軟件效果：

實現原理很簡單，就是封裝谷歌翻譯網站：http://translate.google.cn/，一個WebBrowser“肢解”谷歌翻譯網站的HtmlElement元素,刪除不要的，留下需要的就是了,沒什么難度

實現步驟：

一個winform窗體+一個WebBrowser控件

設置WebBrowser的URL為谷歌翻譯網站，刪除不需要的html元素

全部代碼：

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.Shown += Form1_Shown;
        }
        const string url = "http://translate.google.cn/?hl=zh-cn#zh-CN/en/%E6%9D%A5%E8%87%AA%0Ahttp%3A%2F%2Ftranslate.google.cn%2F";
        private void Form1_Load(object sender, EventArgs e)
        {
            webBrowser1.IsWebBrowserContextMenuEnabled = false;
            webBrowser1.ScriptErrorsSuppressed = true;
            webBrowser1.Url = new Uri(url);
        }
        void Form1_Shown(object sender, EventArgs e)
        {
            while (webBrowser1.Document == null)
                Application.DoEvents();
            HtmlElement element;
            deleteAllElement(webBrowser1.Document.Body, "DIV", "gt-c", out element);
            deleteAllElement(element, "DIV", "gt-form-c", out element);

            deleteElementByID(element, "gt-ft");

            //獲得gc-text-top元素
            foreach (HtmlElement ele in element.Children)
            {
                if (ele.Id == "gt-text-top")

                    break;
                }
