要使用任意编码加载XML文件,我有以下代码：
Encoding encoding;
using (var reader = new XmlTextReader(filepath))
{
reader.MoveToContent();
encoding = reader.Encoding;
}
var settings = new XmlReaderSettings { NaMetable = new NaMetable() };
var xmlns = new XmlNamespaceManager(settings.NaMetable);
var context = new XmlParserContext(null,xmlns,"",XmlSpace.Default,encoding);
using (var reader = XmlReader.Create(filepath,settings,context))
{
return XElement.Load(reader);
}
这有效,但打开文件两次似乎有点低效.是否有更好的方法来检测编码,以便我可以这样做：
1. Open file 2. Detect encoding 3. Read XML into an XElement 4. Close file
好的,我应该早点想到这个. XmlTextReader(它给我们编码)和XmlReader.Create(允许我们指定编码)接受Stream.那么首先打开一个FileStream,然后将它与XmlTextReader和XmlReader一起使用,如下所示：

{
using (var xmlreader = new XmlTextReader(txtreader))
{
// Read in the encoding info
xmlreader.MoveToContent();
var encoding = xmlreader.Encoding;
// Rewind to the beginning
txtreader.Seek(0,SeekOrigin.Begin);
var settings = new XmlReaderSettings { NaMetable = new NaMetable() };
var xmlns = new XmlNamespaceManager(settings.NaMetable);
var context = new XmlParserContext(null,encoding);
using (var reader = XmlReader.Create(txtreader,context))
{
return XElement.Load(reader);
}
}
}
