c# - Dynamically returning property values -

i have class like:

class {         public double? londontime { get; set; }         public double? delhitime { get; set; } } 

now, in class, want make these properties dynamic. class b has function foo(classa):

class b  private void foo(class a) double d; {  if(some condition london time)   {     //how pass londontime property     d = returntime();     }  else if(some condition delhi time)  {    //how pass delhitimeproperty     d = returntime();  } }  private double returntime(????) //what should pass here argument {   if(londontimeproperty passed)   {     logic   }   if(delhitimeproperty passed)   {     logic   }     return 0; } 

here, example, if giving me 1 dynamic value, can adjust it.

so, there way pass argument in returntime based on condition , know return ?

some general questions , comments:

why using double instead of datetime?

what mean dynamic?

it seems need this:

double? getlondontime(a a) {     //some logic }  double? getdelhitime(a a) {     //some logic }  void foo(a a) {     if(some condition delhi)         return getdelhitime(a);     if(some condition london)         return getlondontime(a);     return 0; } 

if using datetime, determine if delhi or london time based on timezone.
