How to enumerate PDF Form Field Values in C# .NET Framework

The first step when dealing with PDF form fields is a quick enumeration operation. Problem is, this is generally not so quick to get set up and working. Parsing PDF is not a fun task, requiring a great deal of special case logic and all that lovely stuff. So to help you out of this sticky situation, I will be showing you a simple method for using an API to enumerate PDF form fields in C#.

First, let’s go on NuGet and grab our package files:

Install-Package Cloudmersive.APIClient.NET.DocumentAndDataConvert -Version 3.2.8

Hot on the heals of that, we have our function call:

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Api;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Client;
using Cloudmersive.APIClient.NET.DocumentAndDataConvert.Model;
namespace Example
{
public class EditPdfGetFormFieldsExample
{
public void main()
{
// Configure API key authorization: Apikey
Configuration.Default.AddApiKey("Apikey", "YOUR_API_KEY");
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// Configuration.Default.AddApiKeyPrefix("Apikey", "Bearer");
var apiInstance = new EditPdfApi();
var inputFile = new System.IO.Stream(); // System.IO.Stream | Input file to perform the operation on.
try
{
// Gets PDF Form fields and values
PdfFormFields result = apiInstance.EditPdfGetFormFields(inputFile);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling EditPdfApi.EditPdfGetFormFields: " + e.Message );
}
}
}
}

And done!
