GraphQL客户端查询对象列表和变量

Question

我无法处理从一个查询接收数据并向其添加参数的情况。

我的课：

 public class DistributorProduct
    {
        public string id { get; set; }
        public string ean { get; set; }
        public int salesMultiple { get; set; }
        public int moq { get; set; }
        public float price { get; set; }
        public int stock { get; set; }
    }

一个对我有用的例子：

var request2 = new GraphQLRequest
            {
                Query = @"
              query {
                    getDistributorProduct( id: 110822 ) {
                    id
                    price
                      ean
                      price
                    }
                }"
            };

            var graphQLClient = new GraphQLClient("####");
            var graphQLResponse = await graphQLClient.PostAsync(request2);
            var responseType = graphQLResponse.GetDataFieldAs<DistributorProduct>("getDistributorProduct");
            var ean = responseType.ean;

我可以将其投放到班上，一切似乎都很好。

一个不适合我的示例：

 var request1 = new GraphQLRequest
            {
                Query = @"
                     query {
                        getDistributorProductListing {
                        totalCount
                            edges {
                                node {
                                    id
                                    ean
                                    }
                                  }
                        }
                    }"
            };

            var graphQLClient = new GraphQLClient("###");
            var graphQLResponse = await graphQLClient.PostAsync(request1);
            var responseType = graphQLResponse.GetDataFieldAs<DistributorProduct[]>("getDistributorProductListing"); 

            Console.WriteLine(responseType.Length.ToString());

我不太了解所返回的内容。 我遇到错误：

System.AggregateException
  HResult=0x80131500
  Message=One or more errors occurred. (Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type '###.Data.DistributorProduct[]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<T>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
Path 'getDistributorProductListing.totalCount'.)

Inner Exception 1:

我认为将返回对象数组，但JSON则相反。

我一直在寻找客户端边缘和节点文档，但找不到。

这是失眠症的结果：

＃

第二个问题是我无法在查询中添加“” ean“”，这在失眠的屏幕快照中可见。 我尝试过：

 Query = @"
              query MojeQuery($ean: ean) {
getDistributorProductListing( sortBy: ean  ) {
totalCount
edges {
                    node {
                    id
ean
                }
            }
}
    }",
                Variables = {
                    ean = "\"ean\""
                }

但是出现错误：

System.AggregateException
  HResult=0x80131500
  Message=One or more errors occurred. (Cannot perform runtime binding on a null reference)
  Source=System.Private.CoreLib
  StackTrace:

Inner Exception 1:

编辑

Okey，我已修复它。

  var responseType = graphQLResponse.GetDataFieldAs<DistributorProductConnection>("getDistributorProductListing");

新类，与我能够找到的客户文档一致！

但是，我仍在尝试将参数传递给查询
