As Peter said the actual db addition of a null would be System.DbNull.
But i am guessing you want to also know how to make your method allow null
parameter values?
if so its like this
public void InsertRow(char gender, double? decimalAge, double? height,
double? weight)
{
//Adds data into a MySQL database
}
the ? after double, double? or with an int, int? just means it can have a
null value. When inserting that null into db use the System.DbNull.

Say for example i have a hypothetical function taking 4 parameters such as
the one below:

}

If i have a piece of data missing such as height, but i still want to call
the function that will add the other parameters into the database, how
would i do it? I'd like to pass
a 'null' to the function, is there any way of achieving this without
getting compiler errors?
