How to programmatically set "Enable field level fallback" field on a Template Field item?

Question

I'm using sitecore 8.2. I have a list of the Template Field items where I need to check the "Enable field level fallback" field programmatically.

So, something like that:

foreach (var item in ListOfItems)
{
    item.Fields["Enablefieldlevelfallback"].Value = "1";
    break;
}

Any help would be appreciated.

Well, you don't provide much of a context. But API wise, it would come out like this:

        foreach (Item item in ListOfItems)
        {
            item.Editing.BeginEdit();
            item.Fields[FieldIDs.EnableLanguageFallback].Value = "1";
            item.Editing.EndEdit();
        }

For the Shared version of Language Fallback, change the constant.

        foreach (Item item in ListOfItems)
        {
            item.Editing.BeginEdit();
            item.Fields[FieldIDs.EnableSharedLanguageFallback].Value = "1";
            item.Editing.EndEdit();
        }
