how to save xmldocument to a stream
提问by user1711383
I've already written code to parse my xml file with an XmlReaderso I don't want to rewrite it. I've now added encryption to the program. I have encrypt() and decrypt() functions which take an xml document and the encryption algorithm. I have a function that uses an xml reader to parse the file but now with the xml document I'm not sure how to create the xmlreader.
我已经编写了代码来解析我的 xml 文件，XmlReader所以我不想重写它。我现在已经为程序添加了加密。我有使用 xml 文档和加密算法的 encrypt() 和decrypt() 函数。我有一个使用 xml 读取器来解析文件的函数，但现在使用 xml 文档我不确定如何创建 xmlreader。
The question is how to save my xml document to a stream. I'm sure it's simple but I don't know anything about streams.
问题是如何将我的 xml 文档保存到流中。我确定这很简单，但我对流一无所知。
XmlDocument doc = new XmlDocument();
doc.PreserveWhitespace = true;
doc.Load(filep);
Decrypt(doc, key);
Stream tempStream = null;
doc.Save(tempStream); // <--- the problem is here I think
using (XmlReader reader = XmlReader.Create(tempStream))
{
while (reader.Read())
{ parsing code....... } }

You can try with MemoryStreamclass
你可以试试MemoryStream上课
XmlDocument xmlDoc = new XmlDocument( );
MemoryStream xmlStream = new MemoryStream( );
xmlDoc.Save( xmlStream );
xmlStream.Flush();//Adjust this if you want read your data
xmlStream.Position = 0;
//Define here your reading

Writing to a file:
写入文件：
static void Main(string[] args)
{
XmlDocument doc = new XmlDocument();
doc.LoadXml("<FTPSessionOptionInfo><HostName>ftp.badboymedia.ca</HostName></FTPSessionOptionInfo>");
using (StreamWriter fs = new StreamWriter("test.xml"))
{
fs.Write(doc.InnerXml);
}
}

try this
尝试这个
XmlDocument document= new XmlDocument( );
string pathTmp = "d:\somepath";
using( FileStream fs = new FileStream( pathTmp, FileMode.CreateNew ))
{
document.Save(pathTmp);
fs.Flush();
}

I realize this is an old question, but thought it worth adding a method from this nice little blog post. This edges out some less performant methods.
我意识到这是一个老问题，但认为值得从这篇漂亮的小博文中添加一个方法。这淘汰了一些性能较差的方法。
private static XDocument DocumentToXDocumentReader(XmlDocument doc)
{
return XDocument.Load(new XmlNodeReader(doc));
}
