blocks|key|1584735|text|正如本杜威所说，XmlWriterSettings就是你所需要的--比如|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1584736|var+ds+=+new+DataContractSerializer(typeof(Foo));

As bendewey says, XmlWriterSettings is what you need - e.g. something like

<pre><code>var ds = new DataContractSerializer(typeof(Foo));

var settings = new XmlWriterSettings { Indent = true };

using (var w = XmlWriter.Create("fooOutput.xml", settings))
 ds.WriteObject(w, someFoos);
</code></pre>

based on the other samples posted here that use XmlWriter, here's a version (from <a href="http://ClipFlair.codeplex.com" rel="nofollow">http://ClipFlair.codeplex.com</a>) that works with streams (and Ionic.Zip library in specific) and also shows how the code is when you don't apply formatting (using conditional compilation - just comment out the #define to make it write unformatted XML)

<pre><code>#define WRITE_FORMATTED_XML

using System.Xml;

namespace ClipFlair.Windows
{

 public partial class BaseWindow : FloatingWindow
 {

 //...

 #if WRITE_FORMATTED_XML
 private static XmlWriterSettings XML_WRITER_SETTINGS = new XmlWriterSettings() { Indent=true, IndentChars=" "};
 #endif

 //...

 public virtual void SaveOptions(ZipFile zip, string zipFolder = "") //THIS IS THE CORE SAVING LOGIC
 {
 if (SavingOptions != null) SavingOptions(this, null); //notify any listeners

 View.Busy = true;
 try
 {
 ZipEntry optionsXML = zip.AddEntry(zipFolder + "/" + View.GetType().FullName + ".options.xml",
 new WriteDelegate((entryName, stream) =&gt;
 {
 DataContractSerializer serializer = new DataContractSerializer(View.GetType()); //assuming current View isn't null
 #if WRITE_FORMATTED_XML
 using (XmlWriter writer = XmlWriter.Create(stream, XML_WRITER_SETTINGS))
 serializer.WriteObject(writer, View);
 #else
 serializer.WriteObject(stream, View);
 #endif
 }));
 }
 catch (Exception e)
 {
 MessageBox.Show("ClipFlair options save failed: " + e.Message); //TODO: find the parent window
 }
 finally
 {
 View.Busy = false; //in any case (error or not) clear the Busy flag
 }

 if (SavedOptions != null) SavedOptions(this, null); //notify any listeners
 }

 //...

 }

}

Is there an easy way to get DataContractSerializer to spit out formatted XML rather then one long string? I don't want to change the tags or content in any way, just have it add line breaks and indentation to make the XML more readable?

<pre><code>&lt;tagA&gt;
 &lt;tagB&gt;This is&lt;/tagB&gt; 
 &lt;tagC&gt;Much&lt;/tagC&gt;
 &lt;tagD&gt;
 &lt;tagE&gt;easier to read&lt;/tagE&gt;
 &lt;/tagD&gt;
&lt;/tagA&gt;


&lt;tagA&gt;&lt;tagB&gt;This is&lt;/tagB&gt;&lt;tagC&gt;Much&lt;/tagC&gt;&lt;tagD&gt;&lt;tagE&gt;harder to read&lt;/tagE&gt;&lt;/tagD&gt;&lt;/tagA&gt;
</code></pre>

Formatting of XML created by DataContractSerializer

Windows

Ionic

有没有一种简单的方法可以让DataContractSerializer输出格式化的XML而不是一个长字符串？我不想以任何方式更改标记或内容，只想让它添加换行符和缩进，以使XML更具可读性？<tagA> <tagB>This is</tagB> <tagC>Much</tagC> <tagD> ...
