Hi,

I want to pass an optional parameter of datetime type to a procedure (in
VB.NET)

But optional parameters require default value.

What value should I use as default for a datetime parameter?

I cannot use "", since it is type string.

Thank you
 
Don't use Optional Parameters would be my advice. Write an overload.
There's a lot of stuff wrong with Optional Parameters....

If you have to use it, come up with some dummy date like 01/01/1900 or some
date that's not valid and use that.

However, I'd really consider writing overloads for it.

HTH,
Bill
 
Ditto on the overloads. If you must, there's also a shared property, DateTime.MinValue, which might be a shade better than making up your own and having to declare the constant. Per the docs: *The value of this constant is equivalent to 00:00:00.0000000, January 1, 0001.* The moral: don't do much math with this one:
