GroupDocs.Metadata for .NET offers advanced file metadata processing in .NET with easy-to-use methods. It supports custom metadata handling in .NET applications and reading and manipulating the built-in metadata among supported data files. The metadata library for .NET is the perfect choice for developing Word and PDF metadata editors that can add and update custom metadata properties while managing the default or built-in metadata smoothly. This section explains the API’s ability to read metadata in Word documents and extract PDF metadata easily.
With the help of the document metadata manipulation API, developers can build comprehensive solutions to access, view, and manipulate the metadata in Word documents. The following C# coding example provides more information on reading and displaying built-in DOCX metadata properties.
using (Metadata metadata = new Metadata("C:\MetadataTest\source.docx"))
{
var root = metadata.GetRootPackage();
Console.WriteLine(root.DocumentProperties.Author);
Console.WriteLine(root.DocumentProperties.CreatedTime);
Console.WriteLine(root.DocumentProperties.Company);
Console.WriteLine(root.DocumentProperties.Category);
Console.WriteLine(root.DocumentProperties.Keywords);
// ...
}
The metadata of PDF documents provides insight into different file attributes, similar to other file formats. You can programmatically extract metadata from PDFs using the .NET API and process it as needed. The code sample below focuses on extracting and displaying the PDF metadata property values.
using (Metadata metadata = new Metadata(“C:\MetadataTest\sourceFile.pdf”))
{
// Fetch all metadata properties from the file
var properties = metadata.FindProperties(p => true);
foreach (var property in properties)
{
// Process string and DateTime properties only
if (property.Value.Type == MetadataPropertyType.String)
{
Console.WriteLine(property.Value.ToClass());
}
else if (property.Value.Type == MetadataPropertyType.DateTime)
{
Console.WriteLine(property.Value.ToStruct(DateTime.MinValue));
}
}
}
