EmlRootPackage

EmlRootPackage class

Represents the root package allowing working with metadata in an EML email message.

public class EmlRootPackage : EmailRootPackage

Properties

Name Description
Count { get; } Gets the number of metadata properties.
EmailPackage { get; } Gets the EML metadata package. (2 properties)
FileType { get; } Gets the file type metadata package.
Item { get; } Gets the MetadataProperty with the specified name.
Keys { get; } Gets a collection of the metadata property names.
MetadataType { get; } Gets the metadata type.
PropertyDescriptors { get; } Gets a collection of descriptors that contain information about properties accessible through the GroupDocs.Metadata search engine.

Methods

Name Description
virtual AddProperties(Func<MetadataProperty, bool>, PropertyValue) Adds known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.
ClearAttachments() Removes all the attachments form the email message.
Contains(string) Determines whether the package contains a metadata property with the specified name.
virtual FindProperties(Func<MetadataProperty, bool>) Finds the metadata properties satisfying the specified predicate. The search is recursive so it affects all nested packages as well.
GetEnumerator() Returns an enumerator that iterates through the collection.
virtual RemoveProperties(Func<MetadataProperty, bool>) Removes metadata properties satisfying the specified predicate.
override Sanitize() Removes writable metadata properties from the package. The operation is recursive so it affects all nested packages as well.
virtual SetProperties(Func<MetadataProperty, bool>, PropertyValue) Sets known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well. This method is a combination of AddProperties and UpdateProperties. If an existing property satisfies the predicate its value is updated. If there is a known property missing in the package that satisfies the predicate it is added to the package.
virtual UpdateProperties(Func<MetadataProperty, bool>, PropertyValue) Updates known metadata properties satisfying the specified predicate. The operation is recursive so it affects all nested packages as well.

Examples

This code sample shows how to extract metadata from an EML message.

using (Metadata metadata = new Metadata(Constants.InputEml))
{
    var root = metadata.GetRootPackage<EmlRootPackage>();

    Console.WriteLine(root.EmailPackage.Sender);
    Console.WriteLine(root.EmailPackage.Subject);
    foreach (string recipient in root.EmailPackage.Recipients)
    {
        Console.WriteLine(recipient);
    }

    foreach (var attachedFileName in root.EmailPackage.AttachedFileNames)
    {
        Console.WriteLine(attachedFileName);
    }

    foreach (var header in root.EmailPackage.Headers)
    {
        Console.WriteLine("{0} = {1}", header.Name, header.Value);
    }

    // ...
}
