Quick Start: Invoking a service using base64 in a Microsoft .NET project

The following C# code example invokes a process named EncryptDocument from a Microsoft .NET project using Base64 encoding. (See Invoking LiveCycle ES using Base64 Encoding.)

An unsecured PDF document based on a PDF file named map.pdf is passed to the LiveCycle ES process. The process returns a password-encrypted PDF document that is saved as a PDF file named mapEncrypt.pdf.

/*

 * Ensure that you create a .NET client assembly that uses 

 * base64 encoding. This is required to populate a BLOB 

 * object with data or retrieve data from a BLOB object.

 * 

 * For information, see "Invoking LiveCycle ES using Base64 Encoding" in 

 * Programming with LiveCycle ES
