File Text to HTML Converter in C#

This program is a "Text to HTML Converter" that reads the contents of a source text file and converts it into an HTML file. The program will take the text file and process its contents to generate an HTML file with the same name but with the ".html" extension. The HTML file will include a "head" section with a title based on the name of the source file (without the ".txt" extension). The body of the HTML document will contain the contents of the text file, with each line wrapped in a <p> (paragraph) tag. This program is useful for converting plain text documents into a basic HTML format.

File Handling in C#

Objective

1. The program will prompt the user for the name of the text file to be converted.
2. The program will read the contents of the text file.
3. It will generate an HTML file with the same name as the text file but with a ".html" extension.
4. The content of the text file will be placed within the of the HTML file, with each line wrapped in a

tag.
5. The "title" of the HTML file will be set to the name of the text file (without the ".txt" extension).
6. If the file is not found or there is an error, appropriate messages will be shown.

Create a "Text to HTML converter", which will read a source text file and create an HTML file from its contents. For example, if the file contains:

Hola
Soy yo
Ya he terminado

The name of the destination file must be the same as the source file, but with ".html" extension (which will replace the original ".txt" extension, if it exists). The "title" in the "head" must be taken from the file name.

Example C# Exercise

 Copy C# Code 
using System;
using System.IO;

class TextToHtmlConverter
{
    // Main method to run the program
    static void Main(string[] args)
    {
        // Ask the user to enter the name of the text file
        Console.WriteLine("Please enter the name of the text file:");

        // Read the name of the text file from the user input
        string fileName = Console.ReadLine();

        try
        {
            // Check if the file has a ".txt" extension
            if (!fileName.EndsWith(".txt"))
            {
                Console.WriteLine("Error: The file must have a .txt extension.");
                return;
            }

            // Open the text file for reading
            string[] lines = File.ReadAllLines(fileName);

            // Create the output HTML file with the same name, but with a ".html" extension
            string htmlFileName = Path.ChangeExtension(fileName, ".html");

            // Open the HTML file for writing
            using (StreamWriter writer = new StreamWriter(htmlFileName))
            {
                // Write the opening HTML tags and the title based on the file name (without ".txt")
                writer.WriteLine("");
                writer.WriteLine("");
                writer.WriteLine($"{Path.GetFileNameWithoutExtension(fileName)}");
                writer.WriteLine("");
                writer.WriteLine("");

                // Write each line from the text file as a paragraph in the HTML file
                foreach (string line in lines)
                {
                    writer.WriteLine($"
{line}
");
                }

                // Close the body and HTML tags
                writer.WriteLine("");
                writer.WriteLine("");
            }

            // Inform the user that the HTML file has been created
            Console.WriteLine($"HTML file '{htmlFileName}' has been created successfully.");
        }
        catch (FileNotFoundException)
        {
            // Handle file not found error
            Console.WriteLine("Error: The specified text file could not be found.");
        }
        catch (Exception ex)
        {
            // Handle other unexpected errors
            Console.WriteLine("An error occurred: " + ex.Message);
        }
    }
}

 Output

//If the user enters example.txt and the file contains the following lines:
Hola
Soy yo
Ya he terminado

//The program will create a file named example.html with the following content:
<html>
<head>
<title>example</title>
</head>
<body>
<p>Hola</p>
<p>Soy yo</p>
<p>Ya he terminado</p>
</body>
</html>
