我有一个创建一些XmlDocument的函数:

public string CreateOutputXmlString(ICollection<Field> fields)
{
    XmlWriterSettings settings = new XmlWriterSettings();
    settings.Indent = true;
    settings.Encoding = Encoding.GetEncoding("windows-1250");

    StringBuilder builder = new StringBuilder();
    XmlWriter writer = XmlWriter.Create(builder, settings);

    writer.WriteStartDocument();
    writer.WriteStartElement("data");
    foreach (Field field in fields)
    {
        writer.WriteStartElement("item");
        writer.WriteAttributeString("name", field.Id);
        writer.WriteAttributeString("value", field.Value);
        writer.WriteEndElement();
    }
    writer.WriteEndElement();
    writer.Flush();
    writer.Close();

    return builder.ToString();
}

我设置了一个编码,但在我创建XmlWriter后,它确实有utf-16编码.我知道这是因为字符串(和我猜想的StringBuilder)是用utf-16编码的,你无法改变它.
那么如何在编码属性设置为"windows-1250"的情况下轻松创建此xml？它甚至不必在这种编码中编码,它只需具有指定的属性.

编辑:它必须在.Net 2.0中,因此不能使用任何新的框架元素.

当我遇到它时,我感到很惊讶,并编写了一个控制台应用程序来检查它,并确保我没有做任何其他事情.

有谁能解释一下？

这是代码:

using System.IO;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;

namespace ConsoleApplication1

        static void Main(string[] args)
        {
            var o = new SomeObject { Field1 = "string value", Field2 = 8 };

            Console.WriteLine("ObjectToXmlViaStringBuilder");
            Console.Write(ObjectToXmlViaStringBuilder(o));
            Console.WriteLine();
            Console.WriteLine();
            Console.WriteLine("ObjectToXmlViaStream");
            Console.Write(StreamToString(ObjectToXmlViaStream(o)));
            Console.ReadKey();
        }

        public static string ObjectToXmlViaStringBuilder(SomeObject someObject)
        {
            var output = new StringBuilder();
            var settings = new XmlWriterSettings { Encoding = Encoding.UTF8, Indent = true };

            using (var xmlWriter = XmlWriter.Create(output, …
