字计数器实现

有没有比下面的C字数类的暴力焦点实现更好的方法?

更新代码:对不起!

/// <summary>
/// A word counting class.
/// </summary>
public class WordCounter
{
    Dictionary<string, int> dictTest = new Dictionary<string, int> ();

    /// <summary>
    /// Enters a word and returns the current number of times that word was found.
    /// </summary>
    /// <param name="word">The word or string found.</param>
    /// <returns>Count of times Found() was called with provided word.</returns>
    public int Found ( string word )
    {
        int count = 1;
        return dictTest.TryGetValue ( word, out count ) ? ++dictTest[word] : dictTest[word] = 1;
    }
}
