容易序列化的C＃类为XML文本方式 [英] Easier way to serialize C# class as XML text

问题描述

在试图回答另一个问题，我是一个序列化的C＃对象的XML字符串。这是令人惊讶的辛苦;这是最短的代码片段，我可以想出：

While trying to answer another question, I was serializing a C# object to an XML string. It was surprisingly hard; this was the shortest code snippet I could come up with:

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());

其结果是好的：

The result is okay:

<?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>

但片段是比我想应该是更加复杂。我不能相信你必须了解编码的MemoryStream对于这个简单的任务。

But the snippet is more complicated than I think it should be. I can't believe you have to know about encoding and MemoryStream for this simple task.

有序列化对象到XML字符串较短的方式？

Is there a shorter way to serialize an object to an XML string?

推荐答案

一个短一点： - ）

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();
}

虽然有这个以前的做法，值得指出的一个缺陷。因为我们使用的 UTF-16 头=htt​​p://msdn.microsoft.com/en-us/library/system.io.stringwriter的.aspx> StringWriter的，所以它不是完全等同于你的代码。要获得 UTF-8 头，我们应该使用的的MemoryStream 和的XmlWriter 这是一个额外的行代码：

Although there's a flaw with this previous approach that's worth pointing out. It will generate an utf-16 header as we use StringWriter so it is not exactly equivalent to your code. To get utf-8 header we should use a MemoryStream and an XmlWriter which is an additional line of code:

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());
    }
}
