Lambda for Regex

A few weeks ago I was trying to put together a quick regular expression for converting an entire English sentence into Pascal (or Headed Camel) Case. What would have been rather trivial in Perl was a little ugly in C#.

Tonight, in a typical midnight haze, I realised I could use a lambda expression to tidy it up a bit. Here is the result, short and simple, presented in unit test form:

[TestMethod]
public void ShouldRemoveSpacesAndCapitaliseWords()
{
   const string original = "Should remove spaces and capitalise words";
   const string expected = "ShouldRemoveSpacesAndCapitaliseWords"; 

   Regex rx = new Regex(@"(\s*)\b(\w)");
   string result = rx.Replace(original, m => m.Groups[2].Value.ToUpper()); 

   Assert.AreEqual(expected, result);
}
