How to add a line break when using XmlSerializer

Question

I am wondering how to add a line break for each element when using XmlSerializer?

Sample code:

XmlSerializer serializer = new XmlSerializer(typeof(xxx));
using (XmlWriter xmlWriter = XmlWriter.Create("test.xml")
{
    serializer.Serialize(xmlWriter, xxx);
}

Answer 1

You can use XmlWriterSettings and set the properties to out the indentation and newlines. .Indent and .NewLineOnAttributes seem to be what you would want.

When creating the XmlWriter, pass in an XmlWriterSettings object with Indent set to true.

var xmlWriterSettings = new XmlWriterSettings() { Indent = true };
XmlSerializer serializer = new XmlSerializer(typeof(xxx));
using (XmlWriter xmlWriter = XmlWriter.Create("test.xml", xmlWriterSettings)
{
    serializer.Serialize(xmlWriter, xxx);
}
