c# - Checking multiple session variables if they are null -

i using following check number of session variables:

if(mysession.current.mpr != null && mysession.current.mpr1 != null && mysession.current.mpr2 != null   && mysession.current.mpr3 != null && mysession.current.mip != null && mysession.current.vr != null) {   .... } 

it not work! know 1 of variables not null. suggestions?

your if statement written go inside block if variables not null. go inside if 1 variable not null, use ors || instead of , &&:

if(mysession.current.mpr != null || mysession.current.mpr1 != null || mysession.current.mpr2 != null   || mysession.current.mpr3 != null || mysession.current.mip != null || mysession.current.vr != null) {   .... }
