// Get your AppSid and AppSecret https://dashboard.aspose.cloud (free registration required).
var pdfApi = new PdfApi(AppSecret, AppSid);
var filesOnStorage = pdfApi.GetFilesList("");
if (filesOnStorage.Value.All(f => f.Name != "sample.pdf"))
{
using var file = File.OpenRead(localImageFileName);
var uploadResult = pdfApi.UploadFile(storageFileName, file);
Console.WriteLine(uploadResult.Uploaded[0]);

var response = pdfApi.PutSetProperty(storageFileName, "xmp:ArchiveDate",
DateTime.Today.ToString(CultureInfo.InvariantCulture));
