1.<globalization
requestencoding="gb2312"
responseencoding="gb2312"
/>
或者 <meta http-equiv="content-type" content="text/html; charset=gb2312">
2.下载文件时指定文件名,中文的文件名出现了乱码?
response.addheader("content-disposition", "attachment; filename="+httputility.urlencoding(filename.tostring ()));
3.如何识别字符串中是否包含韩文
http://search.csdn.net/expert/topic/2456/2456407.xml?temp=.5485498
如果只有英文和韩文
/*******该函数返回字符串中除英文外的字符*********/
create function test(@a varchar(20))
returns varchar(20)
as
begin
declare @b varchar(20),@i int
set @b = ''
set @i = 1
while @i<= len(@a)
begin
if upper(substring(@a,@i,1)) not between 'a' and 'z'
set @b = @b + substring(@a,@i,1)
set @i = @i+1
end
return @b
end
select dbo.test('aabc12dsa451')
--------------------
12451
(所影响的行数为 1 行) --1.有关多国文字的,一定要用unicode判断!
--2.韩文unicode分两断: 12592->12687 44032->55203
相关网站:http://www.buja.8u8.com/eeeeee.htm
create function hw(@str nvarchar(100))
returns int
as
begin
declare @a int
set @a=0
while @str<>'' and @a=0
begin
set @a=(case when unicode(left(@str,1)) between 12592 and 12687
or unicode(left(@str,1)) between 44032 and 55203
then 1
else 0 end)
set @str=right(@str,len(@str)-1)
end
return @a
end
--调用:
declare @a nvarchar(100)
set @a=n'abc中갃国123'
select dbo.hw(@a)
--return: 1
set @a=n'abc中国123'
select dbo.hw(@a)
--return: 0
4.为什么文件读出来的中文字符是乱码?
system.io.streamreader m_fs = system.io.file.opentext(hfile_selectfile.value);
改为 system.io.streamreader m_fs = new system.io.streamreader(hfile_selectfile.value,system.text.encoding.getencoding("gb2312"));
5.jmail 发邮件附件或者没有或者在正文中是乱码

6.怎么解决查询字符串中文乱码问题?
查询内容用server.urlencode编码
string url ="http://localhost/test/test.aspx?a="+ server.urlencode("张三");
解
-->server.urldecode()
