  • 0

I’m using itextsharp to extract the modified date from a pdf file. The string gets returned in this format: D:20120224093340. I’m trying to parse that string into a date time like so:

string modDate = "";

reader.Info.TryGetValue("ModDate", out modDate);

System.Globalization.CultureInfo provider = 
System.Globalization.CultureInfo.InvariantCulture;

pdfModDate = DateTime.ParseExact(formattedDate, "D:yyyyddMMHHmmss", provider);

But I get this error message: The DateTime represented by the string is not supported in calendar System.Globalization.GregorianCalendar.

I have no idea what this error means. This code should be working…

    Your month is 24, which is not supported by the Gregorian calendar 🙂
