    Code:

                MicrosoftAppCredentials.TrustServiceUrl(@"https://sms.botframework.com", DateTime.MaxValue);

                Trace.TraceInformation($"Incoming Activity is {activity.ToJson()}");

                if (activity.Type == ActivityTypes.Message)

我正在Bot框架中实现Microsoft语言翻译器，并且还实现了语言理解服务（Luis）。在我的代码中，一旦用户向机器人发送了一条消息，语言翻译器便会先检测用户语言，然后再在根对话框中将其发送给LUIS（我的LUIS应用程序是英语），然后机器人将响应翻译回用户语言使用状态数据。

在我使用表单流之前，一切工作都很好，如果不是英文单词，则由bot用户在表单流中输入的某些文本将被翻译成其他一些语言。请如何在不删除语言翻译API的情况下更正此问题？

注意：我的RootDailog中有一个调用表单流的部分。无论如何，我可以阻止语言翻译器API翻译表单输入吗？

如果堆栈中的最后一个对话框是FormFlow对话框，则可以检查对话框堆栈，而不进行翻译。像这样：

bool translate = true;
using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container, activity))
{
    var botData = scope.Resolve<IBotData>();
    await botData.LoadAsync(default(CancellationToken));

    var stack = scope.Resolve<IDialogTask>();
    if (stack.Frames != null && stack.Frames.Count > 0)
    {
        var lastFrame = stack.Frames[stack.Frames.Count - 1];
        var frameValue = lastFrame.Target.GetType().GetFields()[0].GetValue(lastFrame.Target);
        if (frameValue.GetType() == typeof(FormDialog<SandwichOrder>))
        {
            //in the FormFlow dialog ... do NOT translate
            translate = false;
        }
    }
}
if (translate)
{
    //translate activity.Text to English before sending to LUIS for intent
    activity.Text = TranslationHandler.TranslateTextToDefaultLanguage(activity, userLanguage);
}
await Conversation.SendAsync(activity, MakeRoot);
