how to give exception handling for json string if an array found instead of object usinc C#

Question

I am having a json text file as :

[
    { 
        "productId":"17213812",
        "returnPolicies": {
            "user":"Regular Guest"
        }
    },
    {
        "productId":"17813832",
        "returnPolicies":[]
    }
]

and I am getting error for returnPolicies since it has different properties. But I want only returnpoliciesuser so If i use e.returnpolicies.user it is showing error for second array.. Anyone knows how to skip "returnPolicies":[] and search only e.returnpolicies.user("returnPolicies":{"user":"Regular Guest"}) ?

The problem is not that they have different properties but that one is an object and the other an array. — NtFreX, Jul 12 '17 at 14:22
Please add the code that reads the JSON. Do you use `ChoJSONReader`? — Markus, Jul 12 '17 at 14:23
I don't know the `ChoJSONReader` but with other libraries you would need to change your json that both either use a list or an object. — NtFreX, Jul 12 '17 at 14:26

This is how you can do it.

using (var jr = new ChoJSONReader("sample6.json")
    .WithField("ProductId", jsonPath: "$.productId")
    .WithField("User", jsonPath: "$.returnPolicies.user")
    )
{
    foreach (var item in jr)
        Console.WriteLine(item.ProductId + " " + item.User);
}
