How to check if a double is null?

I'm querying a database and some of the results I'm getting are null. I'm setting these values to a variable with a datatype of double. Let's call the variable "results". So I tried setting up an if statement to see it equals Null which of course didn't work. Here is the code I have for that if statement:

if (results == null)
{
     results = 0;
}

The error I get with this code is:

The operator == is undefined for the argument type(s) double, null

Is there a better way to determine if it's null?

Solution

  • I would recommend using a Double not a double as your type then you check against null.
