How do I write a where statement that will exclude records if both conditions are met.

example:

var filteredRecords=AllRecords.Where(w=>w.Amount!=0 && w.Sales!=0);

so if any record had amount=0 or sales=0 I want to include.
I only want to exclude records where BOTH sales and amount are equal to 0.

 
found a solution

var filteredRecords=AllRecords.Where(w=> !(w.Amount==0 && w.Sales==0));

 
thats the same as writing

AllRecords.Where(w => w.Amount != 0 || w.Sales != 0);

You can distribute the negation, or pull it out.

!(Condition == x || Condition == y). When 'multiplying' the inner conditions by the !, you switch OR to AND or AND to OR, and Equals to Not Equals or Not Equals to Equals.

so... !(Condition == X || Condition ==y) .... Condition != X && Condition != Y is equivalent.
!(Condition != X && Condition == y) is equivalent to Condition == X || Condition != Y

Sound like you just didn't know about the ||, OR, statement, but still useful to know this.
