How to search through a custom structure list (C#) containing a string and byte?

I am trying to search through a list that contains a structure:

struct Item
{
    public string Name;
    public Byte[] Data;
}
static List<Item> Items = new List<item>();

Each time I receive the data, bytes change and have to be updated. Is there a way to search for the item that has to be updated, without for each loop?

Also, database is too slow for this - it has to happen in memory (list shouldn't exceed 1MiB)

Thanks

Went with dictionary, as suggested by Matthew Watson in the first reply.

static Dictionary<string, Byte[]> Items = new Dictionary<string, Byte[]>();

And updating the list with

Items[currentItem] = GetByteFromData(data);
//and
Items.Remove(currentItem);

Thanks everyone

Linq?

var targetItem = items.First ( x => x.Name == targetValue);

Not sure it is faster than a foreach though. Might be of interest that, unless it has changed recently, for loops are faster than foreach loops.
