Read the contents of a file into a string
ruby
file = File.new("Solution108.rb")
whole_file = file.read
whole_file = file.read
csharp
string contents = System.IO.File.ReadAllText("filename.txt");
Process a file one line at a time
Open the source file to your solution and print each line in the file, prefixed by the line number, like:
1> First line of file
2> Second line of file
3> Third line of file
1> First line of file
2> Second line of file
3> Third line of file
ruby
File.open("Solution103.rb").each_with_index { |line, count|
puts "#{count} > #{line}
}
puts "#{count} > #{line}
}
csharp
int counter = 0;
// If the file is large, you would want to buffer this instead of reading everything at once
foreach (string line in System.IO.File.ReadAllLines("filename.txt"))
{
Console.WriteLine("{0}> {1}", ++counter, line);
}
// If the file is large, you would want to buffer this instead of reading everything at once
foreach (string line in System.IO.File.ReadAllLines("filename.txt"))
{
Console.WriteLine("{0}> {1}", ++counter, line);
}
