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
