使用GMAIL寄信

使用GMAIL寄信

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net.Mail;
using System.Net;

public partial class sendGmail : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
MailMessage msg = new MailMessage();
msg.From = new MailAddress("寄件者帳號@gmail.com", "寄件者顯示名稱"); //
msg.To.Add(new MailAddress("收件人的MAIL帳號@livemail.tw", "收件者顯示名稱")); //可寫迴圈多筆寄送

msg.Subject="主旨";
msg.IsBodyHtml=true;

string str ="<h2>內文1</h2>";
str += "<h3>內文2</h3>";
str += "<h3>543</h3>"; // html上的東西都能收，圖檔要注意路徑，http://網址/資料夾/檔名，也能放超連結

msg.Body = str;
// msg.Attachments //附件
// msg.CC //副本

SmtpClient clinet= new SmtpClient("smtp.gmail.com");

////可用asp.net組態，管理工具設定，下面可以不用自己寫,但要手動去 Web.config 加上 enableSsl = true;
NetworkCredential loginInfo = new NetworkCredential("gmail帳號@gmail.com", "gmail帳號的密碼");

clinet.UseDefaultCredentials = false;
clinet.Credentials = loginInfo;
clinet.EnableSsl = true;

//// clinet.Send("寄件者帳號@gmail.com", "收件者帳號@livemail.tw", "主旨", "內文"); //單筆方式

clinet.Send(msg);
}
}

////Web.config會加上這段，自己加上 enableSsl = "true"

DataAdapter

String strConn = "data source=.;user id=aa;password=aa;initial Catalog=northwind";
using (SqlConnection conn = new SqlConnection(strConn))
{
String strCmd = "Select ProductID,ProductName from Products where categoryID=@categoryID";
using (SqlDataAdapter da = new SqlDataAdapter(strCmd, conn))
{
da.SelectCommand.Parameters.AddWithValue("@categoryID", 1);
DataSet ds = new DataSet();
da.Fill(ds, "dsProducts");

////新增，刪除，修改才要用
//SqlCommandBuilder builder = new SqlCommandBuilder(da);
////新增
//builder.GetInsertCommand();

//DataTable productsTable = ds.Tables["dsProducts"];//修改會用這這行
//DataRow newRow = productsTable.NewRow();
//newRow["ProductName"] = "IP5S";
//newRow["ProductID"] = "1";
//productsTable.Rows.Add(newRow);

////修改
//builder.GetUpdateCommand();
//productsTable.Rows[1]["ProductName"] = "KEVIN";

////刪除
//builder.GetDeleteCommand();
//ds.Tables["dsProducts"].Rows[12].Delete();

////最後更新
//da.Update(ds, "dsProducts"); //最後更新

//查詢用到的迴圈
foreach (DataRow theRow in ds.Tables["dsProducts"].Rows)
{
Response.Write(theRow[0].ToString() + "," + theRow["ProductName"].ToString() + "<br>");
}
