Top 10 most used words in a text document

How will I do the count ? Then do a count of how many times each word appears.
If I have a list List<string> myList = new List<String>();
How do I count ?
myList.Add("The");
myList.Add("lazy");
myList.Add("Brown");
myList.Add("Fox");
myList.Add("was");
myList.Add("too");
myList.Add("lazy");
myList.Add("to");
myList.Add("jump");
myList.Add("over");
myList.Add("the");
myList.Add("brown");
myList.Add("dog");

Thx
