自定義序列化對象c#.doc

自定義序列化對象很多時候，我們需要將對象序列化成字符串保存到內(nèi)存、磁盤或者 Page.ViewState 中?；诜N種原因，我們希望序列化結(jié)果盡可能小，盡可能簡單，即便用其他的方法(比如正則表達式)也能解析出數(shù)據(jù)。BinaryFormatter 的結(jié)果轉(zhuǎn)換成字符串(或者Base64)長度太大，而 XmlSerializer 對數(shù)據(jù)類型支持有限，顯然內(nèi)置的序列化引擎不足以滿足我們的需求，還是自己豐衣足食。下面的代碼可能還不完善，僅供參考，內(nèi)容比較簡單，不做詳述。/ / 序列化/ public static string SerializeObject(object o)char sep1 = |;char sep2 = ,;char sep3 = =;StringBuilder sb = new StringBuilder();FieldInfo fields = o.GetType().GetFields(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic);foreach (FieldInfo field in fields)object value = field.GetValue(o);if (value != null)if (field.FieldType.GetInterface(IDictionary) != null)foreach (object key in (value as IDictionary).Keys)sb.AppendFormat(0312, key, (value as IDictionary)key, sep2, sep3);if (sbsb.Length - 1 = sep2) sb.Remove(sb.Length - 1, 1);else if (field.FieldType.GetInterface(IList) != null)foreach (object v in (value as IList)sb.AppendFormat(01, v, sep2);if (sbsb.Length - 1 = sep2) sb.Remove(sb.Length - 1, 1);else if (field.FieldType = typeof(Boolean)sb.Append(bool)value ?
