How to convert UTF-8 to string in C# [duplicate]

How to Decode "=?utf-8?B?...?=" to string in C#

H, I have this string that I got from a htm file
String s = "%u05d9%u05e8%u05d5%u05e9%u05dc%u05d9%u05dd"
It is in UTF8 code value Hebrew characters and I want to convert it to a real string that I can write to a file and have meaning (not just the code value of the char set).
I tried to do this but it does not work -
byte[] bytes = Encoding.UTF8.GetBytes(s);
addr = Encoding.UTF8.GetString(bytes);

The original string might have been UTF-8 encoded, but this is irrelevant because what you have right now is an URL encoded string. You can decode it using HttpUtility.UrlDecode:
System.Web.HttpUtility.UrlDecode("%u05d9%u05e8%u05d5%u05e9%u05dc%u05d9%u05dd")
returns ירושלים

try
System.Net.WebUtility.UrlDecode(s);
