Question

我有代码来计算文件中重复的单词

这是

static void Main()
    {
        StreamReader f = new StreamReader(@"d:\C#\text.txt");
        string s = f.ReadToEnd();
        char[] separators = { };//here is symbols
        List<string> words = new List<string>(s.Split(separators));
        Dictionary<string, int> map = new Dictionary<string, int>();
        foreach (string w in words) 
            if (map.ContainsKey(w)) map[w]++; else map[w] = 1;
        foreach (string w in map.Keys)
            Console.WriteLine("{0}\t{l}", w.map[w]);
    }

但是在这一行Console.WriteLine("{0}\t{l}", w.map[w]);中我有这个错误。

错误CS1061'string'不包含'map'的定义，并且没有可以找到接受类型'string'的第一个参数的扩展方法'map'

我如何解决此错误？

如果我得到你想要的东西，这将有所帮助：

List<string> words = new List<string>() { "c#", "html", "web service", "c#", "c#" };

Dictionary<string, int> map = new Dictionary<string, int>();

foreach (string w in words)
{
    if (map.ContainsKey(w))
    {
        map[w] = map[w]+1;
    }
    else
    {
        map[w] = 1;
    }
}

//to iterate through Dictionary<string, int> use this instead
foreach (KeyValuePair<string, int> entry in map)
{
    Console.WriteLine($"{entry.Key}\t{entry.Value}");
}
