'PdfTextExtractor' does not contain definition for 'GetTextFromPage'

‘PdfTextExtractor’ does not contain definition for ‘GetTextFromPage’, it throws Compiler Error CS0117

This is my code, which I have coppied just to check how does iText7 work:

using System;
using iText.Kernel.Pdf;
using iText.Kernel.Pdf.Canvas.Parser.Listener;

namespace PdfParser
{
    public static class PdfTextExtractor
    {
        public static void ExtractTextFromPDF(string filePath)
        {
            PdfReader pdfReader = new PdfReader(filePath);
            PdfDocument pdfDoc = new PdfDocument(pdfReader);

            for (int page = 1; page <= pdfDoc.GetNumberOfPages(); page++)
            {
                ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy();

                // the line below throws the exception
                string pageContent = PdfTextExtractor.GetTextFromPage(pdfDoc.GetPage(page), strategy);
            }

            pdfDoc.Close();
            pdfReader.Close();
        }
    }
}

I tried using iTextCsharp, but there was writen that iText7 is a new version.

I am working on "Console Application", maybe this is the problem? Should I use another framework?

>Solution :

The problem is that your class is also called PdfTextExtractor. Please rename your static class and the issue will be solved.

For future issues, you can jump to the reference (via F12 or similar, depending on your IDE/Shorctus) and check where it directs you.
