Can i get a solution for my problem described below ?

I have a stored procedure with a select  query like

Select custcode,mob from tableCustomer where custcode in (@custcode)

here @custcode declared as varchar(50)

from a vb.net page am calling this procedure with parameter strCode with value as
'101','102' but not getting the result 

when directly executing the query with these custcodes in sql am getting the results
