You should be comparing to DBNull. Value not null.
You should be comparing to DBNull. Value, not null: TUITIONCurr = g . Where(p =>!object.
Equals(p. Field("TUITION"), DBNull. Value)) .
Average(p => p. Field("TUITION")); Once you've filtered out nulls, you don't need the DefaultIfEmpty() call.
TUITIONCurr = g. Where(p =>!object. Equals(p.
Field("TUITION"), DBNull. Value)).DefaultIfEmpty(). Average(p => p.
Field("TUITION")) returns the same original error – sammarcow Aug 18 '11 at 14:30 In that case, it means one of the p's is actually null; not sure why that would be, but you should assign g.ToList() to a variable and inspect it in the debugger to see what's actually in the sequence. – dlev Aug 18 '11 at 14:47.
Instead of the DataRow. Field method, try using DataRow.IsNull. Also, you don't need the call to DefaultIfEmpty().E.g.
: TUITIONCurr = g . Where(p =>!p. IsNull("TUITION")) .
Average(p => p. Field("TUITION")).
If my answer is technically incorrect, I would like to be made aware. – Donut Aug 18 '11 at 14:37.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
