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(3680)  评论(9编辑  收藏  举报

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_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(

                    mail.Fields.Add(

                    mail.Fields.Add(

                }

                
                
//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;

                }

                
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();
}
