In C#, how can I replace\u0026 with &?

Question

I am getting a string in my C# code that comes from some javascript serialization and I see a bunch of strings like this:

  Peanut Butter \u0026 Jelly

I tried doing this:

  string results  = resultFromJsonSerialization();
  results = results.Replace("\u0026", "&");
  return results;

and I am expecting that to change to:

 Peanut Butter & Jelly

but it doesn't seem to do the replace. What is the correct way to do this replacement in C#?

Use another backslash to escape that backslash. "\\u0026" in reality is "\u0026" — Rogue, Jun 24 '15 at 17:56
@RobSchmuecker no offense here, but why didn't you flag this question as duplicate? — , Jun 24 '15 at 18:04
@AndreasNiedermair I'm not au fait enough with C# to make that distinction unfortunately! — Rob Schmuecker, Jun 24 '15 at 18:05

You can use Regex Unescape() method.

  string results  = resultFromJsonSerialization();
  results = System.Text.RegularExpressions.Regex.Unescape(results);
  return results;

You can also utilize the Server utility for HTML encode.

  results = ControllerContext.HttpContext.Server.HtmlDecode(results);
