C # operate Word documents (encryption, decryption, and insert pagination characters to corresponding bookmarks)

Recently, in a project, the customer requested to display the content in the generated RTF file by page. As he had no idea about this, he also found relevant information on the Internet, in addition, I used my own search on msdn to solve the problem. The following is a simple summary of C # Word documents (encryption, decryption, and pagination). I hope to help some friends. Pai_^

Before writing code, you need to reference the corresponding DLL file:
