My program gives the user the option to serialize a certain list List<Position>ListPosition that stores the data from the class Position. It does serialize pretty well and it sorta looks like the following
{
"PosZ": 0,
"PosX": 749,
"PosY": 208,
"Agent": {
"IsEdgeTree": false,
"ThisTreesCreator": null,
"Type": 0,
"Colour": "Green",
"Dimension": 25
}
},
{
"PosZ": 0,
"PosX": 724,
"PosY": 183,
"Agent": {
"IsEdgeTree": false,
"ThisTreesCreator": {
"IsEdgeTree": false,
"Position": {
"PosZ": 0,
"PosX": 749,
"PosY": 208
},
"ThisTreesCreator": null,
"Type": 0,
"Colour": "Green",
"Dimension": 25
},
"Type": 0,
"Colour": "Green",
"Dimension": 25
}
},
These are just a few examples.
The bit that is giving me problems is when I deserialize it.
When I inspect the bit of code that converts it JsonConvert.DeserializeObject<List<Position>>(JsonString);, everything reads fine but, when I equal it to the List I am trying to dump the data to AKA the same list the serialized data comes from but empty, the data doesn't load and I'm left with the correct structure but no values.
To Deserialize, I call the following method from another Windows Forms:
public static void Deserialize()
{
if (Directory.Exists("Serialized"))
{
var FileName = "Serialized/PositionsSerialized_4.json";
var JsonString = File.ReadAllText(FileName);
ListPositions = JsonConvert.DeserializeObject<List<Position>>(JsonString);
}
else
MessageBox.Show("There's no directory");
}
I would really appreciate some help. If more information is needed, be sure to request it in the comments. Thank you for your time.

CodePudding user response：
The reason of your problem is because you defined setters as private...
public static int MaxX { get; private set; }
public static int MaxY { get; private set; }
public int PosX { get; private set; }
public int PosY { get; private set; }
it should be...
public static int MaxX { get; set; }
public static int MaxY { get; set; }
public int PosX { get; set; }
public int PosY { get; set; }
