Get a Header Field by Name
See more Email Object Examples
Demonstrates the Chilkat Email.GetHeaderField method, which returns the value of a header field by name. Header-field names are case-insensitive, so X-Priority and x-priority refer to the same field. This example reads several headers by name.
Background: Looking up a header by name is the quickest way to read a known field like
Subject or a custom X- header. One caveat: some header names (such as Received) can legitimately appear more than once. When a field may repeat and you need every occurrence, enumerate by index with GetHeaderFieldName and GetHeaderFieldValue instead of looking up by name.Chilkat Tcl Downloads
