c# - 从 C# 打印信封

Question

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。我正在设置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;

            String text = "Text font size 10";
            Font fontText = new Font("Times New Roman", 10, FontStyle.Regular);
            g.DrawString(text, fontText, Brushes.Black, new Point(10, 140));

        }

您可以尝试使用此代码来更改 printDocument PaperSize ，它 100% 有效:

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，我想你可以完成剩下的。

谢谢。
