TXT To HTML Translator - C# Programming Exercise

This C# exercise involves creating a "Text to HTML converter". The program should read a source text file and create an HTML file from its contents. The destination file should have the same name as the original file but with a ".html" extension instead of ".txt". Additionally, the title within the tag of the HTML file should be taken from the name of the source text file. This exercise is a great way to learn how to work with text and HTML files in C#, and it will help you understand how to generate HTML files dynamically from text files.

The program should read the content of the text file line by line and then generate an HTML file that contains each line of the text inside a

tag. The name of the text file should be used to create a title inside the tag. This exercise will teach you how to manipulate text strings and how to work with files in C#, as well as how to generate an HTML file with the proper structure.

At the end of this exercise, you will have a program capable of converting any text file into a well-structured HTML file, which can be useful in situations where you need to generate HTML content from plain text sources. This exercise is a practical way to practice file manipulation in C# and creating dynamic web content.

Exercise

TXT To HTML Translator

Objective

Create a "Text to HTML converter", which will read a source text file and create a 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.
