Add the resulting assembly as reference in your projects, and this line on code:
using VAR.PdfTools;
```csharp
using VAR.PdfTools;
```
Then extract the contents of a data column using:
```csharp
var columnData = new List<string>();
PdfDocument doc = PdfDocument.Load("document.pdf");
foreach (PdfDocumentPage page in doc.Pages)
{
PdfTextExtractor extractor = new PdfTextExtractor(page);
columnData.AddRange(extractor.GetColumn("Column"));
columnData.AddRange(extractor.GetColumnAsStrings("Column"));
}
```
Or the content of a field (text on the right of the indicated text):
```csharp
var fieldData = new List<string>();
PdfDocument doc = PdfDocument.Load("document.pdf");
foreach (PdfDocumentPage page in doc.Pages)
{
PdfTextExtractor extractor = new PdfTextExtractor(page);
fieldData.Add(extractor.GetField(txtFieldName.Text));
fieldData.Add(extractor.GetFieldAsString(txtFieldName.Text));
}
```
