title: C#: Parse substring from a string by detecting whitespace
body: <p>If I have various strings that have text followed by whitespace followed by text, how can I parse the substring beginning with the first character in the second block of text?</p>
  
  <p>For example: 
  If I have the string:<br>
      "stringA stringB"   </p>
  
  <p>How can I extract the substring<br>
      "stringB"</p>
  
  <p>The strings are of various lengths but will all be of the format . </p>
  
  <p>I'm sure this can be easily done with regex but I'm having trouble finding the proper syntax for c#.</p>
