问题描述

I am editing csproj files with Linq-to-XML and need to save the XML without the <?XML?> header.

由于XDocument.Save（）缺少必要的选择，什么是做到这一点的最好方法是什么？

As XDocument.Save() is missing the necessary option, what's the best way to do this?

推荐答案

您可以用 XmlWriterSettings 做到这一点，并且文档保存到一个的XmlWriter ：

You can do this with XmlWriterSettings, and saving the document to an XmlWriter:

XDocument doc = new XDocument(new XElement("foo",
    new XAttribute("hello","world")));

XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
StringWriter sw = new StringWriter();
using (XmlWriter xw = XmlWriter.Create(sw, settings))
// or to write to a file...
//using (XmlWriter xw = XmlWriter.Create(filePath, settings))
{
    doc.Save(xw);
}
string s = sw.ToString();
