Answer 1

The equivalent in C# would probably be a StreamReader or StreamWriter dependent upon whether you are reading or writing to a file.

A StreamReader :

Implements a TextReader that reads characters from a byte stream in a particular encoding.

Conversely, a StreamWriter :

Implements a TextWriter for writing characters to a stream in a particular encoding.

Some examples of using them (taken from the MS Documentation) are:

using (StreamReader sr = new StreamReader("TestFile.txt")) 
{
    string line;

    while ((line = sr.ReadLine()) != null)
    {
        Console.WriteLine(line);
    }
}

For the writer:

DirectoryInfo[] cDirs = new DirectoryInfo(@"c:\").GetDirectories();

using (StreamWriter sw = new StreamWriter("CDriveDirs.txt"))
{
    foreach (DirectoryInfo dir in cDirs)
    {
        sw.WriteLine(dir.Name);
    }
}

Information can be found about StreamReader from the docs . The equivalent form StreamWriter are in the docs .
