Question

我试图将以下内容反序列化为C＃类：

{
    "response" : {
        "" : {
            "Expense" : [[{
                        "chart_of_accounts_id" : "45f2fd8f-68b2-44cc-b07ac031c97cd96c",
                        "account_name" : "Salaries",
                        "amount" : "1500.00",
                        "entry_type" : "Debit",
                        "business_id" : "528f00bb-8cd8-4e7f-be6a-0724c327a7be",
                        "account_category" : "5"
                    }, {
                        "chart_of_accounts_id" : "45f2fd8f-68b2-44cc-b07ac031c97cd96c",
                        "account_name" : "Salaries",
                        "amount" : "200.00",
                        "entry_type" : "Debit",
                        "business_id" : "528f00bb-8cd8-4e7f-be6a-0724c327a7be",
                        "account_category" : "5"
                    }
                ]]
        }
    },
    "messages" : {
        "msgs" : "",
        "errs" : ""
    }
}

到目前为止我有以下内容，但是我收到错误“无法将当前JSON对象（例如{”name“：”value“}）反序列化为类型'Systems.Collections.Generic.List'1 [eko_app.Expenses + ExpensesResponse]'因为它需要一个JSON数组（例如[1,2,3]）才能正确反序列化“

public class Expense
{
    public string chart_of_accounts_id { get; set; }
    public string account_name { get; set; }
    public decimal amount { get; set; }
    public string entry_type { get; set; }
    public string business_id { get; set; }
    public int account_category { get; set; }
}

public class ExpensesResponse
{
    public List<Expense> Expense { get; set; }
}

public class Messages
{
    public string msgs { get; set; }
    public string errs { get; set; }
}

public class RootObject
{
    public List<ExpensesResponse> response { get; set; }
    public Messages messages { get; set; }
}

// deserialize the json to c# .net
var response = Newtonsoft.Json.JsonConvert.DeserializeObject<RootObject>(jsonData);

if (response != null)
{
          expenses = response.response;
}

我该怎么做才能纠正这个问题？

我已使用以下类型对数据进行反序列化。有一个空名称的属性，它应该有JsonPropertyAttribute。

public class Expense
{
    public string chart_of_accounts_id { get; set; }
    public string account_name { get; set; }
    public decimal amount { get; set; }
    public string entry_type { get; set; }
    public string business_id { get; set; }
    public int account_category { get; set; }
}

public class ExpensesResponse
{
    [JsonProperty(PropertyName = "")] 
    public ExpensesResponseContent Content { get; set; }
}

public class ExpensesResponseContent
{
    public List<List<Expense>> Expense { get; set; }

}

public class Messages
{
    public string msgs { get; set; }
    public string errs { get; set; }
}

public class RootObject
{
    public ExpensesResponse response { get; set; }
    public Messages messages { get; set; }
}

您可以使用Online JSON Viewer检查数据的结构。
