Convert JSON string to object C#

I have JSON string results as follows. enter image description here

In this response Sometimes sizeKey and sizeName properties are returned as a string. But sometimes both properties are returns inside an array as follows enter image description here

I am using following code to convert it to object

var assets = jObject["assets"].Children().ToList();
            foreach (var item in assets)
            {
                decorationAssets.Add(item.ToObject<AEDecorationAssets>());
            }

And my AEDecorationAssets class is as follows.

public class AEDecorationAssets
{
    public string Id { get; set; }
    public string Url { get; set; }
    public string[] Colors { get; set; }
    public string FontKey { get; set; }
    public string SizeKey { get; set; }
    public string ViewKey { get; set; }
    public string FontName { get; set; }
    public int Rotation { get; set; }
    public string SizeName { get; set; }
    public string TextValue { get; set; }
    public string EntityType { get; set; }
    public string LocationCode { get; set; }
    public string LocationName { get; set; }
    public string TextEffectKey { get; set; }
    public string TextEffectName { get; set; }
    public string DecorationMethod { get; set; }
    public string NumDecorationColors { get; set; }
}

At the time when "sizeKey" is an array, the above code gives an error. How can I resolve this issue? Is there any JSON property we can use to resolve it?

Simply get json result for which you want to create c# object and then you can valid json response from https://jsonlint.com/ and then you can create c# object of any type json response which you want through http://json2csharp.com. And after get c# object of your json response you only need to deserialization of your json response to c# object which you have created. which will return you expected result.

If a JSON type is sometime an array, and sometimes a string, you can't really map it simply to a .NET type, as there is none that supports this behavior.

So first you need a datatype that can store this, like and string[] or List<string>.

It could be that JsonConvert will solve this automatically, but otherwise you'll need to write a custom ContractResolver or JsonConverter. Here you can detect if the source property is a string or array. If it's an array, you can use the default deserialization. If it is a string, you need to convert it to an array with a single value.

One way you can do it is by making your SizeKey type an object (i.e. public object SizeKey { get; set; }), then you can switch/case on item.ToObject<AEDecorationAssets>().SizeKey.GetType() to figure out how to handle it (i.e. if String do this, if JArray do that), etc.
