Savu\ing the properties of a class?? 1

[Norviking]

I made a new class with lots of data. I now want to save this class data to a file. How should I "attack" this problem?? Do I have to write each and every property data of the class to a file, or can I save the hole class in go??

What is the best way to save a file, for security reasons?? I dont want a text file.

Plz help...

What you are trying to do is called serialization and you can find it very easily in MSDN online.
Basically, you mark your class with the [Serializable] attribute and then use something like this:

MyObject obj = new MyObject();
IFormatter formatter = new BinaryFormatter();
Stream stream = new FileStream("MyFile.bin", FileMode.Create, FileAccess.Write, FileShare.None);
formatter.Serialize(stream, obj);
stream.Close();

There are some other formatters available, including an XML one.

If you want a safer way, you can use crypted streams to write data. .NET framework supports different encrypting methods, both symmetric and asymmetric, like RSA for example.
