XmlWriter编码问题 [英] XmlWriter encoding issues

问题描述

我有以下代码：

    MemoryStream ms = new MemoryStream();
    XmlWriter w = XmlWriter.Create(ms);

    w.WriteStartDocument(true);
    w.WriteStartElement("data");

    w.WriteElementString("child", "myvalue");

    w.WriteEndElement();//data
    w.Close();
    ms.Close();

    string test = UTF8Encoding.UTF8.GetString(ms.ToArray());

正确生成XML;但是，我的问题是字符串'test'的第一个字符是ï（char＃239），使其对一些xml解析器无效：这是从哪里来的？我正在做什么错误？

The XML is generated correctly; however, my problem is the first character of the string 'test' is ï (char #239), making it invalid to some xml parsers: where is this coming from? What exactly am I doing incorrectly?

我知道我可以通过刚刚开始的第一个角色解决问题，但我宁愿知道为什么它在那里，而不是简单地修补

I know I can resolve the issue by just starting after the first character, but I'd rather know why it's there than simply patching over the problem.

谢谢！

Found one solution here: http://www.timvw.be/generating-utf-8-with-systemxmlxmlwriter/

我在顶部缺少这个：

XmlWriterSettings xmlWriterSettings = new XmlWriterSettings();
xmlWriterSettings.Encoding = new UTF8Encoding(false);
MemoryStream ms = new MemoryStream();
XmlWriter w = XmlWriter.Create(ms, xmlWriterSettings);
