问题
I have this bit of code, which serializes an object to a file. I'm trying to get each XML attribute to output on a separate line. The code looks like this:
public static void ToXMLFile(Object obj, string filePath)
{
XmlSerializer serializer = new XmlSerializer(obj.GetType());
XmlWriterSettings settings = new XmlWriterSettings();
settings.NewLineOnAttributes = true;
XmlTextWriter writer = new XmlTextWriter(filePath, Encoding.UTF8);
writer.Settings = settings; // Fails here. Property is read only.
using (Stream baseStream = writer.BaseStream)
{
serializer.Serialize(writer, obj);
}
}
The only problem is, the Settings
property of the XmlTextWriter
object is read-only.
How do I set the Settings
property on the XmlTextWriter
object, so that the NewLineOnAttributes
setting will work?
Well, I thought I needed an XmlTextWriter
, since XmlWriter
is an abstract
class. Kinda confusing if you ask me. Final working code is here:
/// <summary>
/// Serializes an object to an XML file; writes each XML attribute to a new line.
/// </summary>
public static void ToXMLFile(Object obj, string filePath)
{
XmlSerializer serializer = new XmlSerializer(obj.GetType());
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
settings.NewLineOnAttributes = true;
using (XmlWriter writer = XmlWriter.Create(filePath, settings))
{
serializer.Serialize(writer, obj);
}
}
回答1:
Use the static Create()
method of XmlWriter
.
XmlWriter.Create(filePath, settings);
Note that you can set the NewLineOnAttributes
property in the settings.

I know the question is old, anyway it's actually possible to set indentation for the XMLTextWriter
. Unlike with the XMLwriter
, you don't have to pass through the settings; you should use the Formatting
property:
XmlTextWriter writer = new XmlTextWriter(filePath, Encoding.UTF8);
w.Formatting = Formatting.Indented;
