to get the latest version.
Please check the GitHub Repository for other common usage scenarios.
Use C# to Remove All Metadata Properties from a File
using (Metadata metadata = new Metadata(Constants.InputPdf))
{
// Remove detected metadata packages
var affected = metadata.Sanitize();
Console.WriteLine("Properties removed: {0}", affected);
metadata.Save(Constants.OutputPdf);
}
Extract Metadata from Files via C# Code
foreach(string file in Directory.GetFiles(Constants.InputPath)) {
using(Metadata metadata = new Metadata(file)) {
if (metadata.FileFormat != FileFormat.Unknown && !metadata.GetDocumentInfo().IsEncrypted) {
Console.WriteLine();
Console.WriteLine(file);
// fetch all metadata properties that fall into a particular category
var properties = metadata.FindProperties(p => p.Tags.Any(t => t.Category == Tags.Content));
Console.WriteLine("The metadata properties describing some characteristics of the file content: title, keywords, language, etc.");
foreach(var property in properties) {
Console.WriteLine("{0} = {1}", property.Name, property.Value);
}
// fetch all properties having a specific type and value
var year = DateTime.Today.Year;
properties = metadata.FindProperties(p => p.Value.Type == MetadataPropertyType.DateTime &&
p.Value.ToStruct(DateTime.MinValue).Year == year);
Console.WriteLine("All datetime properties with the year value equal to the current year");
foreach(var property in properties) {
Console.WriteLine("{0} = {1}", property.Name, property.Value);
}
}
}
}
