Question

I got this compiler error:

Cannot implicitly convert type ‘bool?’ to ‘bool’. An explicit
conversion exists (are you missing a cast?).

for the following code:

 xEnable = was.xEnable;

xEnable is a nullable column in DB.

Answer 1

This means that

xEnable is of type bool 

and

was.xEnable is of type bool? (ie: nullable bool)

do something like

xEnable = was.xEnable.HasValue ? was.xEnable.Value : false;

where false is the default value in case was.xEnable == null

EDIT
Or if you really want you can user the ?? operator like

xEnable = was.xEnable ?? true;

or

xEnable = was.xEnable ?? false;
