Step 1: Create a Dropbox API
To create a Dropbox API App, you should follow the official documentation provided by Dropbox link. The process involves visiting the Dropbox Developer website and using their App Console to set up your API app. This app will allow you to interact with Dropbox programmatically, enabling secure access to files and data.
Step 2: Create a simple console application
Step 3: Install the Syncfusion.Pdf.Net.Core and Dropbox.Api NuGet packages as a reference to your project from the NuGet.org.
Step 4: Include the following namespaces in the Program.cs file.
using Syncfusion.Pdf.Graphics;
using Syncfusion.Pdf;
using Dropbox.Api;
using Dropbox.Api.Files;
using Syncfusion.Drawing;
Step 5: Add the below code example to create a simple PDF and save in Dropbox cloud file storage.
// Create a new PDF document.
PdfDocument doc = new PdfDocument();
// Add a new page to the document.
PdfPage page = doc.Pages.Add();
// Get the graphics object for the page to draw on.
PdfGraphics graphics = page.Graphics;
// Create a font for drawing text.
PdfFont font = new PdfStandardFont(PdfFontFamily.Helvetica, 12);
// Draw the text
graphics.DrawString("Hello, World!", font, PdfBrushes.Black, new PointF(10, 10));
// Save the PDF to a memory stream.
MemoryStream stream = new MemoryStream();
doc.Save(stream);
// Close the PDF document.
doc.Close(true);
var accessToken = "YOUR_ACCESS_TOKEN";// Replace with your actual access token
// Initialize a DropboxClient with the provided access token.
using (var dbx = new DropboxClient(accessToken))
{
// Upload the PDF to Dropbox.
var uploadResult = await dbx.Files.UploadAsync(
"/path/to/save/Sample.pdf",
WriteMode.Overwrite.Instance,
body: new MemoryStream(stream.ToArray()));
}
