读取XML文件时出错

linq-to-xml xml-serialization serialization xml c#

Sam · 技术社区 · 13 年前

            Person person = GetPerson();
            XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
            ns.Add(string.Empty, string.Empty);
            XmlSerializer serializer = new XmlSerializer(typeof(Person));
            string personText = string.Empty;
            using (MemoryStream memoryStream = new MemoryStream())
            {
                using (XmlWriter xmlWriter = XmlWriter.Create(memoryStream, new XmlWriterSettings() { Encoding = Encoding.UTF8 }))
                {
                    serializer.Serialize(xmlWriter, person, ns);
                    xmlWriter.Flush();
                    personText = Encoding.UTF8.GetString(memoryStream.ToArray());
                }
            }

            string path = @"D:\person.xml";
// Write method 1:
            File.WriteAllText(path, personText);

// Write method 2:
            using (StreamWriter streamWriter = new StreamWriter(path, false , Encoding.UTF8))
            {
                streamWriter.Write(personText);
            }

// Read the xml
            using (FileStream fileStream = new FileStream(path, FileMode.Open))
            {
                return XDocument.Load(XmlReader.Create(fileStream));
            }

当我在使用方法2编写之后读取xml时,我在根级别得到的数据是无效的。第1行,位置1。但使用方法1效果良好。

是什么原因造成的?感谢任何指点。
