Hi,

How can i select multiple columns and calculate the total amount.

For example, in my database i got a few fields which are named:

5hunderedBills, 2hunderedBills, 1hunderedBills, etc.

And the value of those fields are for example:

5, 2, 3

And the sum would be:

5hunderedBills * 5 + 2hunderedBills * 2 + 1hunderedBills * 3

How can i do that with LINQ in one select statement?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
