    ▪.net SMTP发送Email邮件且可带附件示例       代码如下: public static void sendEmail(string toAddress, string emailbody) { var fromAddress = ConfigurationManager.AppSettings["EmailAddress"]; string fromPassword = ConfigurationManager.AppSettings["EmailPassword"].ToString(); const string sub.........

代码如下:

<!--登录小div-->
<div >
<div >
会员登录
</div>
<table >
<tr>
<td >用户名:</td>
<td><input type="text" id="txtUserName" /></td>
</tr>
<tr>
<td >密码:</td>
<td><input type="password" id="txtPass" /></td>
</tr>
<tr>
<td colspan="2">
<input src="/images/az-login-gold-3d.gif" type="image" id="btnLogin" />
<input src="/images/az-newuser-gold-3d.gif" type="image" id="btnReg" />
</td>
</tr>
</table>
</div>
<div >
<span id="spanUserInfo">
尊敬的<%=serverUserName %>,欢迎你光临!
</span>
</div>

代码如下:

protected string serverUserName;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Model.Users user = Session["currUser"] as Model.Users;
if (user != null)
{
serverUserName = user.Name;
}
}
}

代码如下:

public partial class MainPage : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Model.Users user = Session["currUser"] as Model.Users;
if (user != null)
{
common.CommonCode.ExecuteScriptFunc(this,true);
}
else
{
common.CommonCode.ExecuteScriptFunc(this,false);
}
}
}
}

代码如下:

public static void ExecuteScriptFunc(System.Web.UI.Page page, bool bShowUserInfo)
{
string func = "function showUser(isLogin){\r\n\r\nif (isLogin) {\r\n" +
"$(\".loginDiv\").hide();\r\n" +
"$(\".loginOkDiv\").show();\r\n" +
"}\r\n" +
"else {\r\n" +
"$(\".loginDiv\").show();\r\n" +
"$(\".loginOkDiv\").hide();\r\n" +
"}}";
string func1 = "";
if (bShowUserInfo)
{
func1 = func + "\r\n" +
"$(function(){\r\nshowUser(true)" +
"});";
}
else
{
func1 = func + "\r\n" +
"$(function(){\r\nshowUser(false)" +
"});";
}
page.ClientScript.RegisterStartupScript(page.GetType(), Guid.NewGuid().ToString(),
func1, true);
//page.ClientScript.RegisterStartupScript(page.GetType(), Guid.NewGuid().ToString(),
// func1);
}

代码如下:

<img src="/01.jpg"> ../ 表示切换到上一级目录 http://localhost:2008/01.jpg
<img src="/blog_article/01.jpg"> ./或者 不填 表示当前路径 http://localhost:2008/websit1/01.jpg
<img src="/01.jpg"> / 表示根目录 返回的是网站的根目录 http://localhost:2008/01.jpg

代码如下:

Response.Write(Request.MaopPath("~/01.jpg")) 获得的是Response.Write(Request.MapPath("/01.jpg")); 相同的物理路径

代码如下:

public static void sendEmail(string toAddress, string emailbody)
{
var fromAddress = ConfigurationManager.AppSettings["EmailAddress"];
string fromPassword = ConfigurationManager.AppSettings["EmailPassword"].ToString();
const string subject = "Job Recommendation";


var smtp = new SmtpClient
{
Host = ConfigurationManager.AppSettings["SmtpServer"].ToString(),
Port = int.Parse(ConfigurationManager.AppSettings["SmtpPort"]),
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential(fromAddress, fromPassword)
};
using (var message = new MailMessage(fromAddress, toAddress, subject, HttpUtility.HtmlEncode(emailbody)))
{
smtp.Send(message);
}
}

<add key="EmailAddress" value="**********@gmail.com"/>//Email Address
<add key="EmailPassword" value="*********"/> //Emial PWD
<add key="SmtpServer" value="smtp.gmail.com"/>
<add key="SmtpPort" value="587"/>

<--带附件版本->

var fromAddress = "allenyinj@gmail.com";
string fromPassword = "yj1989120";
const string subject = "CV";


var smtp = new SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Credentials = new NetworkCredential(fromAddress, fromPassword)
};
MailMessage email=new MailMessage(fromAddress, "allen.yin.jun@gmail.com");
email.Subject = "INLINE attachment TEST";
email.IsBodyHtml = true;
string attachmentPath = "C:\\3.jpeg";
Attachment inline = new Attachment(attachmentPath);
inline.ContentDisposition.Inline = true;
inline.ContentDisposition.DispositionType = DispositionTypeNames.Inline;
//inline.ContentId = "1";
//inline.ContentType.MediaType = "image/png";
inline.ContentType.Name = Path.GetFileName(attachmentPath);
email.Attachments.Add(inline);
email.Body = "test";
smtp.Send(email);

email.Dispose();

//如果没有路径，用Stream

Attachment letter = new Attachment(FileUploadLetter.FileContent, FileUploadLetter.PostedFile.ContentType);
letter.ContentDisposition.Inline = true;
letter.ContentDisposition.DispositionType = DispositionTypeNames.Inline;
//inline.ContentId = "1";
letter.ContentType.MediaType = FileUploadLetter.PostedFile.ContentType;
letter.ContentType.Name = Path.GetFileName(FileUploadLetter.PostedFile.FileName);
letter.Name = Path.GetFileName(FileUploadLetter.PostedFile.FileName);

//如果希望通过匿名邮件发送 则

var smtp = new SmtpClient
{
Host = "serverName",
Port = 25, //匿名发送端口
EnableSsl = false,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
//Credentials = new NetworkCredential(fromAddress, fromPassword)
};
