c# – 设置纸张尺寸

请帮我说说如何用c#代码设置我的纸张尺寸.我正在使用API​​ printDocument.

以下是我的代码：

ppvw = new PrintPreviewDialog();
 ppvw.Document = printDoc;
 ppvw.PrintPreviewControl.StartPage = 0;
 ppvw.PrintPreviewControl.Zoom = 1.0;
 ppvw.PrintPreviewControl.Columns = 10;


 // Showing the Print Preview Page
 printDoc.BeginPrint += new System.Drawing.Printing.PrintEventHandler(PrintDoc_BeginPrint);
 printDoc.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(PrintDoc_PrintPage);


 if (ppvw.ShowDialog() != DialogResult.OK)
 {
     printDoc.BeginPrint -= new System.Drawing.Printing.PrintEventHandler(PrintDoc_BeginPrint);
     printDoc.PrintPage -= new System.Drawing.Printing.PrintPageEventHandler(PrintDoc_PrintPage);
 }


 printDoc.PrinterSettings.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("a2",5.0,5.0);
 printDoc.Print();

解决方法

PrinterSettings ps = new PrinterSettings();
PrintDocument recordDoc = new PrintDocument();
recordDoc.PrinterSettings = ps;

这是一种通过类似’A4’设置纸张尺寸的方法

IEnumerable<PaperSize> paperSizes = ps.PaperSizes.Cast<PaperSize>();
PaperSize sizeA4 = paperSizes.First<PaperSize>(size => size.Kind == PaperKind.A4); // setting paper size to A4 size
recordDoc.DefaultPageSettings.PaperSize = sizeA4;

这是另一种设置自定义纸张尺寸的方法

recordDoc.DefaultPageSettings.PaperSize = new PaperSize("210 x 297 mm",800,800);
PrintPreviewDialog ppvw = new PrintPreviewDialog();
ppvw .Document = recordDoc;
ppvw.ShowDialog();

希望它有效.
