A composite format string consists of fixed text intermixed with indexed placeholders, called format items, that correspond to the objects in the list. The formatting operation yields a result string that consists of the original fixed text intermixed with the string representation of the objects in the list. Composite formatting is supported by methods such as String::Format, Console::WriteLine, and StringBuilder::AppendFormat. For more information on composite formatting, see Composite Formatting.
