如何在c#中使用LUIS None Intent而无需在LUIS训练发声

using Microsoft.Azure.CognitiveServices.Language.LUIS.Runtime;

var credentials = new ApiKeyServiceClientCredentials("YOUR_SUBSCRIPTION_KEY");
var client = new LUISRuntimeClient(credentials) { Endpoint = "https://YOUR_LUIS_ENDPOINT/api/v2.0" };

var appId = "YOUR_LUIS_APP_ID";
var predictionRequest = new PredictionRequest { Query = "YOUR_QUERY" };

var predictionResponse = await client.Prediction.GetSlotPredictionAsync(appId, "production", predictionRequest);

var topIntent = predictionResponse.Prediction.TopIntent;

if (topIntent == "None")
{
    // 执行相应的操作，处理无法识别的意图
}
else
{
    // 处理其他意图
}
