Formatting Globalized Strings
The String.Format method is quite useful for declaring the text representation of data:
String.Format(“{0}, {1}”, person.LastName, person.FirstName)
However, when globalizing applications, we must use the overloads which accept IFormatProvider:
String.Format(
CultureInfo.CurrentCulture,
“{0}, {1}”,
person.LastName,
person.FirstName)
We can reduce the friction of these calls with extension methods:
“{0}, {1}”.FormatCurrent(person.LastName, person.FirstName)
Each known culture gets its own extension method:
public static string FormatCurrent(this string format, params object[] arguments)
{
return String.Format(CultureInfo.CurrentCulture, format, arguments);
}
public static string FormatInvariant(this string format, params object[] arguments)
{
return String.Format(CultureInfo.InvariantCulture, format, arguments);
}
// Other known cultures
