DataSet to XML (набор данных wpf)

0 голосов
/ 01 октября 2019

Я создал набор данных во время разработки в Project-> Add New Items-> Settings.xsd. Затем я создал две таблицы данных с именами LANSettings и WANSettings, со столбцами для IP-адреса и тому подобное. Я получил идею при использовании форм Windows. К сожалению, когда дело доходит до wpf, реализация немного отличается. Я пытался выучить набор данных в xml, и я могу его создать, но именно тогда набор данных создается в коде позади.

Я пытался выучить набор данных и xml в Интернете, но все, что они показывают, относится к языку c #. Как я могу сделать это при использовании набора данных во время разработки?

вот неполный код:

MainWindow.xaml.vb 

Imports System.Xml
Imports System.Data
Imports datasettrials


Class MainWindow
    Private Sub Window_Loaded(sender As Object, e As RoutedEventArgs) Handles MyBase.Loaded

        Dim Settings As datasettrials.Settings = CType(Me.FindResource("Settings"), datasettrials.Settings)
    End Sub

    Private Sub ApplyButton_Click(sender As Object, e As RoutedEventArgs) Handles ApplyButton.Click

    End Sub

    Private Sub WriteXmlToFile(thisDataSet As Settings)
        If thisDataSet Is Nothing Then
            Return
        End If

        Dim filename As String = "xmlSettings.xml"

        Dim stream As New System.IO.FileStream(filename, System.IO.FileMode.Create)

        Dim xmlwriter As New XmlTextWriter(stream, System.Text.Encoding.Unicode)

        thisDataSet.WriteXml(xmlwriter)
        xmlwriter.Close()

    End Sub
End Class
