Converting unicode not working in c#

Question

I am trying to convert unicode character in c# but it is not working

code:

using System;
using System;
using System.Net;
using System.IO;
using System.Text.RegularExpressions;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Threading;

namespace test_request
{
    class MainClass
    {
        public static void Main (string[] args)
        {

            string unicode = "Not Your Boyfriend&#39;s Tunic";
            string str = System.Uri.UnescapeDataString(unicode);


            Console.WriteLine (str);
        }
    }
}

Ouput:

Not Your Boyfriend&#39;s Tunic

But expected output is this

Expected output:

Not Your Boyfriend's Tunic

may be it works :`string unicode = EncodeNonAsciiCharacters(unicodeString);` — Amol Raje, Dec 07 '17 at 05:25

@AmolRaje What is `EncodeNonAsciiCharacters`? What namespace and class does it live in? Is it a method you have implmented in your own project, by any chance? — ProgrammingLlama, Dec 07 '17 at 05:33

Use below function:

HttpUtility.HtmlDecode("Not Your Boyfriend&#39;s Tunic");
HttpUtility.HtmlEncode("Not Your Boyfriend's Tunic");

Both solutions will work for you:

Using Server.HtmlDecode:

 string unicode = "Not Your Boyfriend&#39;s Tunic";
 string str = Server.HtmlDecode(unicode);
 Console.WriteLine (str);

reference link: This MSDN document.

Using HttpUtility.HtmlDecode: hello

string unicode = "Not Your Boyfriend&#39;s Tunic";    
string str = HttpUtility.HtmlDecode(unicode);
Console.WriteLine (str);

reference link: This MSDN document.

Difference between both:

Both does same work but the only difference is: Server.HtmlDecode() is readily availalble at runtime from a web page whereas HttpUtility.HtmlDecode() is a static method that can be used from anywhere.

using System.Collections.Generic;
using System.Linq;
using System.Threading;

namespace test_request
{
    class MainClass
    {
        public static void Main (string[] args)
        {

            string unicode = "Not Your Boyfriend&#39;s Tunic";
            string str = System.Web.HttpUtility.HtmlDecode(unicode);
            Console.WriteLine (str);
        }
    }
}
