Websupergoo ABCPDF.NET - 在调用 doc.Read() 之前检查 pdf 是否加密/密码保护

Question

doc.Read(filePath) will error out if the pdf file is encrypted and a password is not passed. I haven't been able to find a way to check to see if the pdf document is encrypted before calling doc.Read() so I can better handle this occurrence. Anyone know of a way?

Answer 1

check the doc encrption type to be 2?

bool encrypted = false;
using (Doc theDoc = new Doc())
{
    XReadOptions options = new XReadOptions { ReadModule = MyPDF.Pdf };
    theDoc.Read(inputbytearray, options);
    if (theDoc.Encryption.Type == 2)
      encrypted = true;
}
