Understanding HTML:

Before diving into the conversion process, let's briefly discuss what HTML is. HTML, or HyperText Markup Language, is the standard markup language used to create web pages. It consists of various elements enclosed in tags, which define the structure and presentation of content on a webpage.

Why Convert HTML to Plain Text?

While HTML is great for displaying content on web pages, sometimes we need to work with the text alone, without any formatting or styling. This is where converting HTML to plain text comes in handy. Plain text contains only the raw textual content, making it easier to analyze, process, or manipulate programmatically.

Converting HTML to Plain Text in C#:

Now, let's get into the practical aspect of converting HTML to plain text using C#. Below is a simple C# program that demonstrates this conversion:

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main(string[] args)
    {
        string htmlContent = "<h1>Hello, <em>world</em>!</h1>";
        string plainText = StripHtmlTags(htmlContent);
        Console.WriteLine(plainText);
    }

    static string StripHtmlTags(string html)
    {
        return Regex.Replace(html, "<.*?>", string.Empty);
    }
}

In this program, we define a method called StripHtmlTags, which takes an HTML string as input and uses a regular expression to remove all HTML tags from it. The Main method demonstrates how to use this function by providing a sample HTML content and printing the resulting plain text.

Output:

When you run the above program, the output will be:

Hello, world!
