如何從文本中找到最多出現的單詞？

Question

我有一個數據庫字段，其中包含string值。 我正在尋找一種方式來找到前10名最大發生的話從外地

Answer 1

var result = 
    Regex.Matches(s, @"\b\w+\b").OfType<Match>() 
     .GroupBy(k => k.Value, (g, u) => new { Word = g, Count = u.Count() }) 
     .OrderBy(n => n.Count) 
     .Take(10); 

Answer 2

首先獲得所有來自外地的話：通過計數

IEnumerable<string> allWords = from entry in table 
           from word in entry.Field.Split(' ') 
           select word; 

然後將它們分組：

IEnumerable<string> result = from word in allWords 
          group word by word into grouped 
           let count = grouped.Count() 
           orderby count descending 
           select grouped.Key; 

獲得前10名成績：

result.Take(10); 

Answer 3

在這裏，您有數字一個簡單的例子：

class Program 
{ 
    static void Main(string[] args) 
    { 
     int[] nums = new int[] { 2, 3, 4, 5, 6, 1, 2, 3, 1, 1, 1, 7, 12, 451, 13, 
      46, 1, 1, 3, 2, 3, 4, 5, 3, 2, 4, 4, 5, 6, 6, 8, 9, 0}; 
     var numberGroups = 
      (from n in nums 
      group n by n into g 
      orderby g.Count() descending 
      select new { Number = g.Key, Count = g.Count() } 
      ).Take(10); 

     Console.ReadLine(); 
    } 
}
