C#: Create a file with content in the disk

C# Sharp File Handling: Exercise-4 with Solution

Write a program in C# Sharp to create a file and add some text.

Sample Solution:-

C# Sharp Code:

using System; // Importing the System namespace
using System.IO; // Importing the System.IO namespace for file operations
using System.Text; // Importing the System.Text namespace for encoding

class filexercise2 // Declaring a class named filexercise2
{
    public static void Main() // Declaring the Main method
    {
        string fileName = @"mytest.txt"; // Initializing a string variable with the file name

        try // Starting a try block to catch exceptions
        {
            // Delete the file if it exists.
            if (File.Exists(fileName)) // Checking if the file exists
            {
                File.Delete(fileName); // If the file exists, delete it
            }
			
            // Displaying a message to create a file with content in the disk
            Console.Write("\n\n Create a file with content in the disk :\n");
            Console.Write("---------------------------------------------\n");

            // Create the file and write content to it.
            using (StreamWriter fileStr = File.CreateText(fileName)) // Creating a StreamWriter to write text to the file
            {
                // Writing content to the file
                fileStr.WriteLine(" Hello and Welcome");
                fileStr.WriteLine(" It is the first content");
                fileStr.WriteLine(" of the text file mytest.txt");
                Console.WriteLine(" A file created with content name mytest.txt\n\n"); // Displaying a message indicating successful file creation with content
            }				
        }
        catch (Exception MyExcep) // Catching any exceptions that might occur
        {
            Console.WriteLine(MyExcep.ToString()); // Displaying the exception details if any
        }
    }
}

Sample Output:

 Create a file with content in the disk :                                                                     
---------------------------------------------                                                                 
 A file created with content name mytest.txt
