Dialogflow Webhook响应c＃在调用时给出错误-Java 学习之路

我正在尝试在C＃中创建一个用于Dialogflow的webhook（在Azure上） . 每次我看到相同的例子，但我的DialogFlows一直在使用这个响应做出错误“

这是我做的：

创建了一个新的ASP.Net Web项目（WebAPI）
安装了NuGet Google.Cloud.DialogFlow V2（v1.0.0.beta02）
将System.Net.Http更新为4.3.3

创建了一个新的控制器

[System.Web.Http.HttpPost]
    public dynamic DialogAction([FromBody] WebhookRequest dialogflowRequest)
    {
        var intentName = dialogflowRequest.QueryResult.Intent.DisplayName;
        var actualQuestion = dialogflowRequest.QueryResult.QueryText;
        var testAnswer = $"Dialogflow Request for intent {intentName} and question {actualQuestion}";
        var parameters = dialogflowRequest.QueryResult.Parameters;
        var dialogflowResponse = new WebhookResponse
        {
            FulfillmentText = testAnswer,
            FulfillmentMessages =
            { new Intent.Types.Message
                { SimpleResponses = new Intent.Types.Message.Types.SimpleResponses
                    { SimpleResponses_ =
                        { new Intent.Types.Message.Types.SimpleResponse
                            {
                                DisplayText = testAnswer,
                                TextToSpeech = testAnswer,
                            }
                        }
                    }
                }
            }                
        };
        var jsonResponse = dialogflowResponse.ToString();
        return new ContentResult
        {
            Content = jsonResponse,
            ContentType = "application/json"                
        };

将应用程序发布到Azure，因此有一个webhook URl . 现在，当我在对话框流中测试它时，响应是：

“Webhook调用失败 . 错误：无法解析webhook JSON响应：无法找到字段：消息中的内容google.cloud.dialogflow.v2.WebhookResponse . ”

哪些我不明白.....我在这里失踪了什么？

这个问题的解决方案是返回JsonResult而不是ContentResult .

[System.Web.Http.HttpPost]
public JsonResult DialogAction([FromBody] WebhookRequest dialogflowRequest)
{
    var intentName = dialogflowRequest.QueryResult.Intent.DisplayName;
    var actualQuestion = dialogflowRequest.QueryResult.QueryText;
    var testAnswer = $"Dialogflow Request for intent {intentName} and question {actualQuestion}";
    var parameters = dialogflowRequest.QueryResult.Parameters;
    var dialogflowResponse = new WebhookResponse
    {
        FulfillmentText = testAnswer,
        FulfillmentMessages =
        { new Intent.Types.Message
            { SimpleResponses = new Intent.Types.Message.Types.SimpleResponses
                { SimpleResponses_ =
                    { new Intent.Types.Message.Types.SimpleResponse
                        {
                            DisplayText = testAnswer,
                            TextToSpeech = testAnswer,
                        }
                    }
                }
            }
        }                
    };
    var jsonResponse = dialogflowResponse.ToString();
    return Json(jsonResponse);
