C#將數據本地持久化

有時候程式發生異常，用戶正在編輯數據突然系統就蹦了，為了避免用戶已經編輯的數據丟失，最好將用戶正在操作的數據進行本地持久化

        /// <summary>
        /// 將對象序列化後保存到文件中
        /// </summary>
        public static void SerializeToFile<T>(T obj, string dataFile) {
            using(FileStream fileStream = File.Create(dataFile)) {
                BinaryFormatter binSerializer = new BinaryFormatter();
                binSerializer.Serialize(fileStream, obj);
            }
        }

        /// <summary>
        /// 從文件中讀取數據並反序列化成對象
        /// </summary>
        public static T Deserialize<T>(string dataFile) {
            T obj = default(T);
            using(FileStream fileStream = File.OpenRead(dataFile)) {
                BinaryFormatter binDeserializer = new BinaryFormatter();
                obj = (T)binDeserializer.Deserialize(fileStream);
            }
            return obj;
        }

    Dictionary<string, object> transactionData = new Dictionary<string, object>() {
        { "Account","6226221601798333"},
        { "Name","張三"},
        { "TradeType","存款"},
        { "Amount",100.00d}
    };
    SerializeToFile(transactionData, "TD.txt");
    var currentData = Deserialize<Dictionary<string, object>>("TD.txt");
    foreach(var item in currentData) {
        Console.WriteLine("{0}-{1}",item.Key,item.Value);
    }
