How to convert bool? to bool in C#?
bool newBool = (x.HasValue) ? x.Value : false;

bool? nullableBool = null;

 bool actualBool = nullableBool.GetValueOrDefault();

if (bn.HasValue)
        {
            b = bn.Value
        }

bool b1;
bool? b2 = ???;
if (b2.HasValue)
   b1 = b2.Value;

bool b3 = (b2 == true); // b2 is true, not false or null

bool? x = ...;
if (x ?? true) {

}

bool converted = (bool)x;

bool? b = ...;

if (b == true) { Debug.WriteLine("true"; }
if (b == false) { Debug.WriteLine("false"; }
if (b != true) { Debug.WriteLine("false or null"; }
if (b != false) { Debug.WriteLine("true or null"; }

bool? b = ...;

if (b == null) { Debug.WriteLine("null"; }
if (b != null) { Debug.WriteLine("true or false"; }
if (b.HasValue) { Debug.WriteLine("true or false"; }
//HasValue and != null will ALWAYS return the same value, so use whatever you like.

bool? b = ...;
bool b2 = b ?? true; // null becomes true
b2 = b ?? false; // null becomes false

bool? b = ...;
if(b == null)
    throw new ArgumentNullException();
else
    SomeFunc(b.Value);

bool? a = null;
bool b = Convert.toBoolean(a);
