asp.net实现发送邮件

private void Page_Load(object sender, System.EventArgs e)
{
string sReturn = string.Empty;
MailMessage mailMsg = new MailMessage();
mailMsg.BodyFormat = MailFormat.Html;
mailMsg.To = "****@163.com";

// mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "用户名");
// mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "密码");
//
SmtpMail.SmtpServer ="smtp.126.com";//smpt服务器
try
{

SmtpMail.Send(mailMsg);
this.Label1.Text = "发送成功";
}
catch (Exception err)
{
this.Label2.Text = "<font color=red>发送失败" + err.Message.ToString() + "</font>";

提问者对于答案的评价：
谢谢给我传过来的资料
下面是我亲手写的测试发邮件的：
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.Net.Mail;

namespace Logic
{
public class Mail
{
public bool ServiceSendMail(string strTo, string strSubject, string strBody, string strEncoding)
{
return common(strTo, "", strSubject, strBody, strEncoding);
}

/// <summary>
/// 邮件发送(Service邮箱),默认编码为GB2312
/// </summary>
/// <param name="strTo"></param>
/// <param name="strCc"></param>
/// <param name="strSubject"></param>
/// <param name="strBody"></param>
/// <param name="strEncoding">编码，如果为空，默认为GB2312</param>
/// <returns></returns>
public bool ServiceSendMail(string strTo, string strCc, string strSubject, string strBody, string strEncoding)
{
return common(strTo, strCc, strSubject, strBody, strEncoding);
}

/// <summary>
/// 邮件发送默认编码为GB2312
/// </summary>
/// <param name="strTo"></param>
/// <param name="strSubject"></param>
/// <param name="strBody"></param>
/// <returns></returns>
public bool ServiceSendMail(string strTo, string strSubject, string strBody)
{
return common(strTo, "", strSubject, strBody, "");
}

private static bool common(string strTo, string strCc, string strSubject, string strBody, string strEncoding)
{
bool bState = false;

try
{
//编码暂硬性规定为GB2312
Encoding encoding = Encoding.GetEncoding(936);

MailMessage Message = new MailMessage(
new MailAddress("[e-mail]", "hanjunhui127", encoding),
new MailAddress(strTo));

Message.SubjectEncoding = encoding;
Message.Subject = strSubject;
Message.BodyEncoding = encoding;
Message.Body = strBody;
if (strCc != "")
{
Message.CC.Add(new MailAddress(strCc));
}
SmtpClient smtpClient = new SmtpClient("smtp.sina.com");
smtpClient.Credentials = new NetworkCredential("hanjunhui127","1984127");
smtpClient.Timeout = 999999;
smtpClient.Send(Message);

bState = true;

}
catch (Exception ex)
{
throw new Exception(ex.Message);
}

return bState;
}

 

}
}

你把上面的代码编译成dll,在web程序里面引用那个dll
在aspx.cs里面你可以这样写
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Logic;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Logic.Mail m = new Mail();
m.ServiceSendMail("[e-mail]", "你好", "我好啊```````````````");
Response.Write("成功!");
}
}

上面我已经测试成功
如果不行，请继续参考下面的文章
你可以先参考一下这两文章：

测试过 好用的(MailInfo 是个实体用来存用户信息的)

是用Jmail

End Sub

Function SendMail() As Boolean
Dim smtpServer As String = ConfigurationSettings.AppSettings("smtpServer")

Dim result As Boolean
Dim oJmail As New jmail.MessageClass

oJmail.MailServerPassWord = smtpPass

'oJmail.Body = Request("Content")
oJmail.AppendHTML(Request("Content").ToString)

'遍历File表单元素
Dim files As System.web.HttpFileCollection = System.Web.HttpContext.Current.Request.Files

oJmail.AddAttachment(filename, False, filename.Substring(filename.LastIndexOf(".") + 1, 3))
End If
Next
Catch Ex As System.Exception
Label1.CssClass = "red"

'参数title是标题，Boby内容，TOWHO要发送给的邮件地址,发送成功返回空，发送失败返回错误消息
VB.NET做法
Public Function SendMail(ByVal title As String, ByVal Body As String, ByVal ToWho As String) As String
Dim Msg As New MailMessage
Msg.From = "你的邮件地址"
Msg.To = ToWho
Msg.Subject = title
Msg.BodyFormat = MailFormat.Html

Msg.Priority = MailPriority.High
Msg.Body = Body
Msg.Fields.Add("

Msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "你的邮箱登录名称")

Try
System.Web.Mail.SmtpMail.SmtpServer = "邮件服务器地址，如smtp.126.com"
System.Web.Mail.SmtpMail.Send(Msg)
SendMail = ""
Catch ex As Exception

c#做法
public string SendMail(string title,string body,string towho)
