将XDocument转换为Stream

Question

如何将XDocument中的XML转换为MemoryStream，而不将任何内容保存到磁盘？

Answer 1

在.NET 4及更高版本中，您可以将其保存到MemoryStream：

Stream stream = new MemoryStream();
doc.Save(stream);
// Rewind the stream ready to read from it elsewhere
stream.Position = 0;

在.NET 3.5及更早版本中，您需要根据XmlWriter创建MemoryStream并保存到该{{1}}，如dtb's answer所示。

Answer 2

查看XDocument.WriteTo方法; e.g：

using (MemoryStream ms = new MemoryStream())
{
    XmlWriterSettings xws = new XmlWriterSettings();
    xws.OmitXmlDeclaration = true;
    xws.Indent = true;

    using (XmlWriter xw = XmlWriter.Create(ms, xws))
    {
        XDocument doc = new XDocument(
            new XElement("Child",
                new XElement("GrandChild", "some content")
            )
        );
        doc.WriteTo(xw);
    }
}

Answer 3

XDocument doc = new XDocument(
    new XElement(C_ROOT,
        new XElement("Child")));
using (var stream = new MemoryStream())
{
    doc.Save(stream);
    stream.Seek(0, SeekOrigin.Begin);
}
