Hello,

I'm a .NET newbie but have 12 years of C++/MFC.

In C++, atoi() stops converting at the first non-digit, so in this code,
octet will be 192:

   int octet = atoi("192.");    // <-- note '.' at end of this string

This is great, exactly what I want.  But to achieve it in C++/CLI, the code
I am using is this:

  try
  {
      int octet = Convert::ToInt16("192.");
  }
  catch (Exception^ )
  {
      // Convert::ToInt16 throws when there are non-digits in parameter
  }

Because an exception is thrown, the conversion is not successful.  This is
highly unusable!  I've had to strip off the '.' so Convert::ToInt16() is
successful in the normal case.

However, if the string is malformed (doesn't contain any digits), the
exception is still thrown, whereas atoi() simply returns a value which I
skip.  Maybe I'm misunderstanding exceptions (I don't use them even in C++
when I can help it), but having to try/catch an exception instead of just
getting a simple return value seems to be adding complexity instead of
reducing it.  I don't like replacing 1 line of C++ with 8 lines of .NET for
a simple conversion.

Is there a better way?
