c# – 如何更改DataContractSerializer文本编码？

DataContractSerializer的WriteObject方法具有写入Stream或XmlWriter(和XmlDictionaryWriter)的重载. Stream过载将默认为UTF-8,因此您需要使用另一个.使用在UTF-16中编写 XML的 XML Writer实例可以执行您所需要的操作,因此您可以执行@Phil建议的操作,也可以使用XmlDictionaryWriter.CreateTextWriter返回的作者作为参数传递Encoding.Unicode .

    [DataContract(Name = "Person",Namespace = "http://my.namespace")]
    public class Person
    {
        [DataMember]
        public string Name { get; set; }
        [DataMember]
        public int Age { get; set; }
    }
    public static void Test()
    {
        MemoryStream ms = new MemoryStream();
        XmlDictionaryWriter writer = XmlDictionaryWriter.CreateTextWriter(ms,Encoding.Unicode);
        DataContractSerializer dcs = new DataContractSerializer(typeof(Person));
        Person instance = new Person { Name = "John Doe",Age = 33 };
        dcs.WriteObject(writer,instance);
        writer.Flush(); // Don't forget to Flush the writer here
        Console.WriteLine("Decoding using UTF-16: {0}",Encoding.Unicode.GetString(ms.ToArray()));
    }
