VS.NET服务中的非ascii字符 [英] Non-ascii characters in VS.NET service
问题描述
我使用VS.NET 2003创建了一个简单的.NET 1.1 Web服务：它有一个
方法，它接受一个字符串参数。它遍历输入字符串，
将每个字符转换为十六进制并将其附加到输出字符串，
返回结果。
我现在在
字段中发送包含非ASCII字符的此服务SOAP消息，该字段将成为输入字符串。每个SOAP消息都有一个XML标头
，它正确描述了非ASCII字符的格式。 （我已经b $ b尝试了iso-8859-1和utf-8）。
出于某种原因，每个XML字符都是非-ASCII已变成
问号？在输入字符串中。实际上，一个UTF-8字符
包含两个字节就成了两个问号。这发生在任何我的代码（或任何代码VS.NET愿意向我展示）运行之前，所以我不知道
知道如何调查一下。在尝试使用
来表示不包含它的字符集中的字符时，通常会生成问号，但在
这种情况下，目标是C＃字符串，这可以代表任何Unicode
字符。
我将不胜感激任何见解。
I''ve created a simple .NET 1.1 web service using VS.NET 2003: it has one
method that takes a string parameter. It iterates through the input string,
turning each character into hex and appending it to an output string, and
returns the result.
I now send this service SOAP messages containing non-ASCII characters in the
field that becomes the input string. Each SOAP message has an XML header
that correctly describes the format of the non-ASCII characters. (I''ve
tried both iso-8859-1 and utf-8).
For some reason, each XML character that''s non-ASCII has been turned into a
question mark "?" in the input string. Actually, a UTF-8 character that
contains two bytes becomes two question marks. This happens before any of
my code (or any code VS.NET is willing to show me) runs, so I''m at a loss to
know how to investigate it. Question marks are often generated when trying
to represent a character in a character set that doesn''t contain it, but in
this case the target is a C# string, which can represent any Unicode
character.
I''d appreciate any insights about this.

如何将字符转换为十六进制？
How is it turning the character into hex?
我现在发送此服务包含非服务的SOAP消息
字段中的-ASCII字符，成为输入字符串。每个SOAP消息都有一个XML标头

XML标题是什么意思？它应该只是在XML
delcaration中。
What do you mean by "an XML header"? It should just be in the XML
delcaration.
由于某种原因，每个非ASCII的XML字符都已被转换进入
问号？在输入字符串中。实际上，一个UTF-8字符
包含两个字节就成了两个问号。
For some reason, each XML character that''s non-ASCII has been turned into a
question mark "?" in the input string. Actually, a UTF-8 character that
contains two bytes becomes two question marks.
这表明无论生成XML文件是什么错误，*或*
您正在查看XML在不合适的编辑器中。你是怎么看
看看XML？

That suggests that whatever''s producing the XML file is wrong, *or*
that you''re looking at the XML in an inappropriate editor. How are you
looking at the XML?

如何将角色变成十六进制？
How is it turning the character into hex?
ret + =" 0x" +（（int）s [i]）。ToString（" X"）;
ret += "0x" + ((int)s[i]).ToString("X");

级别中。

delcaration.
完全正确。每个SOAP消息在其XML
声明中指定正确的编码，如下所示。
Exactly. Each SOAP message specifies the correct encoding in its XML
declaration, as shown below.

<？xml version =" 1.0" encoding =" iso-8859-1"？>
< soap：Envelope xmlns：xsi =" http：//www.w3.org/2001/XMLSchema-instance"

NNTP可能会乱码非ASCII字符，但是以十六进制表示字符串
里面< stags是
141 351 354 346 146
使用od -b验证。
在iso-8859-1中，这些分别是
a，e带有重音，我带有重音，ae，f
我可以在本地解析同一个文件，并观察它是正确的（例如，使用下面的程序获得
）。它仅在网上处理时表现奇怪
服务。
使用System;
使用System.Xml;
命名空间XMLParser
{
class ParseXML
{
static void Main （string [] args）
{
XmlDocument doc = new XmlDocument（）;
doc.Load（" c：\\\ \\ java \\toHex.xml"）;
dumpStrings（doc）;
Console.WriteLine（"< Done>"）;
}
private static void dumpStrings（XmlNode node）
{
if（node is XmlCharacterData）< br $>
{
Console.Out.WriteLine（node.Value）;
}
其他
{
for（XmlNode child = node.FirstChild;
child！= null;
child = child.NextSibling）
{
dumpStrings（child）;
}
}
}
}
}
<?xml version="1.0" encoding="iso-8859-1"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="

<soap:Body>
<ToHex xmlns="http://tempuri.org/">
<s>aéì?f</s>
</ToHex>
</soap:Body>
</soap:Envelope>
NNTP is likely to garble the non-ASCII characters, but in hex the string
inside the <stags is
141 351 354 346 146
verified by using od -b.
In iso-8859-1, these are respectively
a, e with an acute accent, i with a grave accent, ae, f
And I can parse the same file locally and observe that it''s correct (e.g.
with the program below). It only acts oddly when processed by the web
service.
using System;
using System.Xml;
namespace XMLParser
{
class ParseXML
{
static void Main(string[] args)
{
XmlDocument doc = new XmlDocument();
doc.Load("c:\\java\\toHex.xml");
dumpStrings(doc);
Console.WriteLine("<Done>");
}
private static void dumpStrings(XmlNode node)
{
if (node is XmlCharacterData)
{
Console.Out.WriteLine(node.Value);
}
else
{
for (XmlNode child = node.FirstChild;
child != null;
child = child.NextSibling)
{
dumpStrings(child);
}
}
}
}
}

这很奇怪:(
我之前在网络服务中传递了非ASCII字符没有
问题...这很奇怪。
你有一个只有一个网络服务和一个测试应用程序的解决方案
我可以查看一下吗？

That''s pretty odd :(
I''ve passed non-ASCII characters in web services before with no
problems... this is very odd.
Do you have a solution with just a web service and just a test app that
I could have a look at?
