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
