Count the Replace Patterns Set on an Email

See more Email Object Examples

Demonstrates the read-only Chilkat Email.NumReplacePatterns property, which returns how many replacement patterns have been set via SetReplacePattern. When replacement patterns are present, the email bodies and header fields are modified by applying the search/replacement strings during the sending process. Pattern indexes are zero-based. This example sets two patterns and prints the count.
