求：java代码段翻译成c#（代码段如下）

Map<Integer, Integer> wordlist = doc.getWordList();
Iterator it = wordlist.entrySet().iterator();
while(it.hasNext()){
Map.Entry<Integer, Integer> entry = (Map.Entry<Integer, Integer>)it.next();
int wordID = entry.getKey();
int wordFreq = entry.getValue();
WordDocumentBean wdb = new WordDocumentBean(wordID, docID, wordFreq);

if(words.containsKey(wordID)){
words.get(wordID).add(wdb);
}
else{
List<WordDocumentBean> wdbListTemp = new LinkedList<WordDocumentBean>();
wdbListTemp.add(wdb);
words.put(wordID, wdbListTemp);
}
} --------------------编程问答-------------------- C# 使用Dictionary(TKey, TValue) 保存
遍历Dictionary<int, int> dict = new Dictionary<int, int>();
            foreach( KeyValuePair<int,int> entry in dict)
            {
            }

补充：.NET技术 ,  C#
