Yes, In C# 2.0 there is introduced one new type called
nullable types. through this we can assign null value in any
value type like...
bool?flag=null;
but before evaluate this value we should check flag value like..
if(!flag.HasValue)
{
flag=true;
}
after that we have to cast bool value to bool like..
if((bool)flag)
{
//write your code.
}
