首先建立語言檔，在項目中加入.resx文件
例如：
message.zh-cn.resx '簡體中文
message.zh-tw.resx '繁體中文
message.en '英文
..............
=========================================
然后利用Name --Value 鍵值對 填入你要在頁面上顯示的語言
如：
name value
message.zh-cn.resx中：
res_loginbname 登陸名 :
message.zh-tw.resx中：
res_loginbname 登陸名 :
message.zh-cn.resx中：
res_loginbname Login Name :

=========================================
然后在Golbal.asax中加入多語言設定支持代碼（瀏覽器需要支持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中加入如下代碼，用于設定編碼和默認語種，在Global.asax中有調用：

=========================================
<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>

=========================================
頁面代碼中使用多語言支持：

Imports System.Resources

Public Class 類名
Inherits System.Web.UI.Page
PRotected LocRM As ResourceManager = New ResourceManager("項目文件名.message", GetType(類名).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

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

到這里多語言支持的工作就作完了，接下來自己去慢慢Key
message.zh-cn.resx '簡體中文
message.zh-tw.resx '繁體中文
message.en '英文

這幾個語言檔吧
