I have an MVC application and I want to use this ? option.
Please tell me how I can do this. I have written:
int? isfeature;
but, while inserting the value in database, how do I use it?
It is giving following error:
Cannot convert from int? to int .
int? is a shorthand for Nullable<int>, which means that the value can either be an integer or null. To convert a Nullable<int> to an int, use
int? ni = 2;
int i = (int)ni;
or
int? ni = 2;
int i = ni.Value;
This will throw an exception if the value is null, so you can also use
int? ni = null;
int i = ni ?? 0;
to use 0 as a default value.
do you mean something like this?
$foo = $foo == 1 ? $foo : $bar;
Because I don t understand much of your question...
