[NAL]

Hello,

I downloaded the free .NET Spire.pdf and I'm trying to searh a text and highlight it.
But I have an error on the ExtractText method..

"An unhandled exception of type 'System.FormatException' occurred in mscorlib.dll"
"Additional information: Le format de la chaîne d'entrée est incorrect."

and here is the code I'm running in console application

if (item == @"D:\TEMP\TEST_PDF\page_0105.pdf")
{
PdfDocument pdf = new PdfDocument();
pdf.LoadFromFile(item);


StringBuilder content = new StringBuilder();
content.Append(pdf.Pages[0].ExtractText());
String fileName = @"D:\TEMP\TextFromPDF.txt";
File.WriteAllText(fileName, content.ToString());
System.Diagnostics.Process.Start("TextFromPDF.txt");
pdf.Close();
}


I tried the code finded in your tutorials code too but the same error appears..

Can you help me please ?

If someone has already have the same error, I think it is not about the code but about some configuration..

Hi, I'm facing the same problem.

I'm using "spire.pdf-fe_3.2" in a clean installation of Visual Studio 2013 Ultimate, Windows 8.1 x64.

I even ran the sample included in the installer, and the problem is still there.

Regards.
