将json字符串反序列化为对象数组，然后将其转换为Dictionary？

Question

This is the json string

[{"ProductIdentifier":"{test:'some data'}","validationCompleted":0}]

I am trying to deserialize an object into an object array which works fine but when i am trying to cast it back to an dictionary i am getting an exception can anyone please help me with this thank you.

    m_receiptsList is an object[] 
 m_receiptsList = JsonConvert.DeserializeObject<object[]>(pastJsonString,
                                                        new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All});
  for(int i=0; i<m_receiptsList.Length; i++)
{
    Dictionary<string, object> receiptItem = (Dictionary<string, object>)m_receiptsList[i]; 
 bool breceipt = receiptItem["validationCompleted"].Equals(0);
}

// exception while doing this saying cannot cast object m_receiptList[i] to dictionary.

If you want Json.NET to deserialize your JSON as an array of dictionaries, you need to tell it to do so:

        object[] m_receiptsList;
        m_receiptsList = JsonConvert.DeserializeObject<Dictionary<string, object>[]>(pastJsonString, new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All });

Incidentally, setting TypeNameHandling = TypeNameHandling.All isn't going to help you because your JSON sample has no type information. If it did, there would be a property "$type" at the beginning of your object(s).

Also, JSON.Net will convert a JSON integer into a long unless told otherwise, so you would need to do:

        foreach (IDictionary<string, object> dict in m_receiptsList)
        {
            bool breceipt = dict["validationCompleted"].Equals((long)0);
        }
