        Rectangle r = new Rectangle();
        r.GetDetails();
        r.Display();
        r.WriteToFile(); //this is the main method in which i need the area of the rectangle to be wrote to the file
        Console.ReadLine();

    }
}

I can't see your code to write an object to a file. And please post [MCVE] — Khalil Khalaf, Jun 24 '16 at 13:04
Have you even researched how to write text to a file? A good Google will throw up thousands of results on how to do this... — Geoff James, Jun 24 '16 at 13:05
What about just `System.IO.File.WriteAllText`? Have you tried it? — Andy Korneyev, Jun 24 '16 at 13:05

You can use the File class:

File.WriteAllText("filename.txt", GetArea().ToString());

This will write the file in the same folder as your exe, otherwise use a full path like @"C:\filename.txt". If you faced any unauthorized exception, run Visual studio as administrator.

This will write it to the file location of your choice.

 public void writeToFile(){

 System.IO.File.WriteAllLines(@"C:\Users\Public\TestFolder\WriteLines.txt", getArea().toString());

 }
