I am using two tables(A&B) to derive the list of items A which are not there in B.
Dim results1 = From table1 In dt2 Where Not (From table2 In dt1 Where DirectCast(table2(0), String) = DirectCast(table1(0), String)).Any() Select DirectCast(table1(0), String)
but i am getting error
Unable to cast object of type 'System.Double' to type 'System.String'.
Where i need to do the conversion?
Don’t use ‘DirectCast’ here – use “table2(0).ToString()” or ‘CType’.
