Int32.TryParse() returns zero on failure - success or failure?

Question

I read this from msdn about Int32.TryParse()

When this method returns, contains the 32-bit signed integer value equivalent to the num

Answer 1

The Int32.TryParse() method returns a boolean value as return and provides the converted value as an out parameter. So you can check for the return boolean value for the status.

private static void TryToParse(string value)
   {
      int number;
      bool result = Int32.TryParse(value, out number);
      if (result)
      {
         Console.WriteLine("Converted '{0}' to {1}.", value, number);         
      }
      else
      {
         if (value == null) value = ""; 
         Console.WriteLine("Attempted conversion of '{0}' failed.", value);
      }
   }
