Question

我有2个aspx.cs页面。第一页用于登录，登录后我拨打方法发送和发送电子邮件作为用户所在的警报。登录后，您将转到第二页。我想在第二页中创建另一个按钮，当你按下它时，它会再次发送电子邮件（第1页的相同发送方法）。我是否可以在第2页中调用第1页的“发送”方法，或者我必须在每个页面中编写整个方法？

这是第1页代码：

public partial class UserLogin : System.Web.UI.Page
{
private string _employee;
private string _userName;
private string _loginDatetime;

protected void Page_Load(object sender, EventArgs e)
{

}

protected void LoginBtn_Click(object sender, EventArgs e)
{
    _employee = employeeBox.Text;
    _userName = userBox.Text;
    _loginDatetime = DateTime.Now.ToString();

    SendMail("your_email@gmail.com", "your_email@gmail.com", "your_email@gmail.com", "Login Alert",
        "Hello " + _employee + ",<Br>User \"" + _userName + "\" just log to the website on the following date: " + DateTime.Now);

    Response.Redirect("http://localhost:21361/UserDeposit.aspx?_employee=" + employeeBox.Text + "&_userName=" + userBox.Text + "&_loginDatetime=" + _loginDatetime);
}

protected string SendMail(string toList, string from, string ccList, string subject, string body)
{

    MailMessage message = new MailMessage();
    SmtpClient smtpClient = new SmtpClient();
    string msg;
    try
    {
        MailAddress fromAddress = new MailAddress(from);
        message.From = fromAddress;
        message.To.Add(toList);
        if (!string.IsNullOrEmpty(ccList))
            message.CC.Add(ccList);
        message.Subject = subject;
        message.IsBodyHtml = true;
        message.Body = body;
        smtpClient.Host = "smtp.gmail.com";   
        smtpClient.Port = 587;
        smtpClient.EnableSsl = true;
        smtpClient.UseDefaultCredentials = true;
        smtpClient.Credentials = new NetworkCredential("your_email@gmail.com", "password");

        smtpClient.Send(message);
        msg = "Successful";
        Response.Write("<script>alert('" + msg + "')</script>");
    }
    catch (Exception ex)
    {
        msg = ex.Message;
        Response.Write("<script>alert('" + msg + "')</script>");
    }
    return msg;
}
}

这是第2页的代码：

public partial class UserDeposit : System.Web.UI.Page
{
string _employeeName;
string _userName;
string _loginTime;
DateTime time;

protected void Page_Load(object sender, EventArgs e)
{
    _employeeName = Request.QueryString["_employee"];
    EmployeeName.Text = _employeeName;

    _userName = Request.QueryString["_userName"];
    UserName.Text = _userName;

    _loginTime = Request.QueryString["_loginDatetime"];
    time = DateTime.Parse(_loginTime);
}



protected void Button1_Click(object sender, EventArgs e)
{
    //call here the "send mail" method??
}
}

Answer 1

3：你没有在任何页面中使用send方法，而是把它放在一个单独的类中。

这是正确的编程实践。

Answer 2

您需要执行以下任一方法之一：

创建一个基页类并继承所有基页类适当的aspx页面。（首选方法）
创建一个静态类并将它们放在那里。

Answer 3

您可以像这样SendMail方法static：

public static string SendMail(string toList, string from, string ccList, string subject, string body)

现在你可以从任何地方调用它，只需在前面附加类名，如下所示：

UserLogin.SendMail(toList, from, ccList, subject, body);

如何在同一个项目中调用aspx.cs中的方法到另一个aspx.cs？
