[英]How to call a method from aspx.cs to another aspx.cs in same project?
我有2個aspx.cs頁面。 第一頁用於登錄,登錄后我調用發送和電子郵件作為提醒用戶登錄的方法。登錄后,您將移至第二頁。 我想在第二頁中創建另一個按鈕,當您按下它時,它將再次發送電子郵件(與第1頁中的發送方法相同)。 我可以在第2頁中從第1頁調用“發送”方法,還是必須在每頁中編寫整個方法?
這是后面的第1頁代碼:
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;
}
}
這是后面的第2頁代碼:
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??
}
}
怎么樣3:您在任何頁面中都沒有send方法,但是將其放在單獨的類中。
那是正確的編程習慣。
您需要執行以下任一方法:
創建一個基類,並在所有適當的aspx頁中繼承該基類。 (首選方法)
創建一個靜態類,並將其放在那里。
您可以像這樣使SendMail
方法static
:
public static string SendMail(string toList, string from, string ccList, string subject, string body)
現在您可以從任何地方調用它,只需將類名附加在前面,如下所示:
UserLogin.SendMail(toList, from, ccList, subject, body);
