This C# program is used to perform text operations in a file. Hence the AppendText() function is used to create a StreamWriter. It is used to append UTF-8 encoded text to an existing file or to a new file if the specified file does not exist.

Then CreateText() function is used to create or open a file for writing UTF-8 encoded text. The OpenText() function is used to open an existing UTF-8 encoded text file for reading. Here appending text, creating new text operations are performed and print the file text operations.
