C# Program to Illustrate Methods of FileInfo Class

Code:

using System;
using System.IO;
class Test
{
    public static void Main()
    {
        string path = Path.GetTempFileName();
        FileInfo fi1 = new FileInfo(path);
        using (StreamWriter sw = fi1.CreateText())
        {
            sw.WriteLine("This is");
            sw.WriteLine("Sanfoundry");
            sw.WriteLine("Website");
        }
        using (StreamReader sr = fi1.OpenText())
        {
            string s = "";
            while ((s = sr.ReadLine()) != null)
            {
                Console.WriteLine(s);
            }
        }
        try
        {
            string path2 = Path.GetTempFileName();
            FileInfo fi2 = new FileInfo(path2);
            fi2.Delete();
            fi1.CopyTo(path2);
            Console.WriteLine("{0} was copied to {1}.", path, path2);
            fi2.Delete();
            Console.WriteLine("{0} was successfully deleted.", path2);
        }
        catch (Exception e)
        {
            Console.WriteLine("The process failed: {0}", e.ToString());
        }
        Console.Read();
    }
}



Output:
