Answer 1

you can create an extension method:

public static class DictionaryExtensions
{
    public static void RemoveAll(this IDictionary dict, 
        Func predicate)
    {
        var keys = dict.Keys.Where(k => predicate(dict[k])).ToList();
        foreach (var key in keys)
        {
            dict.Remove(key);
        }
    }
}

...

dictionary.RemoveAll(x => x.Member == foo);
