如何在Linq查询中获取Summ?

模型是:

public class Word
{
    public int Id { get; set; }
    public IList<UsedCount> UsedCount { get; set; }
}

public class UsedCount
{
    public int Id { get; set; }
    public string Key { get; set; }
    public int Value { get; set; }
}

有语言列表:

// Actually there are more then 3 langs used
List<string> langList = new List<string> { "en", "pl", "de" }; 

还有单词表

List<Word> words = new List<Words>();

我计算每个单词在每种语言中使用的次数。 我需要让所有的单词总共使用100次以上,不管使用哪种语言:

renewingIteration = Words.Where(p => (
    p.UsedCount.FirstOrDefault(count => count.Key == langList[0]).Value +
    p.UsedCount.FirstOrDefault(count => count.Key == langList[1]).Value +
    p.UsedCount.FirstOrDefault(count => count.Key == langList[2]).Value 
    //... and so on
    > 100)

如何使其更简单并避免编写langlist[0]、langlist[1]…手动?
