Dapatkan Metadata XMP dari File PDF

Untuk mendapatkan metadata XMP dari file PDF, Anda perlu membuat objek PdfXmpMetadata dan mengikat file PDF menggunakan metode BindPdf. Anda dapat mengirimkan properti metadata XMP tertentu ke objek PdfXmpMetadata untuk mendapatkan nilainya. Potongan kode berikut menunjukkan cara mendapatkan metadata XMP dari file PDF.

.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();
}
