void SomeFunction(DateTime date)
{
string text = date.ToString(); //This crashes if date is null
}
I am using a construct similar to above. I want to check if the date is null

I want to set a DateTime field to Null before passing it to the DB
//First I check to see if anything is in this datarow column, because
sometimes we have no data.
DateTime dt;

{
//We assume the data is a date
dt = (DateTime)datarow;

I have a generic function that receives a couple of datetime values to
work with. They can or cannot have a value, therefore I wanted to use
null. This function will call a database stored procedure and must save
either a null or a real date.
However, passing a hardcoded "null" to call this function causes a
compilation error :
cx.cs(136): Argument '16': cannot convert from '<null>' to
'System.DateTime'
