为什么总的XmlWriter允许输出UTF-16编码？ [英] Why is the XmlWriter always outputing utf-16 encoding?

问题描述

我有这样的扩展方法

    public static string SerializeObject<T>(this T value)
    {
        var serializer = new XmlSerializer(typeof(T));           
        var settings = new XmlWriterSettings
                       {
                        Encoding = new UTF8Encoding(true), 
                        Indent = false, 
                        OmitXmlDeclaration = false,
                        NewLineHandling = NewLineHandling.None
                       };

        using(var stringWriter = new StringWriter()) 
        {
            using(var xmlWriter = XmlWriter.Create(stringWriter, settings)) 
            {
                serializer.Serialize(xmlWriter, value);
            }

            return stringWriter.ToString();
        }
    }

但每当我把这个它有一个编码 UTF-16 规定，即<？XML版本=1.0编码=UTF-16> 。我在做什么错了？

but whenever I call this it has an encoding of utf-16 specified, ie <?xml version="1.0" encoding="utf-16"?>. What am I doing wrong?

推荐答案

字符串是UTF-16，所以写入的StringWriter将始终使用UTF-16。如果这不是你想要的，然后使用一些其他的的TextWriter 派生类中，与你喜欢的编码。

Strings are UTF-16, so writing to a StringWriter will always use UTF-16. If that's not what you want, then use some other TextWriter derived class, with the encoding you like.
