C# Object Binary Serialization

Question

I want to make a binary serialize of an object and the result to save it in a database.

Person person = new Person(); person.Name = "something";  MemoryStream memorystream = new MemoryStream(); BinaryFormatter bf = new BinaryFormatter(); bf.Serialize(memorystream, person); 

How can I transform memorystream in a string type to be saved in database, and after this to be able to deserialize the object?

Answer 1

What you're really asking for is a safe way of representing arbitrary binary data as text and then converting it back again. The fact that it stores a serialized object is irrelevant.

The answer is almost to use Base 64 (e.g. Convert.ToBase64String and Convert.FromBase64String). Do not use Encoding.UTF8.GetString or anything similar - your binary data is not encoded text data, and shouldn't be treated as such.

However, does your database not have a data type for binary data? Check for BLOB, IMAGE and BINARY types...
