本文介绍了PDFsharp - 如何创建第2页的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我找不到PDFsharp文档说明了如何使用C＃添加第2页！
作为一个例子，比VB6我使用PDF创建方法所谓mjwPDF。为了表明该页面已完成
objPDF.PDFEndPage
和开始一个新的页面：
objPDF.PDFNewPage
我PDFsharp初始设置：
//创建一个新的PDF文档
PdfDocument文档=新PdfDocument（）;
//创建一个空白页
PdfPage页= document.AddPage（）;
//page.Contents.CreateSingleContent().Stream.UnfilteredValue;
//获取绘图
XGraphics GFX = XGraphics.FromPdfPage（页）的XGraphics对象;
不幸的是PDFsharp我无法找出如何在新页面上开始/写。我看到这些命令，但不能获得第二页开始
document.AddPage（）;
document.InsertPage（）;
我已经试过这两个，但我的产量继续第1页，而不是2页上写字。
任何想法，将不胜感激。

解决方案
您创建
document.AddPage一个新的页面（）;
，然后调用
XGraphics.FromPdfPage（页）;
获得第二页GFX对象（可能这就是失踪的步骤）。
因此，重复上述步骤，从您的代码示例为每一个新页面：
/ /创建一个空白页
PdfPage页= document.AddPage（）;
//获取绘图
XGraphics GFX = XGraphics.FromPdfPage（页）的XGraphics对象;
更新：在你的循环，你做到以下几点：
document.AddPage（）;
XGraphics.FromPdfPage（页）;
AddPage（）返回一个处理到新创建的页面 - 你扔进了垃圾箱。
然后调用XGraphics.FromPdfPage（）创建另一个GFX第一页 - 这你也扔在垃圾桶，但你会得到一个异常，因为已经有第一页一个GFX
一个小的变化应该做的伎俩：
页=文档。 AddPage（）;
GFX = XGraphics.FromPdfPage（页）;
另请参阅：

我做梦也没想到添加第二个页面会如此艰难！与建议的代码没有运气。结果
PDFsharp包括相当多的工作样本，让人们去。没有运气，因为你忽略的重要组成部分，建议代码 - 由方法返回的值
I can't find documentation in PDFsharp to show how to add a 2nd page using C#!
As an example, over in VB6 I use a PDF creation method called mjwPDF. To indicate that the page is finished
objPDF.PDFEndPage
And to start a new page:
objPDF.PDFNewPage
My PDFsharp initial settings:
// Create a new PDF document
PdfDocument document = new PdfDocument();
// Create an empty page
PdfPage page = document.AddPage();
//page.Contents.CreateSingleContent().Stream.UnfilteredValue;
// Get an XGraphics object for drawing
XGraphics gfx = XGraphics.FromPdfPage(page);
Unfortunately in PDFsharp I can't find out how to start/write on a new page. I see these commands but can't get a second page started.
document.AddPage();
document.InsertPage();
I've tried both of these but my output continues to write on page 1, not page 2.
Any ideas would be greatly appreciated.

解决方案
You create a new page with
document.AddPage();
and then call
XGraphics.FromPdfPage(page);
to get a gfx object for the second page (probably this is the missing step).
So repeat those steps from your code sample for every new page:
// Create an empty page
PdfPage page = document.AddPage();
// Get an XGraphics object for drawing
XGraphics gfx = XGraphics.FromPdfPage(page);
Update: In your loop you do the following:
document.AddPage();
XGraphics.FromPdfPage(page);
AddPage() returns a "handle" to the newly created page - which you throw in the bin.Then you call "XGraphics.FromPdfPage()" to create yet another gfx for the first page - which you also would throw in the bin, but you get an exception since there already is a gfx for the first page.
A small change should do the trick:
page = document.AddPage();
gfx = XGraphics.FromPdfPage(page);

"I never dreamed adding a second page could be so difficult! No luck with the suggested code."
PDFsharp includes quite a few working samples to get people going. No luck with the suggested code since you ignored the important part - the values returned by the methods.
