Removing version from xml file

问题

I am creating a Xml like format using XmlWriter. But in the output there is version information also.

<?xml version="1.0" encoding="utf-8"?>

I don't need this in my file. How can I do that? Is there any way to remove it by code?

回答1:

Use the ConformanceLevel and OmitXmlDeclaration properties. Example:

XmlWriter w;
w.Settings = new XmlWriterSettings();
w.Settings.ConformanceLevel = ConformanceLevel.Fragment;
w.Settings.OmitXmlDeclaration = true;

回答2:

When creating your XmlWriter, pass through the settings you want using XmlWriterSettings:

XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;

writer = XmlWriter.Create(Console.Out, settings);

XmlWriterSettings has other properties as well (indent and more).

You can use

XmlWriterSettings class

and use XmlWriterSettings.OmitXmlDeclaration Property
