Exempel

I följande exempel visas hur du sparar och läser in en StrokeCollection. Det här exemplet förutsätter att det finns en InkCanvas som heter inkCanvas1.

private void SaveStrokes_Click(object sender, RoutedEventArgs e)
{
    FileStream fs = null;

    try
    {
        fs = new FileStream(inkFileName, FileMode.Create);
        inkCanvas1.Strokes.Save(fs);
    }
    finally
    {
        if (fs != null)
        {
            fs.Close();
        }
    }
}

Private Sub SaveStrokes_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)

    Dim fs As FileStream = Nothing

    Try
        fs = New FileStream(inkFileName, FileMode.Create)
        inkCanvas1.Strokes.Save(fs)
    Finally
        If Not fs Is Nothing Then
            fs.Close()
        End If
    End Try

End Sub

private void LoadStrokes_Click(object sender, RoutedEventArgs e)
{
    FileStream fs = null;

    if (!File.Exists(inkFileName))
    {
        MessageBox.Show("The file you requested does not exist." +
            " Save the StrokeCollection before loading it.");
        return;
    }

    try
    {
        fs = new FileStream(inkFileName,
            FileMode.Open, FileAccess.Read);
        StrokeCollection strokes = new StrokeCollection(fs);
        inkCanvas1.Strokes = strokes;
    }
    finally
    {
        if (fs != null)
        {
            fs.Close();
        }
    }
}

Private Sub LoadStrokes_Click(ByVal sender As Object, ByVal e As RoutedEventArgs)

    Dim fs As FileStream = Nothing

    If Not File.Exists(inkFileName) Then
        MessageBox.Show("The file you requested does not exist." & _
            " Save the StrokeCollection before loading it.")
        Return
    End If

    Try
        fs = New FileStream(inkFileName, _
            FileMode.Open, FileAccess.Read)
        Dim strokes As StrokeCollection = New StrokeCollection(fs)
        inkCanvas1.Strokes = strokes
    Finally
        If Not fs Is Nothing Then
            fs.Close()
        End If
    End Try
