字典类：
using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;namespace Dict
{
    public class ClassDict
    {
        private Hashtable words = new Hashtable();
        public  ClassDict()
        {
            words.Add("lock", "锁");
            words.Add("name", "名字");
            words.Add("engine", "发动机");
            words.Add("carframe", "车架");
            words.Add("file", "文件");
            words.Add("folder", "文件夹");
        }        public string this[string sEnglish]
        {
            get
            {
                foreach(DictionaryEntry dKey in words)
                {
                    if (dKey.Key.ToString() == sEnglish.ToLower())
                    {
                        return dKey.Value.ToString();
                    }
                }
                return "对不起，没找到对应汉字翻译！";
            }
        }        public string this[object oChinese]
        {
            get
            {
                foreach (DictionaryEntry dKey in words)
                {
                    if (dKey.Value.ToString() == oChinese.ToString())
                    {
                        return dKey.Key.ToString();
                    }
                }
                return "对不起，没找到对应英文翻译！";
            }
        }
    }
}查中英文翻译：
        private void button1_Click(object sender, EventArgs e)
        {
            if(string.IsNullOrEmpty(textBox1.Text.Trim())==false)
            {
                ClassDict classDict1 = new ClassDict();
                char c1 = textBox1.Text.Trim()[0];
                if ((int)c1 >= 0x4e00 && (int)c1 <= 0x9fa5)
                {
                    //如果是汉字，就查英文
                    object o1 = textBox1.Text.Trim();
                    textBox2.Text = classDict1[o1];
                }
                else
                {
                    //如果是英文，就查汉字
                    textBox2.Text = classDict1[textBox1.Text];
                }
            }
        }

Answer 1

看了一下，连hello world都没有

Answer 2

用Dictionary<string, string>效率更高。

Answer 3

数据量不大Dictionary、SortedDictionary、SortedList在搜索上都差不多
如果数据量非常大,应该使用SortedDictionary

Answer 4

看了一下，连hello world都没有呵呵，添加一下就可以了！
words.Add("hello world", "欢迎来到CSDN!哈哈");

 阿捷 

  

Answer 5

谢谢。改成这样了     public class ClassDict
    {
        private SortedDictionary<string,string> words = new SortedDictionary<string,string>();
        public  ClassDict()
        {
            words.Add("lock", "锁");
            words.Add("china", "中国");
        }        public string this[string sEnglish]
        {
            get
            {
                foreach(KeyValuePair<string,string> word in words)
                {
                    if(word.Key ==sEnglish.ToLower())
                    {
                        return word.Value;
                    }
                }
                return "对不起，没找到对应汉字翻译！";
            }
        }        public string this[object oChinese]
        {
            get
            {
                foreach (KeyValuePair<string, string> word in words)
                {
                    if (word.Value == oChinese.ToString())
                    {
                        return word.Key;
                    }
                }
                return "对不起，没找到对应英文翻译！";
            }
        }
