## 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", "3");
                    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", "1");
    
                    //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 ###

### 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!");
