问题
I have created one dialog to evaluate our company consultant in our chatbot (C# botframework), but I can't use for or foreach inside of AdaptiveCard. I need to create one TextBlock() and one ChoiceSet() block for each item from List Pergunta, but I can't do it with foreach. Any suggestion or better idea to create this loop ?
Here is my complete dialog code in C#.
using System;
using System.Threading.Tasks;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Connector;
using System.Collections.Generic;
using AdaptiveCards;
using SimpleEchoBot.Formulário;
namespace SimpleEchoBot.Dialogs
{
[Serializable]
public class RatingDialog : IDialog<EntidadeCliente>
{
public Task StartAsync(IDialogContext context)
{
context.Wait(this.MessageReceivedAsync);
return Task.CompletedTask;
}
public async virtual Task MessageReceivedAsync(IDialogContext context, IAwaitable<IMessageActivity> result)
{
var replyMessage = context.MakeMessage();
Attachment attachment = null;
attachment = CriarAdapativecard();
replyMessage.Attachments = new List<Attachment> { attachment };
await context.PostAsync(replyMessage);
}
public Attachment CriarAdapativecard()
{
AdaptiveCard card = new AdaptiveCard()
{
Body = new List<CardElement>()
{
new Container()
{
Items = new List<CardElement>()
{
new ColumnSet()
{
Columns = new List<Column>()
{
new Column()
{
Size = ColumnSize.Auto,
Items = new List<CardElement>()
{
new Image()
{
Url = "D:/EvaWeb.png",
Size = ImageSize.Medium,
Style = ImageStyle.Person
}
}
},
new Column()
{
Size = ColumnSize.Auto,
Items = new List<CardElement>()
{
new TextBlock()
{
Text = "Olá, temos uma novidade!",
Weight = TextWeight.Bolder,
IsSubtle = true
},
new TextBlock()
{
Text = "Gostaria de iniciar a avaliação do consultor?",
Wrap = true
}
}
}
}
}
}
}
},
// Buttons

{
new ShowCardAction()
{

Card = AvaliarConsultor("")
},
new ShowCardAction()
{
Title = "Não",
Speak = "<s>Não</s>",
Card = PularAvaliacao()
},
}
};
Attachment attachment = new Attachment()
{
ContentType = AdaptiveCard.ContentType,
Content = card
};
return attachment;
}
private static AdaptiveCard PularAvaliacao()
{
//does nothing on No option from user
return new AdaptiveCard()
{ };
}
private static AdaptiveCard AvaliarConsultor(List<string> Pergunta)
{
var adaptiveCard = new AdaptiveCard()
{

{
new TextBlock()
{

Weight = TextWeight.Bolder,
Size = TextSize.Large
},
new TextBlock() { Text = Pergunta[0]},
new ChoiceSet()
{
Id = "nota",
Style = ChoiceInputStyle.Compact,
IsMultiSelect = false,
Choices = new List<Choice>()
{
new Choice()

new Choice()

new Choice()
{
Title = "⭐⭐⭐⭐",
Value = "4"
},
new Choice()
{
Title = "⭐⭐⭐⭐⭐",

}
}
}

I need to create one TextBlock() and one ChoiceSet() block for each item from List Pergunta, but I can't do it with foreach.
To achieve your requirement, please refer to the following code snippet.
private static AdaptiveCard AvaliarConsultor(List<string> Pergunta)
{
var adaptiveCard = new AdaptiveCard()
{
Body = new List<CardElement>()
{
new TextBlock()
{
Text = "Avaliação de questionário 1!",
Weight = TextWeight.Bolder,
Size = TextSize.Large
},
},
Actions = new List<ActionBase>()
{
new SubmitAction()
{
Title = "Registrar",
Speak = "<s>Registrar avaliação</s>",
DataJson = "{ \"Type\": \"Registrar\" }"
}
}
};
//dynamically generate TextBlock and ChoiceSet
//and then add to AdaptiveCard Body
foreach (var item in Pergunta)
{
var textblock = new TextBlock() { Text = item };
var choiceset = new ChoiceSet()
{
Id = "nota",
Style = ChoiceInputStyle.Compact,
IsMultiSelect = false,
Choices = new List<Choice>()
{
new Choice()
{
Title = "⭐",
Value = "1"
},
new Choice()
{
Title = "⭐⭐",
Value = "2"
},
new Choice()
{
Title = "⭐⭐⭐",
Value = "3"
},
new Choice()
{
Title = "⭐⭐⭐⭐",
Value = "4"
},
new Choice()
{
Title = "⭐⭐⭐⭐⭐",
Value = "5"
}
}
};
adaptiveCard.Body.Add(textblock);
adaptiveCard.Body.Add(choiceset);
}
return adaptiveCard;
}
