailUserPassword" value="HYqdp776" />
 </appSettings>

4、调用示例

MailHelper.SendMail("xxxx@qq.com", "测试邮件", "请注意，这是一封.NET自动使用OutLook发送的测试邮件!");
