通過C#發送郵件，可以根據自己的需求更改。

這個是個配置文件的類，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//配置結構{public stringmingcheng1 = "服務器1",mingcheng2 = "服務器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 = "測試",MailSub = "測試",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 = "服務器1";mingcheng2 = "服務器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 = "測試";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>/// 讀取配置文件/// </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;}} }

這個是郵件內容的拼接以及發送類。

調用的時候用這個方法

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, "測試內容1);SendMail.SendLargeMsg(t2, "測試內容2");SendMail.Mail.SendStrMail("<p style=\"font-size: 10pt\">以下內容為系統自動發送，請勿直接回復，謝謝。</p>" + SendMail.LargeMailBody);}catch { MessageBox.Show("沒有可以發送的內容！"); }}
