Question

            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));
            }

当我使用方法2写入后读取xml时，我在根级别获取此数据无效。第1行，第1位。但使用方法1可以正常工作。

造成这种情况的原因是什么？任何指针都赞赏。

Answer 1

问题在于StreamWriter 和 XmlWriter都添加了字节顺序标记。

选项：

将BOM从personText串起来以
为new UTF8Encoding(false)

Encoding.UTF8

StreamWriter

为new UTF8Encoding(false)

Encoding.UTF8

XmlWriter

首先避免转换为文本并再次返回：您在MemoryStream中获得了二进制数据，为什么不将转储到磁盘？
