With LINQ:
var fooDict = foos.ToDictionary(x=>x.Name,x=>x.StreetAddress);
(and yes, fooDict is Dictionary<string, string>)
edit to show the pain in VS2005:
Dictionary<string, string> fooDict =
Program.ToDictionary<Foo, string, string>(foos,
delegate(Foo foo) { return foo.Name; },
delegate(Foo foo) { return foo.StreetAddress; });
where you have (in Program):
public static Dictionary<TKey, TValue> ToDictionary<TSource, TKey, TValue>(
IEnumerable<TSource> items,
Converter<TSource, TKey> keySelector,
Converter<TSource, TValue> valueSelector)
{
Dictionary<TKey, TValue> result = new Dictionary<TKey, TValue>();
foreach (TSource item in items)
{
result.Add(keySelector(item), valueSelector(item));
}
return result;
}
