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;
}
}
}
