Question

我尝试了以下代码，但无法解析json sting。什么时候我正在解析我收到此错误：

无法将当前JSON对象（例如{“name”：“value”}）反序列化为类型'System.Collections.Generic.List`1

   HiddenField1.Value = "{\"AlertDataList\":[{\"header\":\"YTD Noresp 04/01/2010 &#45; 01/31/2011 Created On 10/02/2013\",\"type\":\"High      \",\"NoResponse\":\"0\",\"NoResponsePct\":\"      0.00&#37;\",\"Response\":\"1\",\"ResponsePct\":\"    100.00&#37;\",\"All\":\"1\",\"accountperiodid\":\"11306\",\"navigateUrl\":\"windowpane://Insights.exe/HCI.Insights.Windows.Forms.Converted.FormFinalert…&responseType=NoResp&accountPeriodId=11306&alertType=High&hasResponses=All\",\"navigateResponsesUrl\":\"windowpane://Insights.exe/HCI.Insights.Windows.Forms.Converted.FormFinalert…responseType=NoResp&accountPeriodId=11306&alertType=High&hasResponses=Resp\",\"navigateNoResponsesUrl\":\"windowpane://Insights.exe/HCI.Insights.Windows.Forms.Converted.FormFinalert…D&responseType=NoResp&accountPeriodId=11306&alertType=High&hasResponses=No Resp\"},{\"header\":\"YTD Noresp 04/01/2010 &#45; 01/31/2011 Created On 10/02/2013\",\"type\":\"Medium\",\"NoResponse\":\"0\",\"NoResponsePct\":\"      0.00&#37;\",\"Response\":\"1\",\"ResponsePct\":\"    100.00&#37;\",\"All\":\"1\",\"accountperiodid\":\"11306\",\"navigateUrl\":\"windowpane://Insights.exe/HCI.Insights.Windows.Forms.Converted.FormFinalert…esponseType=NoResp&accountPeriodId=11306&alertType=Medium&hasResponses=All\",\"navigateResponsesUrl\":\"windowpane://Insights.exe/HCI.Insights.Windows.Forms.Converted.FormFinalert…sponseType=NoResp&accountPeriodId=11306&alertType=Medium&hasResponses=Resp\",\"navigateNoResponsesUrl\":\"windowpane://Insights.exe/HCI.Insights.Windows.Forms.Converted.FormFinalert…responseType=NoResp&accountPeriodId=11306&alertType=Medium&hasResponses=No Resp\"},{\"header\":\"YTD Noresp 04/01/2010 &#45; 01/31/2011 Created On 10/02/2013\",\"type\":\"All\",\"NoResponse\":\"0\",\"NoResponsePct\":\"      0.00&#37;\",\"Response\":\"2\",\"ResponsePct\":\"    100.00&#37;\",\"All\":\"2\",\"accountperiodid\":\"11306\",\"navigateUrl\":\"windowpane://Insights.exe/HCI.Insights.Windows.Forms.Converted.FormFinalert…D&responseType=NoResp&accountPeriodId=11306&alertType=All&hasResponses=All\",\"navigateResponsesUrl\":\"windowpane://Insights.exe/HCI.Insights.Windows.Forms.Converted.FormFinalert…&responseType=NoResp&accountPeriodId=11306&alertType=All&hasResponses=Resp\",\"navigateNoResponsesUrl\":\"windowpane://Insights.exe/HCI.Insights.Windows.Forms.Converted.FormFinalert…TD&responseType=NoResp&accountPeriodId=11306&alertType=All&hasResponses=No Resp\"}]}"


    public void AlertTable()
    {           
        List<alertMain> json = JsonConvert.DeserializeObject <List<alertMain>>((HiddenField1.Value).ToString());          

    }

public class alert

    [JsonProperty("header")]
    public string header { get; set; }

    [JsonProperty("type")]
    public string type { get; set; }

    [JsonProperty("NoResponse")]
    public string NoResponse { get; set; }

    [JsonProperty("NoResponsePct")]
    public string NoResponsePct { get; set; }

    [JsonProperty("Response")]
    public string Response { get; set; }

    [JsonProperty("ResponsePct")]
    public string ResponsePct { get; set; }

    [JsonProperty("All")]
    public string All { get; set; }

    [JsonProperty("accountperiodid")]
    public string accountperiodid { get; set; }

    public string navigateUrl { get; set; }

    [JsonProperty("navigateResponsesUrl")]
    public string navigateResponsesUrl { get; set; }

    public string navigateNoResponsesUrl { get; set; }        
}

public class alertMain
{
    [JsonProperty("AlertDataList")]
    public List<alert> AlertDataList { get; set; }
}

Answer 1

尝试从

更改隐藏字段值

HiddenField1.Value = "{\"AlertDataList\":[{...}]}"

到

HiddenField1.Value = "[{\"AlertDataList\":[{...}]}]"

Answer 2

您要反序列化为List<alertMain>，但您的JSON只包含一个alertMain。

尝试：

alertMain json = JsonConvert.DeserializeObject<alertMain>((HiddenField1.Value).ToString());

Answer 3

从我的评论中回答。

您正在尝试转换List<alertMain>。 alertMain已包含一个列表。

请尝试仅使用alertMain，因为它已包含警报列表。

Answer 4

你需要将你的json转换为modal这应该可行。

PFB代码。

List<IDictionary<string,string>>

你只需创建一个如下所示的类：

public void AlertTable()
{
            var json = JsonConvert.DeserializeObject<RootObject>((HiddenField1.Value).ToString());

}

如何在c＃中解析JSON字符串获取错误无法反序列化当前的JSON对象（例如{“name”：“value”}）
