示例

下面的代码示例演示如何在 Flowchart 活动中使用 Variables。 此示例摘自 使用 TryCatch 的流程图活动中的错误处理 示例。

Flowchart flowChart = new Flowchart
{
    DisplayName = "Promotional Discount Calculation",
    Variables = {discount, promo, numberOfKids},
    StartNode = promoCodeSwitch,
    Nodes =
    {
        promoCodeSwitch,
        singleStep,
        mnkStep,
        mwkStep,
        discountDefault,
        flowDecision,
        discountApplied,
        discountNotApplied
    }
};
