As I see it, you have two options:
1) Declare a value-type wrapper for each of the types that have
different system-wide formatting requirements and override the
ToString() method to "do the right thing every time". You can create
implicit conversions to and from the underlying native type so that
they can be freely passed around.
2) Declare a mapping of types to IFormatProviders (a Dictionary<Type,
IFormatProvider>) and initialize that at startup. Then EVERYWHERE you
want the value formatted, you can call a helper method that takes the
raw value and looks up the IFormatProvider to pass down to the native
ToString() methods. In GMail tested code:
public static Dictionary<Type, IFormatProvider> s_Providers = /// init this up
public static string MyFormattedToString<T>(T value)
{
IFormatProvider formatter = s_Providers[typeof(T)];
// no formatter registered, punt to general ToString();
if (formatter == null)
return value.ToString();
// use the formatter as desired... and return
return value.ToString(formatter);
}
