是否可以制作一个采用 Dictionary<TKey, IEnumerable<T>> 的方法？

Question

是否可以创建一个方法，该方法采用具有泛型类型键和泛型 IEnumerable 值的字典？比如

private static bool AreDictionariesOfObjectAndListEqual<TKey, IEnumerable<T>>(Dictionary<TKey, IEnumerable<T>> dict1, Dictionary<TKey, IEnumerable<T>> dict2)
{
    var dict1String = string.Join(",",
                dict1.OrderBy(kv => kv.Key).Select(kv => kv.Key + ":" + string.Join("|", kv.Value.OrderBy(v => v))));
    var dict2String = string.Join(",",
                dict2.OrderBy(kv => kv.Key).Select(kv => kv.Key + ":" + string.Join("|", kv.Value.OrderBy(v => v))));

    return dict1String.Equals(dict2String);
}

Answer 1

你可以改用这样的东西：

private static bool AreDictionariesOfObjectAndListEqual<TKey, TValue>(Dictionary<TKey, IEnumerable<TValue>> dict1, Dictionary<TKey, IEnumerable<TValue>> dict2)
{
    var dict1String = string.Join(",",
                dict1.OrderBy(kv => kv.Key).Select(kv => kv.Key + ":" + string.Join("|", kv.Value.OrderBy(v => v))));
    var dict2String = string.Join(",",
                dict2.OrderBy(kv => kv.Key).Select(kv => kv.Key + ":" + string.Join("|", kv.Value.OrderBy(v => v))));

    return dict1String.Equals(dict2String);
}
