示例1: New

Public Sub New(ByVal virtualDir As String, ByVal provider As SamplePathProvider)
  MyBase.New(virtualDir)
  spp = provider
  GetData()
End Sub

Protected Sub GetData()
  ' Get the data from the SamplePathProvider.
  Dim spp As SamplePathProvider
  spp = CType(HostingEnvironment.VirtualPathProvider, SamplePathProvider)

  Dim ds As DataSet
  ds = spp.GetVirtualData

  ' Clean up the path to match data in resource file.
  Dim path As String
  path = VirtualPath.Replace(HostingEnvironment.ApplicationVirtualPath, "")
  Dim trimChars() As Char = {"/"c}
  path = path.TrimEnd(trimChars)

  ' Get the virtual directory from the resource table.
  Dim dirs As DataTable
  dirs = ds.Tables("resource")
  Dim rows As DataRow()
  rows = dirs.Select( _
    String.Format("(name = '{0}') AND (type='dir')", path))

  ' If the select returned a row, the directory exits.
  If (rows.Length > 0) Then
    existsValue = True

    ' Get the children from the resource table.
    ' This technique works for small numbers of virtual resources.
    '  Sites with moderate to large numbers of virtual
    '  resources should choose a method that consumes fewer
    '  computer resources.
    Dim childRows As DataRow()
    childRows = dirs.Select( _
      String.Format("parentPath = '{0}'", path))

    For Each childRow As DataRow In childRows
      Dim childPath As String
      childPath = CType(childRow("path"), String)

      If (childRow("type").ToString = "dir") Then
        Dim svd As New SampleVirtualDirectory(childPath, spp)
        childrenValue.Add(svd)
        directoriesValue.Add(svd)
      Else
        Dim svf As New SampleVirtualFile(childPath, spp)
        childrenValue.Add(svf)
        directoriesValue.Add(svf)
      End If
    Next

  End If
End Sub
