Web Method Signature throwing ArgumentException

    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.
