ASP.Net发送电子邮件时如何在代码中隐藏密码？

为了避免在代码中显式地显示电子邮件的密码，可以将密码存在Web.Config文件中，并在代码中调用。

在Web.Config文件中添加以下行：

<appSettings> <add key="EmailUsername" value="username" /> <add key="EmailPassword" value="password" /> </appSettings>

在代码中调用：

using System.Configuration; using System.Net.Mail;

var username = ConfigurationManager.AppSettings["EmailUsername"]; var password = ConfigurationManager.AppSettings["EmailPassword"];

var message = new MailMessage(); message.From = new MailAddress("sender@example.com"); message.To.Add(new MailAddress("recipient@example.com")); message.Subject = "Subject"; message.Body = "Body";

var client = new SmtpClient(); client.Host = "smtp.example.com"; client.Port = 587; client.EnableSsl = true; client.Credentials = new NetworkCredential(username, password); client.Send(message);
