这篇文章是测试如何将西文页面上显示中文的，将Web.Config文件中的globalization节点修改为西文设置，
<globalization culture="en-US" requestEncoding="iso-8859-1" responseEncoding="iso-8859-1" />可以在页面显示编码为西文，那又如何能在此西文页面上显示存储中文信息呢，
建立ASPX页面进行测试：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="UnicodeToGB2312.aspx.cs" Inherits="UnicodeToGB2312" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" ><head runat="server"> <title>Untitled Page</title> <script language="javascript" type="text/javascript">
function encode(obj)
{
alert(0); var hidTxt = document.getElementById("hidTxtContent"); hidTxt.value=obj.value.replace(/[^\u0000-\u00FF]/g,function($0){return escape($0).replace(/(%u)(\w{4})/gi,"$2;")}); var aa = hidTxt.value.split("&"); var bb = ""; for(var i=1; i<aa.length; i++) { bb = bb + "&" + aa[i];
} // hidTxt.value=hidTxt.value.replace("&", "&"); hidTxt.value=bb; alert(hidTxt.value); } function unencode(obj) { obj.value=unescape(obj.value.replace(//g,'%u').replace(/;/g,'')); } function setTextValueFromHidden() { var text = document.getElementById("txtContent"); var lblValue = document.getElementById("lblValue"); text.value = lblValue.innerText; lblValue.style.display = "none"; }
</script></head><body onload="setTextValueFromHidden()"> <form id="form1" runat="server"> <input id="hidTxtContent" type="hidden" name="hidTxtContent" runat="server"> <asp:Label ID="lblValue" runat="server" Text="Label" ></asp:Label><div style="text-align: center"> <asp:TextBox ID="txtContent" runat="server" Height="262px" TextMode="MultiLine" Width="492px"></asp:TextBox> <br /> <br /> <asp:Button ID="btnConvert" runat="server" Text="escape" OnClick="btnConvert_Click" Height="24px" Width="59px" /> <br /> <br /> <br /> <asp:Button ID="Button1" runat="server" Text="Button" /></div> </form></body></html>后台代码：
using System;using System.Data;using System.Text;using System.Text.RegularExpressions;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;public partial class UnicodeToGB2312 : System.Web.UI.Page{ protected void Page_Load(object sender, EventArgs e) { this.btnConvert.Attributes.Add("onclick", "encode(" + this.txtContent.ID + ");"); } protected void btnConvert_Click(object sender, EventArgs e) { string result = txtContent.Text; result = this.hidTxtContent.Value; result = result.Replace("&", "&"); result = UnEncode(result); result = Encode(result); this.lblValue.Text = result; } protected string Encode(string inputString) { MatchEvaluator matchEvaluator = new MatchEvaluator(EncodeFindSubString); //初始化一个委托,该委托用于处理Regex.Repalce中每次匹配的match对象 string result = System.Text.RegularExpressions.Regex.Replace(inputString, @"[^\u0000-\u00FF]", matchEvaluator); return result; } protected string UnEncode(string inputString) { MatchEvaluator matchEvaluator = new MatchEvaluator(UnEncodeFindSubString); string result = System.Text.RegularExpressions.Regex.Replace(inputString, @"([0-9a-fA-F]{4});", matchEvaluator); return result; } protected string EncodeFindSubString(Match match) //编码的时候委托处理函数 { byte[] bytes = Encoding.Unicode.GetBytes(match.Value); string result = ""; for (int i = bytes.Length - 1; i >= 0; i--) { result += ToHexString(bytes[i]); } result = "" + result + ";"; return result; } protected string UnEncodeFindSubString(Match match) //解码的时候委托处理函数 { string result = match.Groups[1].Value; byte[] bytes = new byte[2]; //4E 2D bytes[1] = byte.Parse(result.Substring(0, 2), System.Globalization.NumberStyles.AllowHexSpecifier); bytes[0] = byte.Parse(result.Substring(2, 2), System.Globalization.NumberStyles.AllowHexSpecifier); result = result.Replace(result, Encoding.Unicode.GetString(bytes)); return result; } protected string ToHexString(byte a) //返回一个16进制表示的数 { string result = a.ToString("X"); if (result.Length == 2) { return result; } else { return "0" + result; //如果就一位比如"7"的16进制返回的是"7"而我们需要 "07" } } }这样就可以完成此功能。
