Gets the list of all fields in the DSN attachment.

Property Value

The key-value string collection of all the fields in the DSN attachment.

Remarks

This collection is alternative to other properties of DsnAttachment class. Other properties (like ArrivalDate) return the corresponding value in parsed form. Items property provides access to all the fields as they are specified in the DSN source. It can also be used to extract those values which are not available through other properties (for instance, vendor-specific properties which are not defined by RFC 1894).

Example

This code sample shows how to operate with parsed DSN data.
