C#

using System.Runtime.Serialization.Formatters.Binary;
using System.IO;

C#

private void Test()
{
    string file = "C:\\file";
    object ob1 = GetSomeObject();
    byte[] ba = ConvertObjectToByteArray(ob1);
    File.WriteAllBytes(file, ba);

    byte[] ba2 = File.ReadAllBytes(file);
    object ob2 = ConvertByteArrayToObject(ba);
}

C#

public static byte[] ConvertObjectToByteArray(object ob)
{
    BinaryFormatter bf = new BinaryFormatter();
    MemoryStream ms = new MemoryStream();
    bf.Serialize(ms, ob);
    return ms.ToArray();
}

public static object ConvertByteArrayToObject(byte[] ba)
{
    BinaryFormatter bf = new BinaryFormatter();
    Stream stream = new MemoryStream(ba);
    return bf.Deserialize(stream);
}

Update
Write string as binary file:

C#

string file = "C:\\file";
string string1 = "John|Gold Membership|RegisterDate=2013-12-13";
byte[] ba = Encoding.UTF8.GetBytes(string1);
File.WriteAllBytes(file,ba);

byte[] ba2 = File.ReadAllBytes(file);
string string2 = Encoding.UTF8.GetString(ba2);

MessageBox.Show(string2);

You can do it with BinaryFormatter class. Ya, there are many solutions fit to you question but more sophisticated serializing you can do it. See below.
