Question

这应该不太困难，但是我是C＃的新手，似乎无法修复它。我有一个Prompt.Dialog.Choice来确认消息，如果用户希望将输入发送到数据库。

我被困在ChoiceReceivedAsync中，我想在此环境中采取行动，或者用户是否回答“是”或“否”，但是我该如何在if-else句子中称呼这些答案？

以下是相关代码：

public enum booleanChoice { Yes, No }

public async Task StartAsync(IDialogContext context)
    {
        //var message = await result as IMessageActivity;
        await context.PostAsync("Do you want you message to be sent?");

        PromptDialog.Choice(
            context: context,
            resume: ChoiceReceivedAsync,
            options: (IEnumerable<booleanChoice>)Enum.GetValues(typeof(booleanChoice)),
            prompt: " ",
            retry: "Please try again.",
            promptStyle: PromptStyle.Auto
        );
    }

public async Task ChoiceReceivedAsync(IDialogContext context, IAwaitable<booleanChoice> result)
    {
        booleanChoice response = await result;

        //Here's where I'm stuck:
        //if (PromptDialog.Choice == "Yes"){//send the inputs to the databse}
        //else (PromptDialog.Choice == "No"){//exit or enter the message again}


    }

您只需要将结果（response）与枚举值进行比较，如下所示：

public async Task ChoiceReceivedAsync(IDialogContext context, IAwaitable<booleanChoice> result)
{
    booleanChoice response = await result;

    if (response.Equals(booleanChoice.Yes))
    {
        //send the inputs to the databse}
    else 
    {
        //exit or enter the message again
    }
}

PromptDialog.Choice之后的动作
