介绍
声明性资源表达式可使您的应用程序使用多种语言,而不必手动编写代码来检索资源并在页中进行替换。您只需使用 ASP.NET 2.0
中新提供的表达式语法即可对资源替换进行定义。ASP.NET 2.0 支持标准的 resx
文件格式自动进行运行时资源检索。
关键
1、Culture - 决定各种数据类型是如何组织,如数字与日期;UICulture -
决定了采用哪一种本地化资源,也就是使用哪种语言。在页的@Page指令中或者配置文件的<system.web><globalization>元素中设置(另外该元素内还可以设置属性requestEncoding,responseEncoding,fileEncoding)。Culture="en-us"和Culture="auto:en-us"的区别在于,后者会先自动匹配,无法自动匹配则用en-us;
2、HTTP
允许浏览器使用“接受语言”(Accept-Language) HTTP 请求标头字段将一个首选语言列表发送到 Web 服务器。在IE中选择工具 -
Internet 选项 -
语言;
3、web.sitemap应用本地化的时候设置<siteMap>的属性enableLocalization="true"。访问全局资源:$Resources:
全局资源名, 资源内的key,
默认值;或者resourceKey="web.sitemap.resx文件中的key";
4、编程方式处理用GetGlobalResourceObject()
和 GetLocalResourceObject();
5、编程设置Culture 和
UICulture请重写InitializeCulture(),对 Thread.CurrentThread.CurrentCulture 和
Thread.CurrentThread.CurrentUICulture进行设置;
6、访问全局资源:$
Resources:全局资源名,资源内的key;显式访问本地资源:$
Resources:key.属性;隐式访问本地资源:meta:resourcekey="key"。
示例
本地化测试
Localization/Test.aspx
Code
<%@ Page Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Test.aspx.cs"
Inherits="Localization_Test" Title="本地化测试" Culture="en-us" UICulture="en-us"
meta:resourcekey="Title" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
<p>
目前语言:
<asp:Label ID="lblCurrentCulture" runat="Server" />
</p>
<p>
当前时间:
<%=DateTime.Now %>
</p>
<p>
隐式:
<asp:Label ID="lbl" runat="server" meta:resourcekey="lbl" /></p>
<p>
显式:
<asp:Label ID="lbl2" runat="server" Text="<%$ Resources:lbl.Text %>" ToolTip="<%$ Resources:lbl.ToolTip %>" />
</p>
<p>
全局:
<asp:Label ID="lbl3" runat="Server" Text="<%$ Resources:MyGlobal,GlobalText %>" />
</p>
<p>
编码方式(全局资源):
<asp:Label ID="lbl4" runat="server" />
</p>
<p>
编码方式(本地资源):
<asp:Label ID="lbl5" runat="server" />
</p>
<p>
Localize控件方式(Label控件到客户端会解析成<span>,而Localize到客户端后就是解析成其所包含的文字):
<asp:Localize ID="AboutUs" runat="server" meta:resourcekey="AboutUs"></asp:Localize>
</p>
<p>
<a href="?currentculture=zh-cn">中文</a>
<a href="?currentculture=en-us">英文</a>
</p>
<p>
注:<br />
Culture - 决定各种数据类型是如何组织,如数字与日期<br />
UICulture - 决定了采用哪一种本地化资源,也就是使用哪种语言
