To read the content of a PDF file as text in C# Winforms, you can use a library called iTextSharp. Follow the steps below to achieve this:

Install the iTextSharp library: You can install the iTextSharp library using NuGet. Right-click on your project in Visual Studio, select "Manage NuGet Packages," search for "iTextSharp," and install the library.

Import the necessary namespaces: Add the following using directives at the top of your C# file:

using iTextSharp.text;
using iTextSharp.text.pdf;
Create a method to read the PDF file:

private string ReadPdfFile(string filePath)
{
StringBuilder text = new StringBuilder();

using (PdfReader reader = new PdfReader(filePath))
{
for (int i = 1; i <= reader.NumberOfPages; i++)
{
text.Append(PdfTextExtractor.GetTextFromPage(reader, i));
}
}

return text.ToString();
}
Call the ReadPdfFile method with the path of your PDF file:

string filePath = "path_to_your_pdf_file.pdf";
string pdfText = ReadPdfFile(filePath);
The pdfText variable will contain the extracted text from the PDF file.

Make sure to replace "path_to_your_pdf_file.pdf" with the actual path to your PDF file.

Remember to handle exceptions that may occur when working with the PDF file, such as PdfReaderException or IOException.
