Can we use single class object twice in single method

Question

if (User.Count != 0 || Email.Count != 0)
{
    Session["EmailErrorMessage"] = "Username or Email already exists";
}

else if (User != null && UserMail != null && Designation != 5)
{
    var employee = new Employees()
    {
        EmployeeID = UserName,
        Password = encerptd,
        Email = UserMail,
        FirstName = UserFirstName,
        LastName = UserLastName,
        Role = (int)Helpers.GlobalsVariables.Role.Entry,
        IsActive = true,
        CreatedDate = DateTime.Now,
        CreatedBy = 1,
        ModifiedBy = 1,
        Manager = Manager,
        ModifiedDate = DateTime.Now,
        Designation = UserDesignation
    };
    int employeeID = _employees.InsertAndReturnPk(employee);
    Session["successMessage"] = "User has been Created Successfully";
}
else
{
    var employee = new Employees()
    {
        EmployeeID = UserName,
        Password = encerptd,
        Email = UserMail,
        FirstName = UserFirstName,
        LastName = UserLastName,
        IsActive = true,
        Role = (int)Helpers.GlobalsVariables.Role.Admin,
        CreatedDate = DateTime.Now,
        CreatedBy = 1,
        ModifiedBy = 1,
        ModifiedDate = DateTime.Now,
        Designation = UserDesignation,
