Program Explanation

This C# program is used to generate random file names to store certain kinds of data. Using Path.GetRandomFileName, write name to files that have cryptographically-secure random names. This can enhance security or simplicity in the program.


The Path.GetRandomFileName method returns a random file name with an extension. This includes the period before the extension. The extension will be 1 dot and 3 letters, while the name will be 8 characters. The WriteRandomFile is called three times.

The WriteRandomFile method internally gets a random file name, gets the correct output path, and then writes some text to it. Using the random function print the strings randomly generated.
