FlowSwitch<string> promoCodeSwitch = new FlowSwitch<string>
{
    Expression = promo,
    Cases =
    {
       { "Single", singleStep },
       { "MNK", mnkStep },
       { "MWK", mwkStep }
    },
    Default = discountDefault
};

備註

字典中的每個項目都是由在 FlowSwitch<T> 中所指定之泛型型別的物件，以及要執行的對應 FlowNode 所構成。Each element in the dictionary consists of an object of the generic type specified in FlowSwitch<T> and a corresponding FlowNode to execute.
