stuck with how to pass a string as seperator in split function.

When this method returns, contains the 32-bit signed integer value equivalent to the number contained in s, if the conversion succeeded, or zero if the conversion failed. The conversion fails if the s parameter is null, is not of the correct format, or represents a number less than MinValue or greater than MaxValue. This parameter is passed uninitialized.
