Question

How can check following code to catch divided by zero error?

active = (g.Sum(x => x.Kullanim_Reaktif) / g.Sum(x => x.kullanim_T0)) * 100

I want something like this:

 if(g.Sum(x => x.kullanim_T0) == 0)
 {
     return 1;
 }
 else
 { 
     return g.Sum(x => x.kullanim_T0);
 }

Can I write if-else in above linq code line (g.Sum(x => x.kullanim_T0))? And how?

Thanks.

Answer 1

active = (g.Sum(x => x.kullanim_T0) == 0 ? 1 : g.Sum(x => x.Kullanim_Reaktif) / g.Sum(x => x.kullanim_T0)) * 100 

but more efficient to do:

var kSum = g.Sum(x => x.kullanim_T0);
active = (kSum  == 0 ? 1 : g.Sum(x => x.Kullanim_Reaktif) / kSum ) * 100
