IronPDF — The C# PDF Reading Library
IronPDF is a perfect go-to tool for all PDF-related tasks for software engineers using the C# or VB .NET languages. IronPDF offers developers support to render PDF documents into images, extract text and content from a PDF, make searchable PDF files, search specific items, or act as an annotation inspector for your PDF files.
IronPDF does not actually function as a traditional pdf viewer, but allows you to read and therefore view pdf content or annotations as data for review in your .net application out of the box.
If you prefer to view PDF file documents in C# .NET applications, then the PdfDocument.ExtractAllText method in the IronPDF library is also easy to use. The following code can be used to view a PDF using IronPDF in C#.
public Form1()
{
InitializeComponent();
//Select the Desired PDF File
PdfDocument PDF = PdfDocument.FromFile("any.pdf");
//Extract every single text from an pdf
string AllText = PDF.ExtractAllText();
//View text in an Label or textbox
label2.Text = AllText;
//Get all Images
IEnumerable<Image> AllImages = PDF.ExtractAllImages();
//View Image in a PictureBox
pictureBox1.Image = AllImages.First();
//Else Combine above both functionality using PageCount
for (var index = 0; index < PDF.PageCount; index++)
{
int PageNumber = index + 1;
string Text = PDF.ExtractTextFromPage(index);
IEnumerable<Image> Images = PDF.ExtractImagesFromPage(index);
}
}
public Form1()
{
InitializeComponent();
//Select the Desired PDF File
PdfDocument PDF = PdfDocument.FromFile("any.pdf");
//Extract every single text from an pdf
string AllText = PDF.ExtractAllText();
//View text in an Label or textbox
label2.Text = AllText;
//Get all Images
IEnumerable<Image> AllImages = PDF.ExtractAllImages();
//View Image in a PictureBox
pictureBox1.Image = AllImages.First();
//Else Combine above both functionality using PageCount
for (var index = 0; index < PDF.PageCount; index++)
{
int PageNumber = index + 1;
string Text = PDF.ExtractTextFromPage(index);
IEnumerable<Image> Images = PDF.ExtractImagesFromPage(index);
}
}
