比较两个对象列表，返回匹配百分比c#

我正在寻找比较两个对象列表;掌握语料库中的语言。参考列表是由一个txt文件构建的。语料库也一样。

list Ref/list Corpus

    public Canagram(string anagram, int frequency,int percentage)
    {
        anagram = Anagram;         // exemple "a"
        frequency = Frequency;     // how many "a" in the txt 
        percentage = Percentage;   // what's the percentage compared to the other anagram
    }

目标是用百分比匹配每个列表上的每个字谜，并返回这两个列表之间匹配的全局百分比。

    public static int percentage(List<Canagram> reference, List<Canagram> corpus)
    {
        //don"t know how to compare this two list properly and return % match
        return (int) percentage of match;
    }

谢谢!

int cnt = reference.Count;
int matches = 0;
foreach (var phrase in reference)
{
if (corpus.Contains(phrase))
    matches++
}
double percent = (double)matches / (double)cnt;
