通过C#发送自定义的html格式邮件

通过C#发送邮件，可以根据自己的需求更改。

这个是个配置文件的类，可以用，也可以改，也可以不用。

using System;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;namespace WaterCubeCheck
{[Serializable]public class dataStruct//配置结构{public stringmingcheng1 = "服务器1",mingcheng2 = "服务器2",lianjie1 = "Data Source=localhost;Initial Catalog=test;User ID=sa;Password=123456",lianjie2 = "Data Source=localhost;Initial Catalog=test;User ID=sa;Password=123456",Toaddress = "test@163.com,test1@163.com",Fromaddress = "test@139.com",Fromaddressname = "测试",MailSub = "测试",FromMailPassword = "123456",SmtpServer = "smtp.139.com";public bool issendingEmail = false;public int starttime = 9;public int endtime = 19;public int sendtime = 60;public dataStruct(){mingcheng1 = "服务器1";mingcheng2 = "服务器2";lianjie1 = "Data Source=localhost;Initial Catalog=test;User ID=sa;Password=123456";lianjie2 = "Data Source=localhost;Initial Catalog=test;User ID=sa;Password=123456";Toaddress = "test@163.com";Fromaddress = "test1@163.com";Fromaddressname = "Server";MailSub = "测试";FromMailPassword = "123456";SmtpServer = "smtp.163.com";issendingEmail = false;starttime = 9;endtime = 19;sendtime = 60;}}[Serializable]public class MailBodyCon{public stringmachStr = "";public stringpattenStr = "";public int count = 0;public MailBodyCon(){machStr = "";pattenStr = "";count = 0;}}public static class appConfig{public static dataStruct conf = new dataStruct();public static MailBodyCon body = new MailBodyCon();/// <summary>/// 保存到配置文件/// </summary>/// <returns>返回是否成功</returns>public static bool savetofile(){try{string path = AppDomain.CurrentDomain.BaseDirectory;Stream fs = new FileStream(path + "app.cfg", FileMode.OpenOrCreate);BinaryFormatter formatter = new BinaryFormatter();formatter.Serialize(fs, conf);fs.Close();}catch{}return true;}/// <summary>/// 读取配置文件/// </summary>/// <returns>返回是否成功</returns>public static bool readfromfile(){try{string path = AppDomain.CurrentDomain.BaseDirectory;Stream fs = new FileStream(path + "app.cfg", FileMode.OpenOrCreate);BinaryFormatter formatter = new BinaryFormatter();conf = (dataStruct)formatter.Deserialize(fs);fs.Close();}catch{}return true;}}
}

这个是邮件内容的拼接以及发送类。

using System;
using System.Collections.Generic;
using System.Text;
using System.Net.Mail;
using System.Windows.Forms;
using System.Data;
using System.IO;namespace WaterCubeCheck
{public class MailClass{/// <summary>/// 发送邮件/// </summary>/// <param name="data">邮件内容</param>public void SendStrMail(string data){try{System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();if (appConfig.conf.Toaddress.IndexOf(',') > -1){string[] mails = appConfig.conf.Toaddress.Split(',');//多个收信地址用逗号隔开for (int counti = 0; counti < mails.Length; counti++){if (mails[counti].Trim() != ""){msg.To.Add(mails[counti]);}}}else{msg.To.Add(appConfig.conf.Toaddress);//添加单一收信地址}msg.To.Add(appConfig.conf.Fromaddress);msg.From = new System.Net.Mail.MailAddress(appConfig.conf.Fromaddress, appConfig.conf.Fromaddressname, System.Text.Encoding.UTF8);/* 上面3个参数分别是发件人地址(可以随便写)，发件人姓名，编码*/string sub = appConfig.conf.MailSub;//邮件标题 if (appConfig.body.count == 0){msg.Subject = appConfig.conf.MailSub;}else{msg.Subject = data;}msg.SubjectEncoding = System.Text.Encoding.UTF8;//邮件标题编码//long tol = GateCount + HandCount;msg.Body = data;msg.BodyEncoding = System.Text.Encoding.UTF8;//邮件内容编码 msg.IsBodyHtml = true;//是否是HTML邮件 msg.Priority = MailPriority.High;SmtpClient client = new SmtpClient();client.Credentials = new System.Net.NetworkCredential(appConfig.conf.Fromaddress, appConfig.conf.FromMailPassword);//在zj.com注册的邮箱和密码 client.Host = appConfig.conf.SmtpServer;//邮件发送服务器，上面对应的是该服务器上的发信帐号和密码object userState = msg;try{client.SendAsync(msg, userState);//开始发送}catch (System.Net.Mail.SmtpException ex){MessageBox.Show(ex.Message.ToString());}}catch (Exception ee){MessageBox.Show(ee.Message.ToString());}}}//发送带表格邮件public class SendMail{public static MailClass Mail=new MailClass();public static string LargeMailBody="";//初始化多表格邮件内容//单一表格邮件内容public static void SendMsg(DataTable data){string MailBody = "<p style=\"font-size: 10pt\">以下内容为系统自动发送，请勿直接回复，谢谢。</p><table cellspacing=\"1\" cellpadding=\"3\" border=\"0\" bgcolor=\"000000\" style=\"font-size: 10pt;line-height: 15px;\">";MailBody += "<div align=\"center\">";MailBody += "<tr>";for (int hcol = 0;

调用的时候用这个方法

        private void button1_Click(object sender, EventArgs e){t1 = databind(qishishijian.Value, jieshushijian.Value);t2 = databind1(qishishijian.Value, jieshushijian.Value);SendMail.LargeMailBody = "";try{SendMail.SendLargeMsg(t1, "测试内容1);SendMail.SendLargeMsg(t2, "测试内容2");SendMail.Mail.SendStrMail("<p style=\"font-size: 10pt\">以下内容为系统自动发送，请勿直接回复，谢谢。</p>" + SendMail.LargeMailBody);}catch { MessageBox.Show("没有可以发送的内容！"); }}
