I have two PDF documents and I want to find out if each page of one PDF is contained in the other PDF. I tried using the C# code below but it is using a Reference Comparison for the Equals method, and I need a Value Comparison. I am not sure how to go about this.

protected Boolean ExistingPdfContainsNewPdf(PdfDocument existingPdf, PdfDocument newPdf)
{
Boolean pageFound = false;
foreach (PdfPage newPage in newPdf.Pages)
{
foreach (PdfPage existingPage in existingPdf.Pages)
{
if (newPage.Equals(existingPage))
{
pageFound = true;
break;
}
pageFound = false;
}
}
return pageFound;
}

Thank you very much.
