in Classic ASP I was using plus sings and ampersands in a string like this"

arr=arr+myDataReader.item("columnsname")+"?#$"



but ASP.NET is telling me that "Type-declaration character '&' does not 

match declared data type 'System.Array'."



Or



The operands to '+' are of types 'System.Array' and 'System.Object', which 

are not appropriate for this operator



Is there a way to add these things together in ASP.NET?
