public string Name
{
get { return _name; }
set { _name = value; }
}

public Item ()
{

}

protected Item (SerializationInfo info, StreamingContext context)
{
_name = (string)info.GetValue("_name", typeof(string));
}

public void GetObjectData(SerializationInfo info, StreamingContext context)
{
info.AddValue("_name", _name, typeof(string));
}
}

For data serialization, you can specify the desired name and the desired type

info.AddValue("_name", _name, typeof(string));

When the data is deserialized, you will be able to read the desired type

_name = (string)info.GetValue("_name", typeof(string));

Serialization surrogates (Implementing ISerializationSurrogate)

Implements a serialization surrogate selector that allows one object to perform serialization and
deserialization of another

As well allows to properly serialize or deserialize a class that is not itself serializable

Implement ISerializationSurrogate interface

public class ItemSurrogate : ISerializationSurrogate
{
public void GetObjectData(object obj, SerializationInfo info, StreamingContext context)
{
var item = (Item)obj;
info.AddValue("_name", item.Name);
}

public object SetObjectData(object obj, SerializationInfo info, StreamingContext context,
ISurrogateSelector selector)
{
var item = (Item)obj;
item.Name = (string)info.GetValue("_name", typeof(string));
return item;
}
}
