Summary
In this module, you learned about text file input and output in a C# application using the System.IO namespace. You explored how to create, read, write, and delete files using the File, Directory, and Path classes. You learned how to store and retrieve structured data using comma-separated values (CSV) files and the StreamReader and StreamWriter classes. You also learned about the FileStream class, and how read and write binary files using the BinaryReader and BinaryWriter classes.
The main takeaways from this module include using the Path, Directory, and File classes to work with files and directories, as well as the StreamReader and StreamWriter classes for reading from and writing to text files. You learned how to control file access in a more granular way using the FileStream class, and how to read and write binary files using the BinaryReader and BinaryWriter classes.
