C＃：循环或数组

Question

我有这样的代码为C＃

var wordCounts1 = myInterface.GetWordCounts(new[] { 
"one", "one", "two", "three", "three",}); 

预期的输出应该是：

{"one", 2}, {"two", 1}, {"three",2} 

我应该怎么用得到这个输出回路或数组？

Answer 1

分组由字应努力

new[] { "one", "one", "two", "three", "three" } 
    .GroupBy(x => x) 
    .Select(x => new 
     { 
      Word = x.Key, 
      Count = x.Count() 
     });
