# How can I set contents of a spreadsheet cell to Accounting format with EPPlus?

I need to set the contents of certain columns to Accounting format. This attempt: public static readonly string NUMBER_FORMAT_ACCOUNTING = "$"; . . . bidPriceCell.Style.Numberformat.Format = NUMBER_FORMAT_ACCOUNTING; ...simply gives "$" and "-$" as the values. This attempt: public static readonly string NUMBER_FORMAT_ACCOUNTING = "$0.00"; . . . bidPriceCell.Style.Numberformat.Format = NUMBER_FORMAT_ACCOUNTING; ...gives me values such as, "$24.09" and "-$0.91" What the user wants is space between the dollar sign and the value, and parens around negative values, such as "$24.09" and "$ (0.91)" What string do I need to assign the Numberformat.Format property for this to work?
