I have a PDF generation code which was previously downloaded in Portait mode and the code behind is shown below.
我有一个PDF生成代码，以前是以Portait模式下载的，后面的代码如下所示。
Document doc = new Document(PageSize.A4, 88f, 88f, 10f, 10f);
which was working properly.
哪个工作正常。
Now I need the same PDF to be converted to Landscape mode, I googled it and found this code.
现在我需要将相同的PDF转换为横向模式，我用Google搜索并找到此代码。
Document doc = new Document(new Rectangle(288f, 144f), 10, 10, 10, 10);
doc.SetPageSize(iTextSharp.text.PageSize.A4.Rotate());
But still its displaying in Portrait mode.Any help appreciated.
但仍然以纵向模式显示。任何帮助赞赏。

You use
你用
Document doc = new Document(PageSize.A4, 88f, 88f, 10f, 10f);
for portrait PDF. The PageSize.A4 is defined as
用于肖像PDF。 PageSize.A4定义为
Rectangle A4 = new RectangleReadOnly(595,842);
Thus, one way to create a landscape PDF would be to use a RectangleReadOnly with switched width and height values:
因此，创建横向PDF的一种方法是使用具有切换宽度和高度值的RectangleReadOnly：
Document doc = new Document(new RectangleReadOnly(842,595), 88f, 88f, 10f, 10f);
Alternatively a rotated version of the original rectangle should work, too:
或者，原始矩形的旋转版本也应该起作用：
Document doc = new Document(new RectangleReadOnly(595,842,90), 88f, 88f, 10f, 10f);

maybe the problem is when you are giving it 10,10,10,10. how can you see it as landscape?? change it to as per you margins and try this link
也许问题是当你给它10,10,10,10时。你怎么能把它看作风景？将其更改为您的边距并尝试此链接
