小编use*_*592的帖子

当我尝试编译它时,下面的代码给出了一个错误"无效的表达式术语'else'".我无法弄清楚如何解决它:

public double CalcTicketCost(int section, double quantity)
{
    double amount = 0;

    if (int.Parse(lstSectionNumber.SelectedItem.Value) < 150)
    {
        amount = premiumTicket  * quantity;
        return amount;
    }
    {
        else  (int.Parse(lstSectionNumber.SelectedItem.Value) > 150) // This line is where the problem seems to be

        amount = basicTicket * quantity; 
    }
    return amount;
}
