Question

Here is some example code to get started:

class Foo
{
   public bool? IsValid { get; set; }
}

// later in some other function...
void DoStuff( Foo myFoo )
{
   myControlState.Visible = myFoo.IsValid.HasValue ? myFoo.IsValid.Value : false;
}

I run into a lot of situations where I have to use a ternary operator like above to properly use a nullable bool. It would be nice if there was a slightly simpler way of getting the value of the bool without throwing exceptions. The code above seems straight-forward but there are much more complex situations where this ends up being a lot of code. I was hoping for something simple like:

myControlState.Visible = GetNullableValue<bool>( myFoo );

Does anyone have any cleaner alternatives to the ternary operator?

Answer 1

you can use the null-coalescing operator if that makes it more readable.

myControlState.Visible = myFoo.IsValid ?? false;
