JSON Serialization & Deserialization in c#

 Serialization:

Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file.

JSON Serialization:

JSON serialization serializes the public properties of an object into a string, byte array, or stream.

 public static string SerializeObject(object obj)

        {

            string jsonString = null;

            DataContractJsonSerializer serializer = null;

            MemoryStream memorystream = null;

            try

            {

                serializer = new DataContractJsonSerializer(obj.GetType());

                memorystream = new MemoryStream();

                serializer.WriteObject(memorystream, obj);

                jsonString = Encoding.UTF8.GetString(memorystream.ToArray());

            }

            catch

            {

                throw;

            }

            finally

            {

                if (memorystream != null)

                {

                    memorystream.Close();

                    memorystream.Dispose();

                }

            }

            return jsonString;

        }



JSON Deserialization:

It is used to deserialize a JSON string back to an object.

Below is a  generic method that accepts a JSON string and returns an object back.



private static T DeSerializeObject<T>(string jsonString)

        {

            T obj = default(T);

            DataContractJsonSerializer serializer = null;

            MemoryStream memorystream = null;

            try

            {

                serializer = new DataContractJsonSerializer(typeof(T));

                memorystream = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));

                obj = (T)serializer.ReadObject(memorystream);

            }

            finally

            {

                if (memorystream != null)

                {

                    memorystream.Close();

                    memorystream.Dispose();

                }

            }

            return obj;

        }
