Only way I know of is like this.
我所知道的唯一方法是这样。
iTextSharp.text.Rectangle rec = new iTextSharp.text.Rectangle(pageWidth, pageHeight);
Document doc = new Document(rec);
doc.SetMargins(0f, 0f, 0f, 0f);
However, this will limit margins too
但是，这也会限制利润率

You can do it all in one line.
您可以在一行中完成所有操作。
Document doc = new Document(PageSize.LETTER, 0f, 0f, 0f, 0f );

setMaring Impelemented as
setMaring 引入为
public override bool SetMargins(float marginLeft, float marginRight, float marginTop, float marginBottom)
{
if ((this.writer != null) && this.writer.IsPaused())
{
return false;
}
this.nextMarginLeft = marginLeft;
this.nextMarginRight = marginRight;
this.nextMarginTop = marginTop;
this.nextMarginBottom = marginBottom;
return true;
}
therefor margin applied for next page. for solve this problem after open pdfDocument call newPage() this solution work for empty pdfDocument .
因此为下一页申请了保证金。为了在打开 pdfDocument 调用 newPage() 后解决此问题，此解决方案适用于空 pdfDocument 。
using (FileStream msReport = new FileStream(pdfPath, FileMode.Create))
{
using (Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 10f))
{
try
{
//open the stream
pdfDoc.Open();
pdfDoc.setMargin(20f, 20f, 20f, 20f);
pdfDoc.NewPage();
pdfDoc.Close();
}
catch (Exception ex)
{
//handle exception
}
finally
{
}
}
}
