how to serialize class to database instead of file system c#

Question

we can easily serialize class to flat file but if i want to serialize class to database then how could i do it and if it is possible then how can i deserialize data from db to c

Answer 1

Like other said at already, you can use binary serialization to get the Byte[] array in a memory stream and then create a column in database of type Blob / image to store the the byte array.

Then while reading back, you just read the value of the column in the stream back by using technique called deserialization

Serialization

  BinaryFormatter bf = new BinaryFormatter();

        List _list = QueryFilterDetails.ToList();

        using (MemoryStream ms = new MemoryStream())
        {
            bf.Serialize(ms, _list);
            return ms.GetBuffer();
        }

Deserialization

  private void DeSerilizeQueryFilters(byte[] items)
    {
        BinaryFormatter bf = new BinaryFormatter();

        List _list = new List();

        try
        {
            using (MemoryStream ms = new MemoryStream())
            {
                ms.Write(items, 0, items.Length);
                ms.Position = 0;

                _list = bf.Deserialize(ms) as List;
            }

            foreach (SearchFilterDetails mobj in _list)
            {
                QueryFilterDetails.Add(mobj);
            }
        }
        catch (Exception ex)
        {
        }
    }
