This enumeration specifies a number of style rules that may be used when a numeric type uses the Parse( ) method to convert a string into a number.

public enum NumberStyles {
   None = 0x00000000,
   AllowLeadingWhite = 0x00000001,
   AllowTrailingWhite = 0x00000002,
   AllowLeadingSign = 0x00000004,
   Integer = 0x00000007,
   AllowTrailingSign = 0x00000008,
   AllowParentheses = 0x00000010,
   AllowDecimalPoint = 0x00000020,
   AllowThousands = 0x00000040,
   Number = 0x0000006F,
   AllowExponent = 0x00000080,
