在c＃中打印printdocument中的更多页面 [英] Printing more pages in printdocument in c#

问题描述

我希望在打印项目增加时打印多张图像。我曾经用ex打印项目。

I want to print multiple image when print items are increasing. I used to print item by using ex.

graphic.DrawString("Name of the client/organization", new Font("Courier New", 11, FontStyle.Bold), new SolidBrush(Color.Black), startX + 40, startY + 70);
graphic.DrawString(": " + NameofClient.Text, new Font("Courier New", 11), new SolidBrush(Color.Black), startX + 370, startY + 70);

此处所有项目（查看图片）只需使用graphic.drawsting打印字符串。我只想要菜单项增加跳到第二页



我尝试过：



我尝试使用e.HasMorePages = true但是在打印时它会计算无穷大。



我想知道什么是更好的方法打印多页。

here all the items(see the image ) just print string using graphic.drawsting. i want only if menu items increase jump in to the second page

What I have tried:

and I try with the e.HasMorePages = true but it count infinity when printing.

I want to know what is the better way to print multiple page.

推荐答案

请参阅我对该问题的评论。显而易见的是，硬编码的立即常数不能用于确定打印效果。当你需要更多页面时，它应该是真的，最终它应该变成错误。我不知道还有什么需要解释。



请参阅：

PrintPageEventArgs Class（System.Drawing.Printing） [ ^ ]，
PrintPageEventArgs.HasMorePages Property （System.Drawing.Printing） [ ^ ]。



在您的情况下，多页的情况，右边 - 分配的部分操作数应按以下条件计算：

Please see my comment to the question. It should obvious that having hard-coded immediate constant true cannot work to finilize printing. When you need more pages, it should be true, and eventually it should become false. I don't know what else needs explanation.

Please see:
PrintPageEventArgs Class (System.Drawing.Printing)[^],
PrintPageEventArgs.HasMorePages Property (System.Drawing.Printing)[^].

In your case, the case of multiple pages, the right-part operand of assignement should be calculated on condition:

void myPrintPageHandler(object sender, PrintPageEventArgs ev) {
   // ...
   ev.HasMorePages = !AllPagesArePrinted(ev);
   // where the function AllPagesArePrinted(ev) is on your, it depends on your logic
}
