Check if a MIME Part is Plain Text
See more MIME Examples
Demonstrates the Chilkat Mime.IsPlainText method, which returns whether the Content-Type is exactly text/plain. It takes no arguments and applies to the current part.
Note: The file path is relative to the application's current working directory. Absolute paths may also be used. Supply the path to your own file.
Background: Inside a
