Web Method Signature throwing ArgumentException

[Gordon]

Hi,

If I create Web Method with input parameter datatypes other than strings
then the Web Method pukes with a "System.ArgumentException Can't convert to
DateTime" when the field is left blank.
e.g public string myWebMethod(DateTime StartDate)

Is there a way to trap and handle this exception. Does this confine
developers to only writing Methods with input parameters as Strings.

Someones experience appreciated

Hi Gordon

You cannot pass null/empty. You can pass DateTime.MinValue to
determine the intention of leaving this field empty.
