Examples
This example demonstrates how to traverse the whole metadata tree for a specific file regardless of the format.
public static void Run()
{
using (Metadata metadata = new Metadata(Constants.JpegWithXmp))
{
DisplayMetadataTree(metadata.GetRootPackage(), 0);
}
}
private static void DisplayMetadataTree(MetadataPackage package, int indent)
{
if (package != null)
{
var stringMetadataType = package.MetadataType.ToString();
Console.WriteLine(stringMetadataType.PadLeft(stringMetadataType.Length + indent));
foreach (MetadataProperty property in package)
{
string stringPropertyRepresentation = string.Format("Name: {0}, Value: {1}", property.Name, property.Value);
Console.WriteLine(stringPropertyRepresentation.PadLeft(stringPropertyRepresentation.Length + indent + 1));
if (property.Value != null)
{
switch (property.Value.Type)
{
case MetadataPropertyType.Metadata:
DisplayMetadataTree(property.Value.ToClass<MetadataPackage>(), indent + 2);
break;
case MetadataPropertyType.MetadataArray:
DisplayMetadataTree(property.Value.ToArray<MetadataPackage>(), indent + 2);
break;
}
}
}
}
}
private static void DisplayMetadataTree(MetadataPackage[] packages, int indent)
{
if (packages != null)
{
foreach (var package in packages)
{
DisplayMetadataTree(package, indent);
}
}
}
