Get XMP Metadata of PDF File

In order to get XMP metadata from a PDF file, you need to create PdfXmpMetadata object and bind the PDF file using BindPdf method. You can pass specific XMP metadata properties to the PdfXmpMetadata object to get their values. The following code snippet shows you how to get XMP metadata from a PDF file.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void GetXmpMetadata()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdfFacades_WorkingDocuments();

    // Create PdfXmpMetadata object
    using (var xmpMetaData = new Aspose.Pdf.Facades.PdfXmpMetadata())
    {
        // Bind PDF document
        xmpMetaData.BindPdf(dataDir + "GetXMPMetadata.pdf");

        // Get XMP Meta Data properties
        Console.WriteLine(": {0}", xmpMetaData[Aspose.Pdf.Facades.DefaultMetadataProperties.CreateDate].ToString());
        Console.WriteLine(": {0}", xmpMetaData[Aspose.Pdf.Facades.DefaultMetadataProperties.MetadataDate].ToString());
        Console.WriteLine(": {0}", xmpMetaData[Aspose.Pdf.Facades.DefaultMetadataProperties.CreatorTool].ToString());
        Console.WriteLine(": {0}", xmpMetaData["customNamespace:UserPropertyName"].ToString());

        Console.ReadLine();
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET
private static void GetXmpMetadata()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdfFacades_WorkingDocuments();

    // Create PdfXmpMetadata object
    using var xmpMetaData = new Aspose.Pdf.Facades.PdfXmpMetadata();

    // Bind PDF document
    xmpMetaData.BindPdf(dataDir + "GetXMPMetadata.pdf");

    // Get XMP Meta Data properties
    Console.WriteLine(": {0}", xmpMetaData[Aspose.Pdf.Facades.DefaultMetadataProperties.CreateDate].ToString());
    Console.WriteLine(": {0}", xmpMetaData[Aspose.Pdf.Facades.DefaultMetadataProperties.MetadataDate].ToString());
    Console.WriteLine(": {0}", xmpMetaData[Aspose.Pdf.Facades.DefaultMetadataProperties.CreatorTool].ToString());
    Console.WriteLine(": {0}", xmpMetaData["customNamespace:UserPropertyName"].ToString());

    Console.ReadLine();
}
