I tried the following code but am not able to parse json sting. When I am parsing I am getting this error:
我尝试了以下代码,但无法解析json sting。当我解析时,我收到此错误:
Cannot deserialize the current JSON object (e.g. {“name”:“value”}) into type 'System.Collections.Generic.List`1
无法将当前JSON对象(例如{“name”:“value”})反序列化为类型'System.Collections.Generic.List`1

4 个解决方案
#1
Try to change hidden field value from
尝试更改隐藏的字段值
HiddenField1.Value = "{\"AlertDataList\":[{...}]}"
to
HiddenField1.Value = "[{\"AlertDataList\":[{...}]}]"
#2
You're deserializing to a List<alertMain>
, yet your JSON contains simply one alertMain
.
您正在反序列化为List
Try:
alertMain json = JsonConvert.DeserializeObject<alertMain>((HiddenField1.Value).ToString());

Answer from my comment.
回答我的评论。
You are trying to convert List<alertMain>
. alertMain
already contains a list.
您正在尝试转换List
Try using just alertMain
since it is already containing the list of alerts.
尝试使用alertMain,因为它已经包含警报列表。
#4
You need to cast your json into List<IDictionary<string,string>>
this will should be work.
你需要将你的json转换为List
PFB code.
public void AlertTable()
{
var json = JsonConvert.DeserializeObject<RootObject>((HiddenField1.Value).ToString());
}
and you just create a one class like below:
你只需创建一个如下所示的类:
public class RootObject
{
public List<IDictionary<string, string>> AlertDataList { get; set; }
}
