c# - null / DBNull conversion -

this question has answer here:

• c# ado.net: nulls , dbnull — there more efficient syntax? 6 answers

i have method

void addparam(string name, object value); 

and object

public class foo  {    public string whatever; } 

what best way perform (working) call match logic?

addparam("foo", foo.whatever == null ? dbnull.value : foo.whatever); 

i thinking such thing this:

object getparamvalue(object value) {   if (value == null) return dbnull.value;   return value; }  addparam("foo", getparamvalue(valuefoo.whatever)); 

how can achieve behavior?

you can use null coalesce operation:

addparam("foo", foo.whatever ?? dbnull.value);
