Generate EmployeeID in C#

Today, I am providing the code to Generate Employee ID through which you will come to know the Date and Time on which that Employee is added to your database.

public void GenerateEmployeeID()
{
       string day, month, year, ID;
       string hr, min, sec;
       day = DateTime.Now.Date.Day.ToString();
       month = DateTime.Now.Month.ToString();
       year = DateTime.Now.Year.ToString();

       hr = DateTime.Now.Hour.ToString();
       min = DateTime.Now.Minute.ToString();
       sec = DateTime.Now.Second.ToString();

       txtEmpID.Text = "E-" + day + month + year + hr + min + sec;
}
