我正在嘗試使用 C# 和 JSON.NET 將數(shù)據(jù)寫入 json 文件，參考此處建議的已接受答案（How to write a JSON file in C#?）。當(dāng)我運行下面的代碼時，我沒有收到任何錯誤消息，而且數(shù)據(jù)也沒有寫入 json 文件。從功能上講，我想要實現(xiàn)的是創(chuàng)建一個 json 文件，該文件存儲執(zhí)行 Nunit 測試時完成的操作的時間我已嘗試實施此處建議的解決方案（Deserializing JSON data to C# using JSON.NET）但它沒有解決我的問題public static class ActionTimeHelper{private static readonly string _actionTimeLogFileName = "ActionTimeLog_" + string.Format("{0:yyyy_MM_dd_hhmmss}", DateTime.Now);[ThreadStatic] private static FileStream _fileStream = null;[ThreadStatic] private static StreamWriter _actionStreamWriter = null;[ThreadStatic] private static JsonWriter _jsonWriter = null;[ThreadStatic] private static List<ActionTimeInfo> actionList = new List<ActionTimeInfo>();public static void CreateActionTimeLogFile(string logPath, string testName){    string dir = logPath + testName + @"\";    if (!Directory.Exists(dir))    {        Directory.CreateDirectory(dir);    }    _fileStream = File.Open(dir + _actionTimeLogFileName + ".json", FileMode.CreateNew);    _actionStreamWriter = new StreamWriter(_fileStream);    _jsonWriter = new JsonTextWriter(_actionStreamWriter);    _jsonWriter.Formatting = Formatting.Indented;    JsonSerializer serializer = new JsonSerializer();    serializer.Serialize(_jsonWriter, actionList.ToArray().ToString());    //var jarray = JsonConvert.DeserializeObject<List<ActionTimeInfo>>(actionList.ToArray().ToString());}public static void StartActionTime(string actionName){    actionList.Add(new ActionTimeInfo()    {        ActionName = actionName,        StartTime = DateTime.Now    });}public static void EndActionTime(string actionName){    ActionTimeInfo endAction = actionList.Find(actionInfo => actionInfo.ActionName.Equals(actionName));    endAction.EndTime = DateTime.Now;    endAction.ExecutionTime = endAction.EndTime.Subtract(endAction.StartTime);}}public class ActionTimeInfo{public string ActionName { get; set; }public DateTime StartTime { get; set; }public DateTime EndTime { get; set; }public TimeSpan ExecutionTime { get; set; }}
