How to create an XML file in VB.NET using Dataset
By: Issac in VB.net Tutorials on 2009-02-21
We can create XML in several ways; we need a text editor to write a XML file, it is a tag based language that means the document is made up of XML tags that contain information.
Here we are going to create an XML file Product.XML using an ADO.NET Dataset. For that we have to manually create a Datatable first and add the data of Product.XML in the Datatable. Then add the Datatable in a Dataset. Call the method WriteXml of Dataset and pass the file name Product.XML as argument.
Imports System.Xml
Imports System.Data
Public Class Form1
Dim dt As DataTable
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim ds As New DataSet
dt = New DataTable()
dt.Columns.Add(New DataColumn("Product_ID", Type.GetType("System.Int32")))
dt.Columns.Add(New DataColumn("Product_Name", Type.GetType("System.String")))
dt.Columns.Add(New DataColumn("product_Price", Type.GetType("System.Int32")))
fillRows(1, "product1", 1111)
fillRows(2, "product2", 2222)
fillRows(3, "product3", 3333)
fillRows(4, "product4", 4444)
ds.Tables.Add(dt)
ds.Tables(0).TableName = "product"
ds.WriteXml("Product.xml")
MsgBox("Done")
End Sub
Private Sub fillRows(ByVal pID As Integer, ByVal pName As String, ByVal pPrice As Integer)
Dim dr As DataRow
dr = dt.NewRow()
dr("Product_ID") = pID
dr("Product_Name") = pName
dr("product_Price") = pPrice
dt.Rows.Add(dr)
End Sub
End Class
