  string value,
  IFormatProvider provider
)

Parameters

Convert.ToInt32(String, IFormatProvider) has the following parameters.

        provider.NegativeSign = "neg ";
        provider.PositiveSign = "pos ";

        provider.NumberDecimalSeparator = ".";
        provider.NumberGroupSeparator = ",";
        provider.NumberGroupSizes = new int[ ] { 3 };
        provider.NumberNegativePattern = 0;

        Console.WriteLine( Convert.ToInt32( "12345" ));
        Console.WriteLine( Convert.ToInt32( "12345", provider ) );
