C#基础课程之五集合（HashTable,Dictionary）

HashTable例子：
 #region HashTable
            #region Add
            Hashtable hashTable = new Hashtable();
            Hashtable hashTableNews = new Hashtable();
            string[] StringArray=new string[];
            hashTableNews.Add(, StringArray);
            hashTableNews.Add(, );
            hashTableNews.Add(,);
            Console.WriteLine(hashTableNews.);
            object[] Array = new object[];
            hashTable.Add(, "第一");
            hashTable.Add(, "第二");
            hashTable.Add(, "第三");
            hashTable.Add(, "第四");
            hashTable.Add(, "第五");
            hashTable.Add(, "第六");
            #endregion
            #region Contains
            bool ContainsResult = hashTable.Contains();//查找Key值
            Console.WriteLine(ContainsResult);
            bool ContainsKeysResult = hashTable.ContainsKey();//查找Key值
            Console.WriteLine(ContainsKeysResult);
            bool ContainsValueResult = hashTable.ContainsValue("第一");//查找Value值
            Console.WriteLine(ContainsValueResult);
            #endregion
            int i = hashTable.Count;
            Console.WriteLine(i);
            foreach (DictionaryEntry dicEntry in hashTable)
