Replace some Characters in a String : <p>I have this String </p>

<pre><code>link="https%3a%2f%2fen.wikipedia.org%2fwiki%2fHuawei/"
</code></pre>

<p>which shoud be like this:</p>

<pre><code>link="https://en.wikipedia.org/wiki/Huawei/"
</code></pre>

<p>I wrote this code:</p>

<pre><code>link.Replace("%2f", "/");
link.Replace("%3a", ":");
</code></pre>

<p>But it did not work.</p>
