I want to convert this Json to list in c#.

Here's my JSON string and class

{"Headers":[{"KeyValue":"Hello AA"},{"KeyValue":"Hello BB"}],"Footers":[{"KeyValue":"Wifi Password : 11112222"}]}

public class Template
    {
        public List<HeaderInfo> Headers { get; set; }

        public List<FooterInfo> Footers { get; set; }
    }
    public class HeaderInfo
    {
        public string KeyValue { get;set; }
    }
    public class FooterInfo
    {
        public string KeyValue { get; set; }
    }

When I try convert it , it shows this problem:

Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type System.Collections.Generic.List<DXClass.Model.Template> 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) 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 'Headers', line 1, position 11.'

CodePudding user response：

Your JSON string is not a list but a single object. When you'd call JsonConvert.DeserializeObject<Template> the deserialization will succeed.

If you expect it to be a list, the JSON would look like this:

[{"Headers":[{"KeyValue":"Hello AA"},{"KeyValue":"Hello BB"}],"Footers":[{"KeyValue":"Wifi Password : 11112222"}]}]

CodePudding user response：

you are doing it incorrectly, your equivalent of JSON is Template object, not the List<Template>. It should be like this Template template = JsonConvert.DeserializeObject<Template>(inoutJson);
