Methods

Clone()

Creates a new instance of the Metadata class that is a copy of the current instance.

Returns: Metadata. A new Metadata object that is a copy of this instance.

This method creates a deep copy of the current metadata, allowing modifications to the clone without affecting the original.

  var original = new Metadata();
  var clone = original.Clone();

GetProperties()

Retrieves all property names within the metadata.

Returns: String[]. An array of strings containing all property names.

This method returns the keys of all stored metadata entries as an array of strings. If the metadata is empty, it returns an empty array.

  var metadata = new Metadata();
  var properties = metadata.GetProperties();

Remove(keys)

Removes metadata entries with the specified keys.

Parameter	Type	Description
keys	String[]	An array of keys identifying the metadata entries to remove.

This method will iterate through the provided keys and remove the corresponding entries from the metadata. If the metadata is empty or the keys do not exist, the method does nothing.

  var metadata = new Metadata();
  metadata["key1"] = "value1";
  metadata.Remove("key1");
