LINQ sumWhere

[rliq]

Seems I worked it out....

_myArray.Sum(a => a.Equals(n) ? a : 0);

or in my case which has an array of objects with an Int32 Value member.

_myObjectArray.Sum(o => o.Value.Equals(n) ? o.Value : 0);

Is there a neater way?

On another point... does anyone else use the tertiary operator and find that 90% of the time, one of the then/else values is the same as the if value?

Eg (upperbound of a value):

return (a > 25 ? 25 : a);

I always think there should be a binary operator equivelent, so you could remove the ": a" from the end of the above.

Eg:

return (a > 25 ? 25);

should do the same. From my C -> C++ -> C# days, I've always thought this. Maybe my coding style... I don't know...
