Mailmessage+smtpclient发送电子邮件时密码写在哪里？

[qufo]

如下代码：
MailMessage msg = new MailMessage("[e-mail]", "[e-mail]", "Subject:Test", "Body:Test");
SmtpClient smtp = new SmtpClient("smtp.163.com");
smtp.Credentials = CredentialCache.DefaultNetworkCredentials;

try
{
smtp.Send(msg);
}
catch (Exception exx)
{
MessageBox.Show(exx.Message);
}

可是，我的[e-mail]的邮件登录密码写在哪？不写密码肯定发不出去呀。

不需要登陆你的[e-mail]的密码

有smtp服务就能发送出去. (也就是常说的垃圾邮件...)

[z_liwu]

mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", _usename); //set your username here
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", _userpwd); //set your password here

smtp.Credentials = new System.Net.NetworkCredential("[e-mail]", "password");

补充:

Smtp服务器,可用本地的也可以用其它的可用有Smtp服务器.
（1）如果用本地的，本地要装Smtp服务也就是系统组件，默认没有安装。
（2）如果用邮件服务商的，你要有其上面的帐号与密码。

SmtpClient.Credentials 属性:获取或设置用于验证发件人身份的凭据。

public static void CreateTestMessage1(string server, int port,string userName,string password)
{
string to = "[e-mail]";
string from = "[e-mail]";
string subject = "Using the new SMTP client.";
string body = @"Using this new feature, you can send an e-mail message from an application very easily.";
MailMessage message = new MailMessage(from, to, subject, body);
SmtpClient client = new SmtpClient(server, port);
// Credentials are necessary if the server requires the client
// to authenticate before it will send e-mail on the client's behalf.
client.Credentials = new System.Net.NetworkCredential(userName, password);

client.Send(message);
}

1.x和2.0是不同的

2.0写在配置文件里面就行了
1.x需要添加Field
