Steps to create AcroForms via .NET SDK

Aspose.PDF Cloud developers can easily load & create acroforms in PDF in just a few lines of code.

  1. Create an instance of PdfApi using your AppSid and AppSecret from Aspose Cloud Dashboard.
  2. Check Cloud Storage for File. Retrieve the list of files in cloud storage using GetFilesList(""). If the target file is not found, proceed to upload it.
  3. Upload PDF to Cloud Storage (if needed).
  4. Create a TextBox Field. Instantiate a TextBoxField object for page 1 and set properties.
  5. Add the Field to the PDF. Use PutTextBoxField to insert the field into the document stored in the cloud.
  6. Print Operation Status. Output the result status to the console.
 

This sample code shows creating an AcroForms in PDF documents


    public static void AddFormField()
    {
        const string localImageFileName = @"C:\Samples\StudentInfoFormElectronic.pdf";
        const string storageFileName = "StudentInfoFormElectronic.pdf";
        // Get your AppSid and AppSecret from https://dashboard.aspose.cloud (free registration required).            
        var pdfApi = new PdfApi(AppSecret, AppSid);
        var filesOnStorage = pdfApi.GetFilesList("");
        if (filesOnStorage.Value.All(f => f.Name != storageFileName))
        {
            using var file = File.OpenRead(localImageFileName);
            var uploadResult = pdfApi.UploadFile(storageFileName, file);
            Console.WriteLine(uploadResult.Uploaded[0]);
        }
        var textBoxField = new TextBoxField(PageIndex: 1)
        {
            PartialName = "Email",
            Rect = new Rectangle(100, 100, 180, 120),
            Value = "aspose-pdf-cloud@example.com",
            Border = new Border(Width: 5, Dash: new Dash(1, 1))
        };

        var response = pdfApi.PutTextBoxField(storageFileName, "Email", textBoxField);
        Console.WriteLine(response.Status);
    }
