注册会员，创建你的web开发资料库， 1 function removehtml()function removehtml(strhtml)
2 if strhtml<>"" then
3 dim s_str as string
4 s_str=regex.replace(strhtml,"<[^>]+>","")
5 s_str=replace(s_str," ","")
6 return s_str
7 end if
8 end function

10 function china_to_english()function china_to_english(texts,languages)
11 dim payload as string = "hl=zh-cn&ie=utf8&text="& texts &"&langpair="& languages &""
12 dim str_return as string
13 dim req as webrequest = webrequest.create("http://translate.google.com/translate_t") ' 开始取连接.
14 req.credentials = credentialcache.defaultcredentials '取得默认
15 req.method = "post" '以post方式发送，这里默认是以get方式发送
16 req.contenttype = "application/x-www-form-urlencoded" 'post方式需在传送这个编码，如果上传文件，则修为multipart/form-data
17 req.timeout=10000 '连接超时定时
18 req.contentlength = payload.length '头部长度
19 dim encoding as encoding = encoding.getencoding("utf-8") '转换成流,大部网站一般转换成utf-8就可以了，注意是大写的编码
20 dim bytes as byte() = encoding.getbytes(payload) '转换成流
21 req.contentlength = bytes.length '传送流的长度
22 dim newstream as stream = req.getrequeststream() '转换写入
23 newstream.write(bytes, 0, bytes.length) '写入传送流
24 newstream.close() '关闭
25 '上面发送完成，下面取得服务器返回
26 dim res as httpwebresponse = ctype(req.getresponse(), httpwebresponse) ' 传递返回标识
27 if res.statusdescription="ok" then ' 返回取得状态.
28 current.response.write("暂时无法连接到网站,请换用另一个程序")
29 current.response.end()
30 end if
31 dim datastream as stream = res.getresponsestream() ' 返回给指针
32 dim reader as new streamreader(datastream,encoding.getencoding("gb2312")) ' 读
33 dim responsefromserver as string = reader.readtoend() ' 读取所有
34
35 str_return=responsefromserver '赋值回传
36
37 reader.close() '接下来三个关闭
38 datastream.close()
39 res.close()
40
41 dim ss as string = str_return
42 ss = regex.replace(ss,"(?i:(.+)(/<div)(.+)(/>)(.+)(/<//div/>)(.+))","$5") '提取我们所要的译文
43 ss = removehtml(ss) '删除html
44 ss = ss.substring(3) '删除翻译二字
45 return ss '函数返回
46 end function
47
48 在调用china_to_english(texts,languages)需要传两个参数第一个为要译的文字,第二个是要进行相对译的语种代码.
例:中译英,其第二个参数为:zh-cn|en
我导入的命名空间如下:
imports system
imports system.web
imports system.io
imports microsoft.visualbasic
imports system.web.httpcontext
imports system.web.ui
imports system.web.ui.webcontrols
imports system.text
imports system.text.regularexpressions
imports system.net
