C# Groupby Linq and foreach

Something like this, perhaps?

    var groups = lst.GroupBy(x => x.state);

    foreach (var group in groups) 
    {
        using (var f = new StreamWriter(group.Key + ".txt"))
        {
            foreach (var item in group)
            {
                f.WriteLine(item.name);
                f.WriteLine(item.url);
            }
        }
    }
