Do nothing keyword in C#? [closed]

Answer 1

Why do you want to use a ternary operator, if you only want to do something in one of the cases ? Why don't you just invert the condition and use an if statement ?

if (!officeDict.ContainsKey("0"))
{
    officeDict.Add("0","")
}

Answer 2

Try this (grinns)

    if (officeDict.ContainsKey("0")) 
       Thread.Sleep(1) 
   else
       officeDict.Add("0","")

Answer 3

Setting aside the fact that this is a bad idea, you actually can create a 'DoNothing' method using an attribute to conditionally emit the method call (note this relies on the convention that you don't #define a 'NEVER' condition.) Because of the ConditionalAttribute, calls to the method will not be emitted and you essentially have a 'nop' section of code.

       [Conditional("NEVER")] 
       public void DoNothing() 
       { 
       } 

Still, as several others have already pointed out, this is not recommended.

Answer 4

No, there is no such keyword. Besides, the ?: operator is not meant for deciding actions. It's meant for deciding values (or, more technically, value expressions).

You really, really want to use an if condition for this sort of decision-making instead:

if (!officeDict.ContainsKey("0"))
    officeDict.Add("0", "");
