Add and Delete PDF Document Properties using Spire.Cloud.PDF

This article demonstrates how to add and delete PDF document properties using the PdfPropertiesApi interface provided by Spire.Cloud.PDF.

Add document properties

using Spire.Cloud.Pdf.Sdk.Api;
using Spire.Cloud.Pdf.Sdk.Client;
using Spire.Cloud.Pdf.Sdk.Model;
using System;
using System.Collections.Generic;

namespace AddPDFProperties
{
    class Program
    {
        static String appId = "APP ID";
        static String appKey = "APP Key";
        static String baseUrl = "https://api.cloudxdocs.com";
        //Create a Configuration instance based on your AppID and AppKey
        static Configuration PdfConfiguration = new Configuration(appId, appKey, baseUrl);
        //Create a PdfPropertiesApi instance
        static PdfPropertiesApi pdfPropertiesApi = new PdfPropertiesApi(PdfConfiguration);
        static void Main(string[] args)
        {
            //Specify the input document
            string name = "Sample.pdf";
            //Specify the folder storing the input document, and it's "null" if nothing
            string folder = "input";
            //Specify the password used to open the document, and it's "null" if nothing
            string password = null;
            //Use the 2G storage provided by E-iceblue, and it's "null" by default
            string storage = null;
            //Specify the file path of the output document
            string outPath = "output/AddOrUpdateProperties_output.pdf";

            //Create a DocumentProperties instance
            DocumentProperties properties = new DocumentProperties();

            //Create a list of document properties
            properties.List = new List();
            //buildin properties
            properties.List.Add(new DocumentProperty("author", "Simon"));
            properties.List.Add(new DocumentProperty("creator", "Simon2"));
            properties.List.Add(new DocumentProperty("keywords", "the keywords"));
            properties.List.Add(new DocumentProperty("producer", "Spire.pdf"));
            properties.List.Add(new DocumentProperty("subject", "the subject"));
            properties.List.Add(new DocumentProperty("title", "the title"));
            //customized properties
            properties.List.Add(new DocumentProperty("customizedProperty1", "the customizedProperty1"));
            properties.List.Add(new DocumentProperty("customizedProperty2", "the customizedProperty2"));
            properties.List.Add(new DocumentProperty("Name", " Lisa"));

            //Call the AddOrUpdateProperties method to add properties to the document and save to a specified path
            pdfPropertiesApi.AddOrUpdateProperties(name, outPath, properties, folder, storage, password);
        }
    }
}
