Namespace:   System.IO

public abstract bool CanRead { get; }

using System;
using System.IO;

class TestRW 
    public static void Main(String[] args)
        FileStream fs = new FileStream("MyFile.txt", FileMode.OpenOrCreate, FileAccess.Read);
        if (fs.CanRead && fs.CanWrite)
            Console.WriteLine("MyFile.txt can be both written to and read from.");
        else if (fs.CanRead)
            Console.WriteLine("MyFile.txt is not writable.");
