如何在创建SharePoint列表时触发代码？

public override void ItemAdded(SPItemEventProperties properties)
{
    // 获取当前用户的电子邮件地址
    string userEmail = properties.Web.CurrentUser.Email;

    // 创建电子邮件对象
    MailMessage mailMessage = new MailMessage();
    mailMessage.To.Add(userEmail);
    mailMessage.Subject = "新的SharePoint列表已创建";
    mailMessage.Body = "您已成功创建一个新的SharePoint列表。";

    // 创建SMTP客户端
    SmtpClient smtpClient = new SmtpClient("smtp.example.com", 25);
    smtpClient.Credentials = new NetworkCredential("username", "password");

    // 发送电子邮件
    smtpClient.Send(mailMessage);
}
