How to Type Cast null as Bool in C#?

Question

I'm having one null-able bool (bool?) variable, it holds a value null. One more variable of type pure bool, I tried to convert the null-able bool to bool. But I faced an error "Nullable object must have a value."

My C# Code is

bool? x = (bool?) null;
bool y = (bool)x;

Answer 1

Use x.GetValueOrDefault() to assign default value (false for System.Boolean) to y in the event that x.HasValue == false.

Alternatively you can use the null-coalescing operator (??), like so:

bool y = x ?? false;
