抱歉，我的英语很少。

我想用字符串计算短语。

我的字符串在下面;

Lorem ipsum dolor 坐下来，奉献精神。法无 venenatis， lorem ipsum augue vel pellentesque sit amet ， lorem ipsum dolor egestas lacus， et ipsum dolor nulla。

我想在下面;

3x Lorem ipsum



2x 坐下来

Answer 1

首先，它不太清楚“重复的单词”是什么意思，但我猜你需要将逗号分隔的单词或短语列表分成单个单词，单独测试每个单词或单词。如果是这样的话：

string words = "I love red color. He loves red color. She love red kit. ";
myWordString = myWordString .Replace(" ", ",");
myWordString  = myWordString .Replace(".", "");

string[] words = s.Split(',');
foreach (string theWord in words)
{
    // now do something with them individually
}

使用词典

Dictionary<string, Int32> wordList= new Dictionary<string, Int32>();

然后一旦你得到单词字符串，循环你的字符串中的单词，并在每个循环中，你可以添加到字典，或增加计数

-- psuedo loop code from above 

if (wordList.ContainsKey(theWord)) {

    wordList[theWord] = wordList[theWord] + 1;

} else {

    wordList.Add(theWord, 1);

}

-- end psuedo loop code from above

依此类推。当你的循环完成后，列表中的所有单词......你可以像这样翻阅字典：

foreach(var pair in wordList)
{
    var key = pair.Key;
    var value = pair.Value;
}

如何使用LINQ？

var wordList = words.Split(new[] { " ", ".", "," }, StringSplitOptions.RemoveEmptyEntries)
                    .GroupBy(x => x)
                    .ToDictionary(g => g.Key, g => g.Count());
