Given text, and we have to write it into a file using C# program.

File.WriteAllText()

This is a static method of "File" class, which is used to write all text (passed as an argument) in a file. Note: If the file does not exist at specified location, this method creates file first and then write all text to the file.

Syntax:

void File.WriteAllText(path, content);

Parameters:

1. path - Filename with its location.
2. content - Text to be written into file.

Program:

using System;

//We need to include this namespace for file handling.
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main()
        {
            string s;

            Console.WriteLine("Enter text to Write into File : ");
            s = Console.ReadLine();

            File.WriteAllText("ABC.TXT",s);
            Console.WriteLine("\nFile Creation Done");
        }
    }
}
