你忘记了id。

public void Updateemployee(employeeView model)
    {
        using (var emprep = new employeeRepository())
        {
            var employee= new employee();


            if (emp != null)
            {
                //here  
                `enter code here`emp=emprep.GetById(model.emp_Id);

                emp.employee_Name = model.employee_Name;
                emp.employee_Address = model.employee_Address;
                emp.Email = model.Email;
                emp.Contact_No = model.Contact_No;
                emp.Update(emp);
            }
        }
    }
