由于我没有更改代码,而且我今天早上使用它没有问题,我不太确定会发生什么。任何帮助都将不胜感激。

更新:

2) 大多数逻辑存在于我的LUIS对话框和其他特定对话框中,这些对话框根据意图启动:

[LuisIntent("Power.Buy")]
public async Task PowerTrade(IDialogContext context, IAwaitable<IMessageActivity>activity, LuisResult result)
{            
  BaseTrade formState = BaseTrade.InitState(result);
  formState.PositionType = PositionType.Buy;           

  SetCommonFields(formState);

  var tradeFormDialog = new FormDialog<BaseTrade>(formState, _tradeCreationDelegate, FormOptions.PromptInStart);            
  context.Call(tradeFormDialog, TradeTypeSpecificsDialog);
}

BaseTrade模型:

public enum PositionType
{
    Buy, Sell, Swap              
}

public enum Unit
{
    Mw,
    Mwh,
    Gj,
    Mmbtu
}
public enum Timezone
{
    APT = 1,
    AST,
    CPT,
    CST,
    EPT,
    EST,
    GMT,
    MPT,
    MST,
    PPT,
    PST
}

[Serializable]
public class BaseTrade
{

    [Prompt("Position Type?")]
    public PositionType? PositionType;

    [Prompt("Who is the counterparty?")]
    public string Counterparty;         

    [Prompt("Start date?")]
    public DateTime StartDate;

    [Prompt("End date?")]
    public DateTime EndDate;

    public Timezone Timezone;

    [Prompt("Please enter the trade quantity")]
    public int? Quantity;

    public Unit? Unit;

    [Prompt("Price?")]
    public int? Price;

    public DateTime? TradeDate = new DateTime();

    public static IForm<BaseTrade> BuildForm()
    {
        return new FormBuilder<BaseTrade>().Message("OK, we are going to create a trade").Build();
    }
