C#(1.1)邮件发送类，功能全面，调用灵活、方便

Posted on 2007-07-28 14:04 laifangsong 阅读(1018) 评论(7) 编辑收藏

去网上搜c#邮件发送程序时，基本找到的都是零散的函数，没做封装，有的连异常处理都没有；能用的调用起来也不太灵活方便，所以，特地做了个封装。代码中如果有错误，欢迎指正。
以下是程序：

using System;

using System.Web.Mail;

using System.Collections;

namespace Asai.Mail

{

/// <summary>

/// C#邮件发送类 V1.0

/// --Author:laifangsong QQ:25313644

/// --最后修改：2007-07-27

///

/// 支持批量(发送、抄送、密送)

/// 支持多语言、带多个附件

/// 支持smtp发送邮件服务器验证

/// </summary>

public class DotNetSendMail

{

public DotNetSendMail()

{}

/// <summary>

/// 邮件发送结果。如果发送过程出现错误，该值为捕获到的异常提示；否则，该值为“OK”。

/// </summary>

public string SendMailResult

{

get

{

return this.m_SendMailResult;

}

set

{

this.m_SendMailResult = value;

}

private string m_SendMailResult;

邮件发送时，额外的功能属性设置

/// <summary>

/// 发送邮件方法,方法中几个参数是发邮件时所必须的

/// </summary>

/// <param name="p_From">发件人</param>

/// <param name="p_To">邮件人，多个收件人逗号隔开</param>

/// <param name="p_Subject">邮件标题</param>

/// <param name="p_Body">正文</param>

/// <param name="p_SmtpServer">发送邮件服务器</param>

/// <param name="p_SmtpUsername">发件服务器登录名</param>

/// <param name="p_SmtpPassword">发件服务器登录密码</param>

/// <returns></returns>

public bool SendMail(string p_From, string p_To, string p_Subject, string p_Body, string p_SmtpServer, string p_SmtpUsername, string p_SmtpPassword)

{

try

{

System.Web.Mail.MailMessage mail = new System.Web.Mail.MailMessage();

mail.From = p_From;

mail.To = p_To;

mail.Subject = p_Subject;

mail.Body = p_Body;

SmtpMail.SmtpServer = p_SmtpServer;

//邮件服务器验证，需要输入您在邮件发送服务器上注册的邮箱用户名和密码

if(p_SmtpUsername!="")

{

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", p_SmtpUsername);

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", p_SmtpPassword);

}

//以上是发邮件时所必需的，下面是额外的一些功能设置

if(this.m_Cc!="")

{

mail.Cc = this.m_Cc;

}

if(this.m_Bcc!="")

{

mail.Bcc = this.m_Bcc;

}

switch(this.m_BodyFormat)

{

case 1:

mail.BodyFormat = MailFormat.Html;

break;

case 2:

mail.BodyFormat = MailFormat.Text;

break;

default:

break;

}

switch(this.m_MailPriority)

{

case 1:

mail.Priority = System.Web.Mail.MailPriority.Low;

break;

case 2:

mail.Priority = System.Web.Mail.MailPriority.Normal;

break;

case 3:

mail.Priority = System.Web.Mail.MailPriority.High;

break;

default:

break;

}

if(this.m_AttachFiles.Count>0)

{

foreach(string file in m_AttachFiles)

{

if(file.Trim()!="")

{

mail.Attachments.Add(new MailAttachment(file.Trim()));

}

SmtpMail.Send(mail);

this.m_SendMailResult = "OK";

return true;

}

catch(Exception ex)

{

this.m_SendMailResult = ex.ToString();

return false;

}

调用：

DotNetSendMail sendMail = new DotNetSendMail();

//sendMail.Cc = "laifangsong##gmail.com";

//sendMail.Bcc = "laifangsong##gmail.com";

//sendMail.BodyFormat = 2;

//sendMail.MailPriority = 3;

//sendMail.AttachFiles.Add(Server.MapPath("attachFile.txt"));

bool sendResultFlag = sendMail.SendMail("laifangsong##126.com","laifs##163.com","标题","内容","smtp.126.com","laifangsong##126.com","123456");

if(sendResultFlag)

{

Response.Write("发送成功！");

}

else

{

Response.Write("发送失败！<br/>");

Response.Write("以下是错误信息：<br/><br/>");

Response.Write(sendMail.SendMailResult);

Response.End();

}
