Как правильно проанализировать json в C# [закрыто] ⇐ C#

[Anonymous]

У меня есть следующий json в файле, который я назвал dtmdiom.json :
{"columns":"1"
,"gapx":"2"
,"gapy":"2"
,"iomask":"0xffff"
,"name":"5069-IB16F"
,"offcolor":"0xff000000"
,"oncolor":"0xff00ff00"
,"shapewidth":"16"
,"shapeheight":"16"
,"showtags":"true"}
< /code>
Моя логика в c#: < /p>
public void AddControl() {
//Look for the parent panel
Log.Info($"CWD: {System.IO.Directory.GetCurrentDirectory()}");
IUANode iuaNode = iuanGetSpecificOwnerType(Owner, Owner.GetType());
Log.Info($"Checking for {mstrFileSpec}");
if (File.Exists(mstrFileSpec)) {
//Read configuration from file
Log.Info($"Found: {mstrFileSpec}, reading...");
using FileStream fs = new FileStream(mstrFileSpec
, FileMode.Open
, FileAccess.Read);
using StreamReader rdr = new StreamReader(fs);
string strContent = rdr.ReadToEnd().Trim();
Log.Info(strContent);
byte[] arybytContent = System.Text.Encoding.ASCII.GetBytes(strContent);
if (arybytContent != null) {

JSObject json = JsonSerializer.Deserialize(arybytContent);
Log.Info(json.ToString());
}
}
}
< /code>
Это не удается со следующей сообщением об ошибке: < /p>
FTOptix.NetLogic;Warning;2;Error invoking method 'AddControl' in NetLogic Root/Objects/NewHMIProject/UI/MainWindow/scr1/pnlAll/hloColumns/Panel1/dtmDigital_IO_Module:

Вышеуказанное все относится к строке, которая считывает: < /p>
JSObject json = JsonSerializer.Deserialize(arybytContent);
< /code>
Может ли кто-нибудь помочь? class clsDIOM {
[JsonPropertyName("columns")]
public String Colunns { get; set; }

[JsonPropertyName("gapx")]
public String GapX { get; set; }

[JsonPropertyName("gapy")]
public String GapY { get; set; }

[JsonPropertyName("iomask")]
public String IOmask { get; set; }

[JsonPropertyName("name")]
public String Name { get; set; }

[JsonPropertyName("offcolor")]
public String OffColor { get; set; }

[JsonPropertyName("oncolor")]
public String OnColor { get; set; }

[JsonPropertyName("shapewidth")]
public String ShapeWidth { get; set; }

[JsonPropertyName("shapeheight")]
public String ShapeHeight { get; set; }

[JsonPropertyName("showtags")]
public String ShowTags { get; set; }
}
< /code>
Измененная логика на: < /p>
public async Task AddControl() {
// Log.Info($"52 Owner: {Owner.BrowseName}");
// NodeId nid = Owner.NodeId;
// var objPanel = InformationModel.Get(nid);
// if (objPanel != null) {
// Log.Info($"56 objPanel:[{objPanel}]");
// Log.Info($"57 objPanel.Width:[{objPanel.Width}]");
// Log.Info($"58 objPanel.Height:[{objPanel.Height}]");
// }
//Look for the parent panel
Log.Info($"CWD: {System.IO.Directory.GetCurrentDirectory()}");
IUANode iuaNode = iuanGetSpecificOwnerType(Owner, Owner.GetType());
Log.Info($"Checking for {mstrFileSpec}");
if (File.Exists(mstrFileSpec)) {
//Read configuration from file
Log.Info($"Found: {mstrFileSpec}, reading...");
var fileContents = File.ReadAllText(mstrFileSpec);
var json = JsonSerializer.Deserialize(fileContents);
Log.Info(json.ToString());
}
}

Когда я выполняю AddControl I Que Get:
