After writing everything you want to a file through a StreamWriter,
what do you still need to remember to do?
If you want to create a file path in an operating system independent way for file f.txt in directory d2, which is a subdirectory of d1, which is a subdirectory of the current directory, how would you do it?
Windows uses \ as a path separator. If you want to write a literal
directly for a Windows path, what issue is there in C#?
In a file path, how do you refer to the parent directory of the current directory, without using the actual name of the parent directory?
If you are reading from a StreamReader inFile, what is logically
wrong with the following:
if (inFile.ReadLine().Contains("!")) {
Console.WriteLine(inFile.ReadLine() + "\n contains the symbol !"
}
