asp.net + oracle 显示乱码问题！！急！！

[numen73]

环境 winserver2003+ oracle8.1+vs.net2003

原先用powerbuilder 写入数据库的数据读出来都是乱码！

在vs.net2003调试过程中更改原先的乱码写入数据库后，
再次调试，改过的字段变成了????
在oracle客户端试过一下字符集：
SIMPLIFIED CHINESE_CHINA.ZHS16GBK
American_America.us7ascII
AMERICAN_AMERICA.WE8ISO8859P1
也是过一下配置：
<configuration>
<system.web>
<globalization requestEncoding="GB2312" responseEncoding="GB2312" uiCulture="zh-CN" culture="zh-CN" fileEncoding="GB2312" />
</system.web>
</configuration>
machine.config也如下改过
<globalization requestEncoding="GB2312" responseEncoding="GB2312"/>


怎么回事？？？ 很急呀！！

run SQL*Plus and do a query, is your data in Chinese? or you see "????"? are you using unicode type like nchar/nvarchar?

[numen73]

the result of a query in SQL*Plus is
I???????O????<>?'u?i??
why ?
I don't use unicode type like nchar/nvarchar .

将web.config文件中的
<globalization requestEncoding="utf-8" responseEncoding="utf-8" />
中的utf-8 改成 gb2312

[numen73]

web.config文件
<?xml version="1.0" encoding="gb2312" ?>
<globalization

requestEncoding="gb2312"
responseEncoding="gb2312"
uiCulture="zh-CN"
culture="zh-CN" fileEncoding="GB2312"

/>


*.aspx文件
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

oracle 客户端NLS_LANG AMERICAN_AMERICA.WE8ISO8859P1

sql*plus 取出原先的数据可以正常显示。
