急急急！有关在.net 中创建一个新的xml文件

[Brune]

Dim mydom As New Xml.XmlDocument()
Dim GetFeature, As Xml.XmlElement
GetFeature = mydom.CreateElement("GetFeature")
GetFeature.SetAttribute("version", "1.0.0")
GetFeature.SetAttribute("service", "WFS")
GetFeature.SetAttribute("xmlns", "http://www.opengis.net/wfs")
GetFeature.SetAttribute("xmlns:ogc", "http://www.opengis.net/ogc")
mydom.Save("c:\filter.xml")
请问为什么写出的xml文件没有头 <?xml version="1.0" ?> 怎样加上去？？

[待接入自我]

Dim newDec As XmlDeclaration
newDec = doc.CreateXmlDeclaration("1.0", Nothing, Nothing)
doc.AppendChild(newDec)

因此，你的完整代码应该是
dim mydom as new xml.xmldocument()
Dim GetFeature, As Xml.XmlElement
Dim newDec As XmlDeclaration

newDec = mydom.CreateXmlDeclaration("1.0", Nothing, Nothing)
mydom.AppendChild(newDec)

GetFeature = mydom.CreateElement("GetFeature")
GetFeature.SetAttribute("version", "1.0.0")
GetFeature.SetAttribute("service", "WFS")
GetFeature.SetAttribute("xmlns", "http://www.opengis.net/wfs")
GetFeature.SetAttribute("xmlns:ogc", "http://www.opengis.net/ogc")
mydom.AppendChild(GetFeature)
mydom.Save("c:\filter.xml")
