我编写了一个非常简单的"字数统计"程序,它读取文件并计算文件中每个单词的出现次数.这是代码的一部分:

class Alaki
{
    private static List<string> input = new List<string>();

    private static void exec(int threadcount)
    {
        ParallelOptions options = new ParallelOptions();
        options.MaxDegreeOfParallelism = threadcount;
        Parallel.ForEach(Partitioner.Create(0, input.Count),options, (range) =>
        {
            var dic = new Dictionary<string, List<int>>();
            for (int i = range.Item1; i < range.Item2; i++)
            {
                //make some delay!
                //for (int x = 0; x < 400000; x++) ;                    

                var tokens = input[i].Split();
                foreach (var token in tokens)
                {
                    if (!dic.ContainsKey(token))
                        dic[token] = new List<int>();
                    dic[token].Add(1);
                }
            }
        });

    } …
