System.IO.File.WriteAllText("C:\我的文件夾\我的文件.xml", s)

你也可以把內容放進textbox中,然后把textbox的內容寫進去:

System.IO.File.WriteAllText("C:\我的文件夾\我的文件.xml", textbox1.text)

vb.net中怎么創建xml文件并寫數據

DataSet 和 DataTable都有現成的方法：WriteXml

DataTable tb = this.dataGridView1.DataSource as DataTable;

if(tb != null)

{

tb.WriteXml(@"C:\table.xml",true);

return;

}

DataView dv = this.dataGridView1.DataSource as DataView;

if(dv != null)

{

dv.Table.WriteXml(@"C:\table.xml",true);

return;

}

IList list = this.dataGridView1.DataSource as IList;

if(list != null)

{

//to do,如果是IList,就要你自己想辦法導出了

//XmlDocument or XmlWriter都可以考慮

}

vb.net操作xml數據庫(急)

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("此文件表示書店庫存數據庫的另一個片斷")

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()

'向文件寫 XML 并關閉編寫器

myXmlTextWriter.Flush()

myXmlTextWriter.Close()

' 讀取返回的文件并進行分析以確保正確生成 XML

myXmlTextReader = new XmlTextReader (args)

FormatXml (myXmlTextReader, args)

catch e as Exception

Console.WriteLine ("異常：{0}", e.ToString())

finally

Console.WriteLine()

Console.WriteLine("對文件 {0} 的處理已完成。", args)

If Not myXmlTextReader Is Nothing

myXmlTextReader.Close()

end if

'關閉編寫器

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

case XmlNodeType.DocumentType:

Format (reader, "DocumentType")

docCount += 1

case XmlNodeType.Comment:

Format (reader, "Comment")

commentCount += 1

case XmlNodeType.Element:

Format (reader, "Element")

elementCount += 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

' 顯示該文件的統計信息

Console.WriteLine ()

Console.WriteLine("{0} 文件的統計信息", filename)

Console.WriteLine ()

Console.WriteLine("處理指令：" piCount)

Console.WriteLine("文檔類型：" docCount)

Console.WriteLine("注釋：" commentCount)

Console.WriteLine("元素：" elementCount)

Console.WriteLine("屬性：" attributeCount)

Console.WriteLine("文本：" textCount)

Console.WriteLine("空白：" whitespaceCount)

End Sub

private shared Sub Format(byref reader as XmlTextReader , NodeType as String)

' 格式化輸出

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

如何對Vb.net進行漂亮的XML注釋

在緊挨著類或成員的上一行打三個單引號，自動生成XML注釋。

你可以使用para來換行。

使用see cref來標明參考項。

vb.net XML文件如何寫入

Imports System.IO

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim f As New FileInfo("d:\doc.xml")

If f.Exists = False Then

f.Create()

f.Refresh()

End If

Dim s As String = ""

Dim sw As StreamWriter = f.CreateText()

s = "?xml version=""1.0"" encoding=""GB2312""?"

sw.WriteLine(s)

sw.WriteLine("doc")

sw.WriteLine(" assembly")

sw.WriteLine("userId34/userId")

sw.WriteLine("userName張三/userName")

sw.WriteLine("qxbz1/qxbz")

sw.WriteLine(" /assembly")

sw.WriteLine("/doc")

sw.Flush()

sw.Close()

Process.Start("d:\doc.xml")

End Sub

End Class
