title: C# RegEx for decimal number
body: <p>I'm trying to make a Regular expression for a textbox which should only allow either only digits or decimals. For example, I should be able to enter both 10 and 10,350.</p>
  
  <p>The decimal seperator I'll use is "," and the decimal length don't need a limit.</p>
  
  <p>Anyone knows how I can make such a RegEx?</p>
