Question

I have a sample xml file that looks like this:

<Books>
   <Category Genre="Fiction" BookName="book_name" BookPrice="book_price_in_$" />
   <Category Genre="Fiction" BookName="book_name" BookPrice="book_price_in_$" />
   <Category Genre="NonFiction" BookName="book_name" BookPrice="book_price_in_$" />
   <Category Genre="Children" BookName="book_name" BookPrice="book_price_in_$" />
</Books>  

I need to collect all book names and book prices and pass to some other method. Right now, i get all book names and book prices seperately into two different List<string> using the following command:

List<string>BookNameList = root.Elements("Category").Select(x => (string)x.Attribute("BookName")).ToList();
List<string>BookPriceList = root.Elements("Category").Select(x => (string)x.Attribute("BookPrice")).ToList();

I create a text file and send this back to the calling function (stroing these results in a text file is a requirement, the text file has two fields bookname and bookprice).

To write to text file is use following code:

for(int i = 0; i < BookNameList.Count; i++)
{
   //write BookNameList[i] to file
   // Write BookPriceList[i] to file
}

I somehow dont feel good about this approach. suppose due to any reason both lists of not same size. Right now i do not take that into account and i feel using foreach is much more efficient (I maybe wrong). Is it possible to read both the entries into a datastructure (having two attributes name and price) from LINQ? then i can easily iterate over the list of that datastructure with foreach.

I am using C# for programming.

Thanks,

[Edit]: Thanks everyone for the super quick responses, i choose the first answer which I saw.

Selecting:

var books = root.Elements("Category").Select(x => new {
    Name = (string)x.Attribute("BookName"), 
    Price = (string)x.Attribute("BookPrice")
}).ToList();

Looping:

foreach (var book in books)
{
    // do something with
    // book.Name
    // book.Price
}
