C#借助谷歌翻译实现翻译小工具（一）基本功能实现
软件效果：
实现原理很简单，就是封装谷歌翻译网站：http://translate.google.cn/，一个WebBrowser“肢解”谷歌翻译网站的HtmlElement元素,删除不要的，留下需要的就是了,没什么难度
实现步骤：
一个winform窗体+一个WebBrowser控件
设置WebBrowser的URL为谷歌翻译网站，删除不需要的html元素
全部代码：
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); deleteAllElement(element, "FORM", "gt-form", out element); deleteAllElement(element, "DIV", "gt-text-all", out element); deleteAllElement(element, "DIV", "gt-main", out element); deleteAllElement(element, "DIV", "gt-text-c", out element); deleteElementByID(element, "gt-ft"); //获得gc-text-top元素 foreach (HtmlElement ele in element.Children) { if (ele.Id == "gt-text-top") { element = ele; break; } } #region 去掉 上传，帮助 HtmlElement srcElement = null; foreach (HtmlElement ele in element.Children) { if (ele.Id == "gt-src-c") { srcElement = ele; break; } } deleteAllElement(srcElement, "", "gt-src-p", out srcElement); deleteAllElement(srcElement, "DIV", "gt-src-wrap", out srcElement); #endregion //去掉有错误 #region 去掉 上传，帮助 HtmlElement resElement = null; foreach (HtmlElement ele in element.Children) { if (ele.Id == "gt-res-c") { resElement = ele; break; } } deleteAllElement(resElement, "", "gt-res-p", out resElement); deleteAllElement(resElement, "", "gt-res-data", out resElement); deleteAllElement(resElement, "DIV", "gt-res-wrap", out resElement); deleteElementByID(resElement, "gt-res-tools"); #endregion } void deleteAllElement(HtmlElement HtmlEle, string TagName, string IgroneID, out HtmlElement element) { element = null; if (HtmlEle == null) return; List<HtmlElement> lst = new List<HtmlElement>(); foreach(HtmlElement div in HtmlEle.Children) { if (!String.IsNullOrEmpty(TagName) && div.TagName != TagName) continue; if (div.Id != IgroneID) { lst.Add(div); } else element = div; } foreach (HtmlElement ele in lst) { IHTMLDOMNode node = ele.DomElement as IHTMLDOMNode;//this.webBrowser1.DomElement as mshtml.IHTMLDOMNode; if (node != null) { node.parentNode.removeChild(node); } } } void deleteElementByID(HtmlElement HtmlEle, string DeleteID) { foreach (HtmlElement div in HtmlEle.Children) { if (div.Id == DeleteID) { IHTMLDOMNode node = div.DomElement as IHTMLDOMNode;//this.webBrowser1.DomElement as mshtml.IHTMLDOMNode; if (node != null) { node.parentNode.removeChild(node); } return; } } } }
