C# .NET 3.5 对象序列化字符串

支持任何形式的数据结构的对象，可用于将对象保存成文件，或者两个进程之间传参（当然，还有xml、json等方案）

工具类：

        {
            try
            {
                IFormatter formatter = new BinaryFormatter();
                MemoryStream stream = new MemoryStream();
                formatter.Serialize(stream, obj);
                stream.Position = 0;
                byte[] buffer = new byte[stream.Length];
                stream.Read(buffer, 0, buffer.Length);
                stream.Flush();
                stream.Close();
                return Convert.ToBase64String(buffer);
            }
            catch (Exception ex)
            {
                throw new Exception("序列化失败,原因:" + ex.Message);
            }

                obj = default(T);
                IFormatter formatter = new BinaryFormatter();
                byte[] buffer = Convert.FromBase64String(str);
                MemoryStream stream = new MemoryStream(buffer);
                obj = (T)formatter.Deserialize(stream);
                stream.Flush();
                stream.Close();
            }
            catch (Exception ex)
            {
                throw new Exception("反序列化失败,原因:" + ex.Message);
            }
            return obj;
        }

    }
}

 

示例：

            Dictionary<string, object> parent = new Dictionary<string, object>();
            parent["name"] = "张三";
            parent["age"] = "35";
            Dictionary<string, object> children = new Dictionary<string, object>();
            children["name"] = "张三儿";
            children["age"] = "7";
            parent["children"] = children;

            // 对象序列化成字符串
            string s = DataUtil.SerializeToBase64(parent);
            Console.WriteLine("序列化后结果: " + s);

            // 字符串反序列化成对象
            Dictionary<string, object> d = new Dictionary<string, object>();
            d = DataUtil.DesrializeFromBase64(d, s);
            Dictionary<string, object> cdr = (Dictionary<string, object>)d["children"];
            object childName = cdr["name"];
            Console.WriteLine("反序列化后取值: " + childName);

控制台打印结果：
