This exception signals that an error occurred during the handling of a format string. Format strings are used by methods such as Console.WriteLine( ) to replace a format specification with one or more parameters. This exception may be triggered by supplying too few arguments to replace all the format strings (for example, supplying only two arguments to Console.WriteLine( ) when your format string is "{0} {1} {2}"). See Appendix B for more information on format strings.
