[英]How to create an XML file from a XmlReader?
How do you write an XML file from an System.Xml.XmlReader? 如何从System.Xml.XmlReader编写XML文件?
I thought this would be a simple question but whenever I search I seem to be ending up with reading the file to a reader or writing node by node. 我认为这将是一个简单的问题,但每当我搜索时,我似乎最终都会将文件读取到读取器或逐个节点地编写。
The XmlReader object conveys xml that was stored in a database and just needs to come out of the database to a file. XmlReader对象传达存储在数据库中的xml,只需要从数据库中传出一个文件即可。 Is there any easy way to do this?
有没有简单的方法来做到这一点?
SqlCommand dataCmd = new SqlCommand(sqlText, Conn);
System.Xml.XmlReader dataReader = null;
dataCmd.CommandTimeout = 60000;
Conn.Open();
dataReader = dataCmd.ExecuteXmlReader();
dataReader.Read();
You need to create an XmlWriter
and call its WriteNode
method . 您需要创建一个
XmlWriter
并调用其WriteNode
方法 。
For example: 例如:
using (conn)
using (SqlCommand dataCmd = new SqlCommand(sqlText, Conn)) {
dataCmd.CommandTimeout = 60000;
Conn.Open();
using (XmlReader dataReader = dataCmd.ExecuteXmlReader())
using (XmlWriter writer = XmlWriter.Create(File.OpenWrite(...)) {
writer.WriteNode(dataReader, true);
}
}
The simplest way would be to pass it into an XmlWriter, using a method such as this: 最简单的方法是将它传递给XmlWriter,使用如下方法:
public void WriteOutXml(XmlReader xmlReader, string fileName)
{
var writer = XmlWriter.Create(fileName);
writer.WriteNode(xmlReader, true);
}
