将XDocument转换为流

Question

如何将XDocument中的XML转换为MemoryStream而不保存任何内容到磁盘？

Answer 1

看看XDocument.WriteTo方法;例如：

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 2

在.NET 4及更高版本，您可以将其保存到一个MemoryStream：

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

在.NET 3.5和更早的版本，你需要创建一个基于MemoryStream一个XmlWriter和除此之外，如dtb's answer所示。

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); 
}
