我已经创建了一个对话框来评估我们的聊天机器人（C＃botframework）中的公司顾问，但是我不能在AdaptiveCard中使用foreach或foreach。我需要为List Pergunta中的每个项目创建一个TextBlock（）和一个ChoiceSet（）块，但是我无法使用foreach来实现。有什么建议或更好的主意来创建此循环吗？
这是我在C＃中完整的对话框代码。

我需要为List Pergunta中的每个项目创建一个TextBlock（）和一个ChoiceSet（）块，但是我无法使用foreach来实现。
要满足您的要求，请参考以下代码段。
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;
}
