It's easy to do something like this

foreach(Grade curr in arrList)
{
     myStreamWriter.Write(Grade.Name);
     myStreamWriter.Write(Grade.Score);
}

Is there an easy method to read/write all the Grade object?

Edit
====

Of course the example should have been curr.property
but I am looking for a way to write all the curr at once

Try to use different object serialization technique. Here are lists of MSDN articles.

I think using of this kind of serialization for custom purposes is rendered obsolete by the Data Contact.

Solution 1

Easy is a relative term. What are you trying to accomplish? Simply your code, improve performance?

You could make sure the objects are serializable then serialize them to some file stream, but the method you have is simple enough.

It's easy to do something like this

C#

foreach(Grade curr in arrList)
{
     myStreamWriter.Write(Grade.Name);
     myStreamWriter.Write(Grade.Score);
}

Is there an easy method to read/write all the Grade object?

The 2 easy looks contradicting. What are you really trying to say?

I am trying to write/read all the object, without carring of the properties.
Something like mySWriter.Write(grade1);

did you mean you need to get all the properties of an object?

Solution 2

Your attempt was a naive way. The best, most universal, easiest and non-intrusive way is using Data Contract.

Please see http://msdn.microsoft.com/en-us/library/ms733127.aspx[^].

Please also see my past answers where I advocate this wonderful approach and explain some important detail:
How can I utilize XML File streamwriter and reader in my form application?[^],
Creating property files...[^],
deseralize a json string array[^].
