How to determine if a bool variable has not been assigned a value?

andrew22y ago

If you need bool with no-value you can create enum: public enum MyBool { NoValue, True, False } then: MyBool val; and to test: if (val == MyBool.NoValue) of course you can't do: MyBool val; if (val == MyBool.NoValue) because you need to initialize the value and the compiler will complain. If you have MyBool inside of class, the compiler will initialize it to NoValue.

bool is a value type variable there for it cannot be null, so its either true or false

Also remember that a bool var is assigned false by default, during compilation. Thats if you didn't initialize it to anything.

First Initialized the value of test (test = true, false not null) in your situation the value of test is consider as a False not null.
