这看起来像是一项作业，我们通常不做作业对于这里的人.但是，在我想出答案之前，那想法的手并没有出现在我身上，所以请以为自己很幸运，您完全得到了答复.
FWIW，您应该找到另一个小问题，因为他没有教您可以说是最重要的程序员技能-分析.

-------------

将字符串拆分为单词集合，然后使用LINQ计数给定单词的实例数.

This looks like a homework assignment, and we don''t generally do homework for people here. However, that thought hand''t occurred to me before I came up with the answer, so consider yourself lucky thata you got a response at all.
FWIW, you should find another isntructor because he''s not teaching you the arguably most important programmer skill - analysis.

-------------

Split the string into an collection of words, and then use LINQ to count the number of instances of a given word.

string mywordString = "around the rugged rock the ragged rascal ran";
string findWord = "the";

// at this point, you probably want to remove everything that''s not a 
// space or alhanumeric character. You can probably come up eith a 
// regex object for that.

List<string> words = new List<string>();
words.Add(words.ToLower().Split(" "));
findWord = findWord.ToLower();

int count = (from word in words 
             where word == findWord 
             select word).Count();

您可能需要稍作调整，但是它提供了如何解决问题的要点.
