使用System.XML
Imports Microsoft.VisualBasic
Imports System
Imports System.IO
Imports System.Xml
namespace HowTo.Samples.XML
public class WriteXmlFileSample
private const document as string = "newbooks.xml"
shared sub Main()
Dim myWriteXmlFileSample as WriteXmlFileSample
myWriteXmlFileSample = new WriteXmlFileSample()
myWriteXmlFileSample.Run(document)
end sub
public sub Run(args As String)
Dim myXmlTextReader as XmlTextReader = nothing
Dim myXmlTextWriter as XmlTextWriter = nothing
try
myXmlTextWriter = new XmlTextWriter (args, nothing)
myXmlTextWriter.Formatting = System.Xml.Formatting.Indented
myXmlTextWriter.WriteStartDocument(false)
myXmlTextWriter.WriteDocType("bookstore", nothing, "books.dtd", nothing)
myXmlTextWriter.WriteComment("此文件表示书店库存数据库的另一个片断")
myXmlTextWriter.WriteStartElement("bookstore")
myXmlTextWriter.WriteStartElement("book", nothing)
myXmlTextWriter.WriteAttributeString("genre","autobiography")
myXmlTextWriter.WriteAttributeString("publicationdate","1979")
myXmlTextWriter.WriteAttributeString("ISBN","0-7356-0562-9")
myXmlTextWriter.WriteElementString("title", nothing, "The Autobiography of Mark Twain")
myXmlTextWriter.WriteStartElement("Author", nothing)
myXmlTextWriter.WriteElementString("first-name", "Mark")
myXmlTextWriter.WriteElementString("last-name", "Twain")
myXmlTextWriter.WriteEndElement()
myXmlTextWriter.WriteElementString("price", "7.99")
myXmlTextWriter.WriteEndElement()
myXmlTextWriter.WriteEndElement()
'向文件写 XML 并关闭编写器
myXmlTextWriter.Flush()
myXmlTextWriter.Close()
' 读取返回的文件并进行分析以确保正确生成 XML
myXmlTextReader = new XmlTextReader (args)
FormatXml (myXmlTextReader, args)
catch e as Exception
Console.WriteLine ("异常：{0}", e.ToString())
finally
Console.WriteLine()
Console.WriteLine("对文件 {0} 的处理已完成。", args)
If Not myXmlTextReader Is Nothing
myXmlTextReader.Close()
end if
'关闭编写器
If Not myXmlTextWriter Is Nothing
myXmlTextWriter.Close()
end if
End try
End Sub
private shared Sub FormatXml (reader as XmlTextReader, filename as String)
Dim piCount, docCount, commentCount, elementCount as Integer
Dim attributeCount, textCount, whitespaceCount as Integer
While reader.Read()
Select (reader.NodeType)
case XmlNodeType.ProcessingInstruction:
Format (reader, "ProcessingInstruction")
piCount += 1

While reader.MoveToNextAttribute()
Format (reader, "Attribute")
end While
if (reader.HasAttributes)
attributeCount += reader.AttributeCount
end if
case XmlNodeType.Text:
Format (reader, "Text")
textCount += 1
case XmlNodeType.Whitespace:
whitespaceCount += 1
End Select
End While
' 显示该文件的统计信息
Console.WriteLine ()
Console.WriteLine("{0} 文件的统计信息", filename)
Console.WriteLine ()
Console.WriteLine("处理指令：" & piCount)
Console.WriteLine("文档类型：" & docCount)
Console.WriteLine("注释：" & commentCount)
Console.WriteLine("元素：" & elementCount)
Console.WriteLine("属性：" & attributeCount)
Console.WriteLine("文本：" & textCount)
Console.WriteLine("空白：" & whitespaceCount)
End Sub
private shared Sub Format(byref reader as XmlTextReader , NodeType as String)
' 格式化输出
Console.Write(reader.Depth & " ")
Console.Write(reader.AttributeCount & " ")
Dim i as Integer
for i = 0 to reader.Depth - 1
Console.Write(Strings.chr(9))
Next
Console.Write(reader.Prefix & NodeType & "<" & reader.Name & ">" & reader.Value)
Console.WriteLine()
End Sub
End Class
End Namespace

不明白你的意思。
.net里任何语言都没有自己的功能类库，都是.netSDK提供的，操作xml，.netSDK提供了很多类，自己看看帮助吧 |
