title: C# tostring(radix)
body: <p>I have the following line in javascript:</p>
  
  <pre><code>c = Number(string_1.charCodeAt(i) ^ string_2.charCodeAt(u)).toString(16);
  </code></pre>
  
  <p>I need to rewrite it in c#, this is what I got so far:</p>
  
  <pre><code>string c = (Convert.ToChar(string_1[i]) ^ Convert.ToChar(string_2[u])).ToString(16);
  </code></pre>
  
  <p>I'm not able to enter radix value in ToString method. Any suggestions how I can do this? Thanks</p>
