如何在c#codebehind中将PrintPriviewDialog paperize设置为a5？

Question

我有一个Windows窗体应用程序,一个简单的窗体,包含一个面板.我已将面板大小设置为:560,579像素,我已按此方式设置打印文档大小:

System.Drawing.Printing.PaperSize a = new System.Drawing.Printing.PaperSize("A5 (148 x 210 mm)", 584, 827);
printDocument1.PrinterSettings.DefaultPageSettings.PaperSize = a;

现在我希望printpreviewdialoge页面大小为a5或至少与我的打印文档大小相同并且适合它,我怎么能实现这一点？

    private void printDocument1_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
    {
        Bitmap b = new Bitmap(pnlPrint.Width, pnlPrint.Height);
        pnlPrint.DrawToBitmap(b, new System.Drawing.Rectangle(0, 0, pnlPrint.Width, pnlPrint.Height));
        e.Graphics.DrawImage(b,0,0);
    }

    private void Print()
    {
    PrintPreviewDialog printPreviewDialog1 = new PrintPreviewDialog();
    var paperSize = printDocument1.PrinterSettings.PaperSizes.Cast<PaperSize>().FirstOrDefault(e => e.PaperName == "A5");
    printDocument1.PrinterSettings.DefaultPageSettings.PaperSize = paperSize; 
    printPreviewDialog1.Document = printDocument1;

    printPreviewDialog1.ShowDialog();

    }

Answer 1

您可以从PaperSize对象的PrinterSettings属性中获取A5 PrintDocument对象.它具有PaperSizes保存所选打印机的所有纸张尺寸的属性.您可以使用LINQ找到所需的LINQ.例如:

var paperSize = printDoc.PrinterSettings.PaperSizes.Cast<PaperSize>().FirstOrDefault(e => e.PaperName == "A5");
printDoc.PrinterSettings.DefaultPageSettings.PaperSize = paperSize;
