What's the correct way to add a PageContent/ FixedPage to a FixedDocument in WPF?
提问by nicodemus13
In WPF, in order to add a FixedPageto a FixedDocumentin code one needs to:
在WPF中，以添加FixedPage到FixedDocument代码中的一个需求：
var page = new FixedPage();
var pageContent = new PageContent();
((IAddChild)pageContent).AddChild(page);
This appears to be the only way, however:
然而，这似乎是唯一的方法：
The MSDN documentation explicitly says one shouldn't do this ('This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.'- PageContent.IAddChild.AddChild Method).
It's ugly to have to cast to an explicit interface implementation in order to add the content to
PageContent.It's not simple to perform the basic operation of
PageContent.
MSDN 文档明确指出不应这样做（“此 API 支持 .NET Framework 基础结构，不应直接从您的代码中使用。”- PageContent.IAddChild.AddChild Method）。
为了将内容添加到
PageContent.执行 的基本操作并不简单
PageContent。
The documentation doesn't actually explain how to do this and I couldn't find any other information on how to do it. Is there another way? A 'correct' way?
该文档实际上并未解释如何执行此操作，我找不到有关如何执行此操作的任何其他信息。还有其他方法吗？“正确”的方式？

According to MSDN documentation, you simply add a FixedPageobject to the PageContent.Childproperty and then add that to the FixedDocumentby calling the FixedDocument.Pages.Addmethod.
根据 MSDN 文档，您只需将FixedPage对象添加到PageContent.Child属性，然后FixedDocument通过调用 FixedDocument.Pages.Add方法将其添加到。
For instance:
例如：
public FixedDocument RenderDocument()
{
FixedDocument fd = new FixedDocument();
PageContent pc = new PageContent();
FixedPage fp = new FixedPage();
TextBlock tb = new TextBlock();
//add some text to a TextBox object
tb.Text = "This is some test text";
//add the text box to the FixedPage
fp.Children.Add(tb);
//add the FixedPage to the PageContent
pc.Child = fp;
//add the PageContent to the FixedDocument
fd.Pages.Add(pc);
return fd;
}
