File I/O
Prerequisites: Records
File.WriteAllText("notes.txt", "Hello, file!");
string content = File.ReadAllText("notes.txt");
Console.WriteLine(content);
foreach (string line in File.ReadLines("notes.txt")) {
Console.WriteLine(line);
}
System.IO.File's static helper methods cover most simple cases
directly — reach for StreamReader/StreamWriter (seen in
Exception Handling's using example) for finer-grained control
over large files.
