How do you upload file in console application?

In a console application, you typically upload a file by prompting the user to provide the file path and then using file handling functions to read the file. For example, in C#, you can use File.ReadAllText() or File.ReadAllLines() to read the contents of the file after validating the path. In Python, you can use the built-in open() function to access the file. Ensure proper error handling to manage cases where the file may not exist or the path is invalid.
