首先建立语言档，在项目中加入.resx文件
例如：
message.zh-cn.resx '简体中文
message.zh-tw.resx '繁体中文
message.en '英文
..............
=========================================
然后利用Name --Value 键值对 填入你要在页面上显示的语言
如：
name value
message.zh-cn.resx中：
res_loginbname 登陆名 :
message.zh-tw.resx中：
res_loginbname 登陸名 :
message.zh-cn.resx中：
res_loginbname Login Name :

=========================================
然后在Golbal.asax中加入多语言设定支持代码（浏览器需要支持Cookie）

'=========================================
' Application_BeginRequest Event
'
' The Application_BeginRequest method is an ASP.NET event that executes
' on each web request into the portal application.
'
' The thread culture is set for each request using the language
' settings
'
'=========================================
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs)
Try
If Not Request.Cookies("resource") Is Nothing Or Request.Cookies("resource").Value = "" Then
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(Request.Cookies("resource").Value)
Else
Thread.CurrentThread.CurrentCulture = New CultureInfo(ConfigurationSettings.AppSettings("DefaultCulture"))
End If
Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture
Catch ex As Exception
Thread.CurrentThread.CurrentCulture = New CultureInfo(ConfigurationSettings.AppSettings("DefaultCulture"))
End Try
End Sub 'Application_BeginRequest

在Web.Config中加入如下代码，用于设定编码和默认语种，在Global.asax中有调用：

=========================================
<globalization requestEncoding="utf-8" responseEncoding="utf-8" />
<appSettings>
<add key="DefaultCulture" value="zh-cn" />
<!-- zh-cn:簡體中文 zh-tw:繁體中文 en:英文 -->
</appSettings>

=========================================
页面代码中使用多语言支持：

Imports System.Resources

Public Class 类名
Inherits System.Web.UI.Page
Protected LocRM As ResourceManager = New ResourceManager("项目文件名.message", GetType(类名).Assembly)

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
lblLogin.Text = LocRM.GetString("res_login")
End Sub
End Class

=========================================

到这里多语言支持的工作就作完了，接下来自己去慢慢Key
message.zh-cn.resx '简体中文
message.zh-tw.resx '繁体中文
message.en '英文

这几个语言档吧
