Asp.net中的页面乱码的问题
1.＜globalization
requestEncoding="gb2312"
responseEncoding="gb2312"
/>
或者 requestEncoding="gb2312"
responseEncoding="gb2312"
/>
＜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） 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
--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

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
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()
