Here is a basic C# example:

var Ocr = new IronTesseract(); // nothing to configure            
Ocr.Language = OcrLanguage.EnglishBest;                                     
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5;            
using (var Input = new OcrInput())      
{          
    Input.AddImage(@"Demo.png");         
    var Result = Ocr.Read(Input);       
    Console.WriteLine(Result.Text);        
    Console.ReadKey();          
}

var Ocr = new IronTesseract(); // nothing to configure            
Ocr.Language = OcrLanguage.EnglishBest;                                     
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5;            
using (var Input = new OcrInput())      
{          
    Input.AddImage(@"Demo.png");         
    var Result = Ocr.Read(Input);       
    Console.WriteLine(Result.Text);        
    Console.ReadKey();          
}

Dim Ocr = New IronTesseract() ' nothing to configure
Ocr.Language = OcrLanguage.EnglishBest
Ocr.Configuration.TesseractVersion = TesseractVersion.Tesseract5
Using Input = New OcrInput()
	Input.AddImage("Demo.png")
	Dim Result = Ocr.Read(Input)
	Console.WriteLine(Result.Text)
	Console.ReadKey()
End Using

VB C#

The above code allows us to extract data from the image with the best OCR accuracy. IronOCR also helps us to convert extracted text from handwritten documents into editable formats such as Word file formats. We are also able to convert the scanned document into a searchable PDF.
