.......等等

我已经编写了以下代码插入数据集，但它给出了错误。

 string url = "http:api.offers.com/Apiv3/json?NetworkId=inf&Target=Affiliate_Offer&Method=findAll&api_key=4bf7ba7b1904716179c9284cbd7db17018b8a5f";
            string JsonString = new WebClient().DownloadString(url);
            DataSet dataSet = JsonConvert.DeserializeObject<DataSet>(JsonString);
            DataTable dataTable = dataSet.Tables["request"];
            Console.WriteLine(dataTable.Rows.Count);
            foreach (DataRow row in dataTable.Rows)
            
                Console.WriteLine(row["Target"] + " - " + row["Format"]);
            

获取错误：

信息：读取 DataTable 时出现意外的 JSON 令牌。预期的 StartArray，得到了 StartObject。路径“请求”，第 1 行，位置 12。

所以，请帮我将 Json 转换为 Dataset，然后插入 SQL 数据库或直接插入 SQL 数据库。 我目前正在使用 newtonsoft.json。 出于我的目的，也欢迎其他简单的选项。

【参考方案1】：

反序列化器不知道如何处理 DataSet 类型。
