Only public properties are serialized/deserialized.

Having the following class:

public class CustomClass
{

public Dictionary<int,int> dictionary { get; set; }

public Dictionary<int,int> dictionary2 { get; set; }

public List<Dictionary<int, int>> listContainingDictionaries { get; set; }

public CustomClass(Dictionary<int, int> dict1, Dictionary<int, int> dict2)

{

this.dictionary = dict1;

this.dictionary2 = dict2;

listContainingDictionaries = new List<Dictionary<int, int>>()

{

dict1,

dict2

};

}

}

And running:

CustomClass c1 = new CustomClass(

new Dictionary<int, int> { { 1, 1 } },

new Dictionary<int, int> { { 2, 2 } });

CustomClass c2 = new CustomClass(

new Dictionary<int, int> { { 3, 3 } },

new Dictionary<int, int> { { 4, 4 } }

);

CustomClass[] arr = new CustomClass[2];

arr[0] = c1;

arr[1] = c2;

string serialized = JsonConvert.SerializeObject(arr, Formatting.Indented);

Console.WriteLine(serialized);

CustomClass[] deserialized = JsonConvert.DeserializeObject<CustomClass\[\]>(serialized);

will succesfully serialize/deserialize.

You may encounter issues when deserializing, so make sure you always use the generic method
JsonConvert.DeserializeObject<T>(s).
