C# hashtable如何更新内部所有value

主要实现代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;

namespace AlignForHashtable
{
    class Program
    {
        private static Hashtable mHTable = new Hashtable();

        private static void initHTable()
        {
            mHTable.Clear();
            for (int i = 0; i < 10; i++)
            {
                mHTable.Add(i, "Value" + i);
            }
        }

        // Batch update all the element value .....
        private static void updateHashtableValue(string newValue)
        {
            Hashtable htable = new Hashtable();
            foreach (DictionaryEntry de in mHTable)
            {
                string valueStr = newValue;
                htable.Add(de.Key, valueStr);
            }

            mHTable.Clear();
            mHTable = htable;

            /* Error Usage ... */
            //Hashtable htable = this.mHTable;
            //this.mHTable.Clear();
            //string valueStr = string.Empty;

            //foreach (DictionaryEntry de in htable)
            //{
            //    valueStr = newValue;
            //    this.mHTable.Add(de.Key, valueStr);
            //}
        }

        static void Main(string[] args)
        {

            Console.WriteLine("Before update ..... \n");
            initHTable();

            foreach (DictionaryEntry de in mHTable)
            {
                Console.WriteLine("Key={0},Value={1}", de.Key, de.Value);
            }

            updateHashtableValue("NBA all stars...");

            Console.WriteLine();
            Console.WriteLine("After update ..... \n");

            foreach (DictionaryEntry de in mHTable)
            {
                Console.WriteLine("Key={0},Value={1}", de.Key, de.Value);
            }

            Console.ReadLine();
        }

    }
}

注意！上面代码中，屏蔽代码的更新方法是错误的。

需要留意！！
