Convert PDF to Base64

How can I convert a PDF to Base64?

The PdfDocument object doesn't contain a property to get Base64 directly, though you can get the byte[] which can be used to get Base64.

using var pdf = new PdfDocument("MyPDF.pdf");
    var ByteArray = pdf.BinaryData;
    var Base64Result= Convert.ToBase64String(ByteArray);

using var pdf = new PdfDocument("MyPDF.pdf");
    var ByteArray = pdf.BinaryData;
    var Base64Result= Convert.ToBase64String(ByteArray);

Dim pdf = New PdfDocument("MyPDF.pdf")
	Dim ByteArray = pdf.BinaryData
	Dim Base64Result= Convert.ToBase64String(ByteArray)
