LINQ query syntax with multiple statements

Can this method be rewritten using LINQ's query syntax?

public IEnumerable<Item> GetAllItems()
{
    return Tabs.SelectMany(tab =>
        {
            tab.Pick();
            return tab.Items;
        });
}

I cannot figure out where to place tab.Pick() method call.

No, query expressions in LINQ require each selection part etc to be a single expression, not multiple statements.

However, you could write a separate method:

public IEnumerable<Item> PickItems(Tab tab)
{
    tab.Pick();
    return tab.Items;
}

Then use:

var query = from tab in tabs
            from item in PickItems(tab)
            select item.Name;

(Or whatever you want to do.)
