To use like you have to use something like:

SQL

Select * from Prod_Tbl where ProductName like '%TV%' OR ProductName LIKE '%RADIO%';

If you are looking for exact match then the code which you have written will work:

adp = new SqlDataAdapter("Select * from Prod_Tbl where ProductName IN (" + filter + ")", con);

But if the values which you are search are not exact values then you have to use the like operator.

something like

foreach (string name in year)
{    
if (filter.Length > 0)    
{       
 filter += "AND ";    
}    
filter += string.Format("ProductName  LIKE '{0}'", name);}
