简单的发送邮件功能 潜龙勿用

在互联网竞争日趋激烈的今天，邮箱成为了每位工作人士必不可少的一样辅助工具，我呢，每日都要发送邮件，对邮件的发送当然其原理也很简单，下面简单的实现以下发送的代码：

首先，设计了一下界面：

 <div >
   <table>
   <tr><td>收件人：</td><td><input type="text" id="ReceveEmail"  /></td></tr>
   <tr><td>主题：</td><td><input type="text" id="Themes" /></td></tr>
   <tr><td>附件：</td><td><input type="file" id="attach" name="attach" runat="server" /></td></tr>
   <tr><td>正文：</td><td><textarea cols="40" rows="10" id="Content"></textarea></td></tr>
   </table>
   <input type="button" id="SendEmail" value="发送"  onclick="SendEmail()"/><span id="Send" style="display:none" >Sending.....</span>
   </div>
   

这里呢，我是用Ajax来实现的，但是有一个问题没能解决，就是在Firefox下邮件的附件不能进行发送了很遗憾，希望各位大虾多多指教，当点击"发送"时，解释执行以下这段脚本

<script type="text/javascript" language="javascript">
    function SendEmail() {
        var ReceveEmail = $("#ReceveEmail").val();

        var Themes = $("#Themes").val();
        var Content = $("#Content").val();
        var Attach ='<%=FilePath %>';
        if (navigator.userAgent.indexOf("MSIE") != -1) {
            Attach = document.getElementById("attach").value;
        }
        else if (navigator.userAgent.indexOf("Firefox") != -1 || navigator.userAgent.indexOf("Mozilla") != -1) {
            try {
                netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
            }
            catch (e) {
                 alert('此操作被浏览器拒绝！请在浏览器地址栏输入"about:config"并回车然后将[signed.applets.codebase_principal_support]设置为"true"'); 
                return;
            }
            var  Attach= document.getElementById("attach").value;
//          var Attach = document.getElementById("attach").files[0].getAsDataURL();
            var file = Components.classes["@mozilla.org/file/local;1"]
        .createInstance(Components.interfaces.nsILocalFile);
            try {
                // Back slashes for windows
                file.initWithPath(Attach);
            }
            catch (e) {
                if (e.result != Components.results.NS_ERROR_FILE_UNRECOGNIZED_PATH) throw e;
                alert(' 无法加载文件 ');
                return;
            }
        }
        if (ReceveEmail != "" || Themes != "" || Content != "") {
            $.ajax({
                type: "POST",
                url: "../AjaxPro.aspx?_Action=SendEmail",
                data: { "ReceveEmail": escape(ReceveEmail), "Themes": Themes, "Content": Content, "Attach": Attach },
                beforeSend: function () {
                    $("#Send").show();
                },
                success: function (Msg) {                   
                    if (Msg) {
                        $("#Send").hide();
                        alert(Msg);
                    }
                }

            });
        }

    }


</script>

将值post到了"../AjaxPro.aspx?_Action=SendEmail"这个页面进行处理

///[code=csharp]
///[WebMethod]
/// <summary>
        /// 简单的邮箱发送功能
        /// </summary>
        public void SendEmail()
        {
            string ReceviceEmail=Request["ReceveEmail"].Trim().ToString();
            string Themes=Request["Themes"].Trim().ToString();
            string Content=Request["Content"].Trim().ToString();         
            string Attach = Request["Attach"].Trim().ToString();         
            string[] ToEmail=Regex.Split(ReceviceEmail,";",RegexOptions.IgnoreCase);
            string DisplayName = "";
            string Addre = "";
            MailMessage message = new MailMessage();
           //这里是对邮件群发的设置
            foreach (string Name in ToEmail)
            {
                if (Name != string.Empty)
                {
                    if (Name.IndexOf("<") > 0)
                    {
                        DisplayName = Name.Substring(0, Name.IndexOf("<"));
                        Addre = Name.Substring((Name.IndexOf("<") + 1)).Replace(">", "");
                        
                    }
                    else
                    {
                        DisplayName = string.Empty;
                        Addre = Name.Substring((Name.IndexOf("<") + 1)).Replace(">", "");
                    }
                    message.To.Add(new MailAddress(Addre,DisplayName));
                }
            }
           
            message.Attachments.Add(new Attachment(Attach));
            //设置邮箱的主题
            message.Subject = Themes;
            //设置邮箱主题内容的编码格式
            message.SubjectEncoding = Encoding.Default;
            //设置邮件的正文
            message.Body = Content;
            //设置邮件正文格式为默认的
            message.BodyEncoding = Encoding.Default;
            //设置邮件正文格式为UTF-8的
            //message.BodyEncoding = System.Text.Encoding.UTF8;
            message.IsBodyHtml = true;
            //邮件的发件人的地址
            message.From=new MailAddress("345686955@qq.com","孙旭柱");
            //设置此邮件的优先级
            message.Priority = MailPriority.Normal;

            //这里设置qq的SMTP服务器地址
            SmtpClient client = new SmtpClient();
            client.Host = "smtp.qq.com";
            //设置端口号
            client.Port = 25;
            client.UseDefaultCredentials = false;
            //获取或设置用于验证发件人身份的凭据
            client.Credentials = new System.Net.NetworkCredential("345686955@qq.com", "!sun3456");
            //制定如何处理待发的邮件
            client.DeliveryMethod = SmtpDeliveryMethod.Network;
            //发送邮件
            client.Send(message);
            Msg = "发送成功";



        }

就这样简单的邮箱发送功能就实现了，在火狐下要进行设置，在地址栏中输入about:confing然后按提示进行设置就可以了，当中对邮箱没有进行格式的验证，以及为空的验证，这里设置的是qqde SMTP的服务器地址，如有哪里写的不妥之处请来信指教

谢谢！
