c# - 使用流文档在 PrintDialog 上设置打印方向

Question

只是想知道是否有办法在使用流文档的打印对话框上设置打印文档方向。

例如

var document = userControl.Content as FlowDocument;
var printDialog = new PrintDialog();
if (printDialog.ShowDialog() == true)
{
    var paginator = ((IDocumentPaginatorSource) document).DocumentPaginator;
    paginator.PageSize = new Size(userControl.Width, userControl.Height);

    //Set Orientation Landscape .....


    printDialog.PrintDocument(paginator, PrintDescription);
}

Answer 1

利用：

printDialog.PrintTicket.PageOrientation = System.Printing.PageOrientation.Landscape;

您需要添加对ReachFramework.dlland System.Printing.dlleach 的引用。
