                frm.Close();
                EmployeeDetails emp = new EmployeeDetails();
                emp.Show();
            }

推荐答案

假设你正确设置了Timer，我怀疑你想要的是取代

Assuming that somewhere you are setting up the Timer correctly, I suspect that what you want is to replace

timer1.Enabled = true;

With

count = 0;
timer1.Start();

并添加一个电话

And add a call to

timer1.Stop();

。

我猜你试图关闭错误的实例。



检查这些行：在你的计时器滴答方法

登录frm = new登录（）;

frm.Close（）;



我相信BtnSubmit_Click方法在Login类中。如果是，你应该调用this.Hide。

不要使用新实例来关闭。

I guess you are trying to close the wrong instance.

check these lines: in your timer tick method
Login frm = new Login();
frm.Close();

I believe the BtnSubmit_Click method is inside the Login class. If yes you should call the this.Hide.
do not use a new instance to close.
