我正在尝试制作一个可以打印信封（自定义和普通）的应用程序。我设置了要打印的尺寸和页面，但是当我打印或查看打印预览时，页面尺寸仍然相同。基本上，该应用程序是 3 个组合框（0：选择自定义尺寸，1：选择打印机，2：选择进纸器）和按钮“打印”

我错过了什么吗？

PrintDocument pd = new PrintDocument();
PaperSize paperSize;

            g.DrawString(text, fontText, Brushes.Black, new Point(10, 140));

        }

您可以尝试使用此代码更改 printDocument PaperSize ，它可以 100% 工作：

for(int i=0;i<printDocument1.PrinterSettings.PaperSizes.Count; i++)
        { 
            //NASSIM LOUCHANI

            if(printDocument1.PrinterSettings.PaperSizes[i].RawKind == 11)
            {
                printDocument1.DefaultPageSettings.PaperSize = printDocument1.PrinterSettings.PaperSizes[i];
            }
        }

数字 11 是 A5 PaperKind，我想你可以完成其余的。

谢谢你 。
