.net GraphQL客户端正在重新调整C中的空数据#

我在服务器端定义了一个查询

public TradeQuery(ITradeService tradeservice)
    {
        Name = nameof(TradeQuery);
        Field<ListGraphType<TradeType>>("trades", resolve: r => { return tradeservice.GetTrades(); });
    }

得到的回应是

{"data": {
    "tradeQuery": {
      "trades": [
        {
          "id": 3,
          "price": 600,
          "quantity": 600
        },
        {
          "id": 4,
          "price": 100,
          "quantity": 100
        }]}}}

但当我尝试使用

GraphQLHttpClient

调用相同的查询时，它返回为null 在下面的代码中，我在

availableTrades

对象中得到空值

 string apiEndpoint = "https://localhost:44342/graphql";

            var graphQLClient = new GraphQLHttpClient(new GraphQLHttpClientOptions { 
                EndPoint = new Uri (apiEndpoint)
            }, new NewtonsoftJsonSerializer());

            var tradeQuery = @"{
                              tradeQuery{
                               trades {
                                id
                                price
                                quantity}}}";
            GraphQLRequest graphQLRequest = new GraphQLRequest(tradeQuery);
            var tradeQueryResponse = await graphQLClient.SendQueryAsync<TradeQuery>(graphQLRequest);
            var availableTrades = tradeQueryResponse.Data.Trades;

你能告诉我哪里可能出了问题吗？

它在失眠中很有效。没有身份验证实现我认为json的去验证存在问题。当我使用SendQueryAsync（动态）时，它工作了。你们知道我们如何避免使用dynamic，并将其放入所需的对象中吗。

 string apiEndpoint = "https://localhost:44342/graphql";

            var graphQLClient = new GraphQLHttpClient(new GraphQLHttpClientOptions { 
                EndPoint = new Uri (apiEndpoint)
            }, new NewtonsoftJsonSerializer());

            var tradeQuery = @"{
                              tradeQuery{
                               trades {
                                id
                                price
                                quantity}}}";
            GraphQLRequest graphQLRequest = new GraphQLRequest(tradeQuery);
            var tradeQueryResponse = await graphQLClient.SendQueryAsync<TradeQuery>(graphQLRequest);
            var availableTrades = tradeQueryResponse.Data.Trades;

 public class TradeQuery
        {
            public List<Trade> Trades { get; set; }
        }
