如何改变XML的编码？

Question

我生成的XML编码是GBK的，我想在读取的时候把编码改成UTF-8的，有没有人做过呀，急用的，请高手赐教，谢谢了！

Answer 1

using (StreamReader reader = new StreamReader(path, Encoding.UTF8))
                {
                    StreamReader.Synchronized(reader);
                    commonFileXml = reader.ReadToEnd();
                    reader.Close();
                }

Answer 2

 public static string ToXml(this XDocument doc)
        {
            StringBuilder output = new StringBuilder();            using (XmlWriter writer = XmlWriter.Create(new StringWriterWithEncoding(output), new XmlWriterSettings { Indent = false, Encoding = Encoding.UTF8}))
            {
                if (writer != null)
                {
                    doc.Save(writer);
                }
            }            return output.ToString();
        }

问题解决
解决方法：
private static void ReaderXml(DataSet thisDataSet, string filename)
        {
            if (thisDataSet == null)
            {
                return;
            }
            StreamReader inStream = new StreamReader(filename, Encoding.GetEncoding(936));//关键就是这个数字了  936代表转化为GB2312
            thisDataSet.ReadXml(inStream);
            inStream.Close();
        }
