我的程式為用戶提供了序列化某個串列的選項，該串列List<Position>ListPosition存盤來自位置類的資料。它確實序列化得很好，它看起來像下面這樣
{
"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
}
},
這些只是幾個例子。
給我帶來問題的一點是當我反序列化它時。
當我檢查轉換它的代碼位時 JsonConvert.DeserializeObject<List<Position>>(JsonString);，一切都很好，但是，當我將它與串列相等時，我試圖將資料轉儲到 AKA 序列化資料來自但為空的相同串列中，資料不會加載并且我留下了正確的結構，但沒有價值。
值未顯示
為了反序列化，我從另一個 Windows 表單呼叫以下方法：
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");
}
我真的很感激一些幫助。如果需要更多資訊，請務必在評論中提出要求。感謝您的時間。

uj5u.com熱心網友回復：
您的問題的原因是因為您將設定器定義為私有...
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; }
它應該是...
public static int MaxX { get; set; }
public static int MaxY { get; set; }
public int PosX { get; set; }
public int PosY { get; set; }
