C# program to demonstrate the use of CanWrite property

Syntax:

bool CanWrite

Program:

using System;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main()
        {
            byte[] b2 = new byte[6];

            FileStream f1;
            FileStream f2;

            f1 = new FileStream("abc.txt", FileMode.Open, FileAccess.Read);
            f2 = new FileStream("xyz.txt", FileMode.Open, FileAccess.Write);

            if (f1.CanWrite)
                Console.WriteLine("Yes, It can write.");
            else
                Console.WriteLine("Yes, It can not write.");


            f1.Close();

            if (f2.CanWrite)
                Console.WriteLine("Yes, It can write.");
            else
                Console.WriteLine("Yes, It can not write.");

            f2.Close();
        }
    }
}

Output:

Yes, It can not write.
