من از کد زیر برای بایند استفاده می کنم ....
Imports System.Data.SqlClient
Imports System.Data
Imports System.Xml
Partial Class _Default
Inherits System.Web.UI.Page
Public writer As XmlWriter
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
Public Function GetMenuByParentID(ByVal parentId As Integer) As DataTable
Dim dt As New DataTable()
Using con As New SqlConnection("Data Source=.;Initial Catalog=testmenu;User ID=sa;Password=123456789")
con.Open()
Dim cmd As New SqlCommand("select * from TBLMenu where ParentID=@ParentID", con)
cmd.Parameters.AddWithValue("@ParentID", parentId)
Dim da As New SqlDataAdapter(cmd)
da.Fill(dt)
con.Close()
Return dt
End Using
End Function
Public Sub CreateMenu()
writer = XmlWriter.Create(Server.MapPath("Temp\menu.XML"))
writer.WriteStartDocument()
writer.WriteStartElement("Menu")
CreateNodes(0)
writer.WriteEndDocument()
End Sub
Public Sub CreateNodes(ByVal parentId As Integer)
Dim dt As DataTable = GetMenuByParentID(parentId)
For Each dr As DataRow In dt.Rows
writer.WriteStartElement("Node")
writer.WriteStartAttribute("ID")
writer.WriteValue(dr("MenuID").ToString())
writer.WriteEndAttribute()
writer.WriteStartAttribute("Name")
writer.WriteValue(dr("MenuName").ToString())
writer.WriteEndAttribute()
CreateNodes(Convert.ToInt32(dr("MenuID")))
writer.WriteEndElement()
Next
End Sub
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
CreateMenu()
Response.Redirect("~/")
End Sub
End Class
ولی متاسفانه ارور های زیر رو میده
بعضی وقت ها اینو میده
The process cannot access the file 'i:\menu3\Temp\Menu.xml' because it is being used by another process
و بعضی وقت ها هم این ارور
Root element is missing.
دوستان روش بهتری برای ساهت منو سراغ ندارند که حالت Parent داشته باشه (زیر منو)
با تشکر
