Question

在尝试回答另一个问题时，我正在将C＃对象序列化为XML字符串。这真是令人惊讶的困难;这是我能提出的最短的代码片段：

var yourList = new List<int>() { 1, 2, 3 };
var ms = new MemoryStream();
var xtw = new XmlTextWriter(ms, Encoding.UTF8);
var xs = new XmlSerializer(yourList.GetType());
xs.Serialize(xtw, yourList);
var encoding = new UTF8Encoding();
string xmlEncodedList = encoding.GetString(ms.GetBuffer());

结果没问题：

<?xml version="1.0" encoding="utf-8"?>
<ArrayOfInt
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <int>1</int>
    <int>2</int>
    <int>3</int>
</ArrayOfInt>

但是这个片段比我想象的要复杂得多。我无法相信你必须知道编码和MemoryStream这个简单的任务。

是否有更短的方法将对象序列化为XML字符串？

Answer 1

短一点： - ）

var yourList = new List<int>() { 1, 2, 3 };
using (var writer = new StringWriter())
{
    new XmlSerializer(yourList.GetType()).Serialize(writer, yourList);
    var xmlEncodedList = writer.GetStringBuilder().ToString();
}

尽管这种先前方法存在缺陷值得指出。它会在我们使用StringWriter时生成utf-16标头，因此它与您的代码不完全相同。要获得utf-8标题，我们应该使用MemoryStream和XmlWriter这是另外一行代码：

var yourList = new List<int>() { 1, 2, 3 };
using (var stream = new MemoryStream())
{
    using (var writer = XmlWriter.Create(stream))
    {
        new XmlSerializer(yourList.GetType()).Serialize(writer, yourList);
        var xmlEncodedList = Encoding.UTF8.GetString(stream.ToArray());
    }
}

Answer 2

如果您要使用UTF8编码，就可以这样做

public class StringWriterUtf8 : System.IO.StringWriter
{
    public override Encoding Encoding
    {
        get
        {
            return Encoding.UTF8;
        }
    }

}

然后像这样使用StringWriter的StringWriterUtf8读取

        using (StringWriterUtf8 textWriter = new StringWriterUtf8())
        {

            serializer.Serialize(textWriter, tr, ns);

            xmlText = textWriter.ToString();
        }

Answer 3

编写扩展方法或包装类/函数来封装代码段。

Answer 4

您不需要MemoryStream，只需使用StringWriter：

var yourList = new List<int>() { 1, 2, 3 };
using (StringWriter sw = new StringWriter())
{
    var xs = new XmlSerializer(yourList.GetType());
    xs.Serialize(sw, yourList);
    string xmlEncodedList = sw.ToString();
}
