PromptDialog.Choice 之后的操作

Question

这应该不会太难，但我是 C# 新手，似乎无法修复它。如果用户希望将输入发送到数据库，我有一个 Prompt.Dialog.Choice 来确认一条消息。我被困在 ChoiceReceivedAsync 中，我想在那里进行操作，无论用户是否回答“是”或“否”，但是我如何在 if-else 语句中调用这些答案？这是相关的代码：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}    }

Answer 1

您只需将结果 ( 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

    }

}
