c#中JSON与Class的转换

c#中JSON与Class的转换,包括序列化的库

    public class SerializableUtility
    {
        public static MemoryStream Serialize(object _obj)
        {
            BinaryFormatter formater = new BinaryFormatter();
            MemoryStream ms = new MemoryStream();
            formater.Serialize(ms, _obj);

            return ms;
        }

        public static T DeSerialize<T>(byte[] _byte)
        {
            T t = default(T);

            BinaryFormatter formater = new BinaryFormatter();
            MemoryStream ms = new MemoryStream(_byte);
            t = (T)formater.Deserialize(ms);

            return t;
        }
    }

    public class JSONUtility
    {
        public static string Serialize<T>(T t)
        {
            if (t == null) return string.Empty;
            JavaScriptSerializer Serializer = new JavaScriptSerializer();
            return Serializer.Serialize(t);
        }

        public static List<T> DeSerializeToList<T>(string JsonStr)
        {
            List<T> objs = new List<T>();
            try
            {
                if (!string.IsNullOrEmpty(JsonStr))
                {
                    JavaScriptSerializer Serializer = new JavaScriptSerializer();
                    objs = Serializer.Deserialize<List<T>>(JsonStr);
                }
            }
            catch (System.Exception ex)
            {
                objs = null;
            }
            return objs;
        }

        public static T DeSerialize<T>(string json)
        {
            T obj = Activator.CreateInstance<T>();
            using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json)))
            {
                System.Runtime.Serialization.Json.DataContractJsonSerializer serializer = new System.Runtime.Serialization.Json.DataContractJsonSerializer(obj.GetType());
                return (T)serializer.ReadObject(ms);
            }
        }

    }

使用：

    [Serializable]
    public class Permission
    {
        public int ModuleID;
        public string ModulePermission;
    }

string JsonPermisstion="[{\"ModuleID\":110,\"ModulePermission\":\"read\"},{\"ModuleID\":120,\"ModulePermission\":\"read\"},{\"ModuleID\":210,\"ModulePermission\":\"denied\"},{\"ModuleID\":220,\"ModulePermission\":\"denied\"}]";

List<Permission> PermissionList = JSONUtility.DeSerializeToList<Permission>(JsonPermisstion);

string PermissionStr=JSONUtility.Serialize<List<Permission>>(PermissionList)
