本文介绍如何使用百度翻译API进行文本翻译，并通过C#实现网页内容抓取及翻译，包括处理网页HTML标签、调用API进行翻译等关键技术。

首先去百度：注册个apikey

然后代码如下只看红色部分就可以了:

using System;

using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Script.Serialization;
using System.Text.RegularExpressions;

namespace Fangyi
{
public partial class _Default : System.Web.UI.Page
{

protected void Page_Load(object sender, EventArgs e)
{
GSEntities db = new GSEntities();
for (int i = 740; i < 900000; i++)
{

try
{
System.Threading.Thread.Sleep(100);
GetUrl("http://www.52mvc.com/story/love/" + i + ".html",db); //采集
}
catch (Exception ex)
{
System.Threading.Thread.Sleep(1500);
}
}
db.Dispose();
}

private void GetUrl(string url, GSEntities db)
{
content cc = new content();
string apikey = "WqLOfG9o2VS1lriX4mz3mDj8";
var enstr = GetHtml.getHtml(url, null);
var title = Regex.Match(enstr.Replace("\n",""), @"<font style\=""font\-size\: 18px\; font\-weight\: bold\;""\>(.+?)\<\/font\>").Groups[1].Value;
enstr = Regex.Replace(enstr, @"\r|\n", "");
enstr = ReHtml(enstr);
enstr = Regex.Match(enstr, @"双击或拖选\)(.+?) ").Groups[1].Value;
var atitle = GetHtml.getHtml("http://openapi.baidu.com/public/2.0/bmt/translate?client_id="
+ apikey + "&q=" + title + "&from=auto&to=auto", null);
JavaScriptSerializer jss2 = new JavaScriptSerializer();
var aa2 = jss2.Deserialize<jsonss>(atitle);
title = aa2.trans_result.First().dst;
enstr = enstr.Trim();
string val = "\t\t";
if (enstr.Length < 2000)
{

int i = 0;
var list = enstr.Replace(" ", "").Replace(""", "“").Split('.').ToList();
list.ForEach(c =>
{
var a = GetHtml.getHtml("http://openapi.baidu.com/public/2.0/bmt/translate?client_id="
+ apikey + "&q=" + c + "&from=auto&to=auto", null);
JavaScriptSerializer jss = new JavaScriptSerializer();
var aa = jss.Deserialize<jsonss>(a);
val += aa.trans_result.First().dst + "。";
++i;
if (i % 5 == 0)
{
System.Threading.Thread.Sleep(15000);
val += "\n\t\t";
}

System.Threading.Thread.Sleep(1000);
});
cc.title = title;
cc.val = val;
db.content.AddObject(cc);
db.SaveChanges();
}
}
public string ReHtml(string HTML)
{
string pattern = @"<[\s\S]*?>";
Regex regex = new Regex(pattern);
HTML = regex.Replace(HTML, "");
return HTML;
}

//中文转为UNICODE字符 forget never

public string ctu(string str)
{
string outStr = "";
if (!string.IsNullOrEmpty(str))
{
for (int i = 0; i < str.Length; i++)
{
//将中文字符转为10进制整数，然后转为16进制unicode字符
outStr += "\\u" + ((int)str[i]).ToString("x");
}
}
return outStr;
}

//UNICODE字符转为中文

public string utc(string str)
{
string outStr = "";
if (!string.IsNullOrEmpty(str))
{
string[] strlist = str.Replace("\\", "").Split('u');
try
{
for (int i = 1; i < strlist.Length; i++)
{
//将unicode字符转为10进制整数，然后转为char中文字符 asp.net
outStr += (char)int.Parse(strlist[i], System.Globalization.NumberStyles.HexNumber);
}
}
catch (FormatException ex)
{
outStr = ex.Message;
}
}
return outStr;
}
}

}
