if statement - c# If Control in single row -

i using asp.net mvc view , in order utilize if command .

my code:

<div class="panel-body @(((objectmodellibrary.law)viewdata["currentlaw"]).laststatus == "" ? "collapse" : string.empty)">

my question above if control:

i want check

if ((objectmodellibrary.law)viewdata["currentlaw"]).laststatus == null || if ((objectmodellibrary.law)viewdata["currentlaw"]).laststatus == ""

i want utilize ? "collapse" : else : string.empty)">

how can utilize if not null , if not "" in 1 row in code?

if you're checking whether string value either null or "" utilize isnullorempty:

string.isnullorempty(((objectmodellibrary.law)viewdata["currentlaw"]).laststatus) ? "collapse" : string.empty

if want combine multiple conditions in conditional expression, can logical operators. example:

if (somecondition && someothercondition)

this require both conditions true. (if utilize || operator instead require at to the lowest degree one status true.)

so in ?: operator might like:

(somecondition || someothercondition) ? somevalue : someothervalue

logical segments of conditional expressions can grouped parentheses, can include many like:

(condition1 || (condition2 && condition3)) ? somevalue : someothervalue

technically can build conditions , other expressions big you'd like, though of course of study code readability , maintainability becomes issue pretty quickly. extracting logic separate methods helps maintain code more organized.
