I'm trying to you use a web service with my MVC3 controller. This service has an optional parameter, such as

Service.GetObject(int id, DateTime? date)

But when I try to call it will a null value , like

Service.GetObject(12345, null)

I get this error.

Quote

$exception {"Object cannot be cast from DBNull to other types."} System.Exception {System.ServiceModel.FaultException}

Please Help if you can. Thank you!

If it is optional, then just don't include it. That what they show on the MSDN. Amazing what you find out by reading the documentation.

Service.GetOject(12345);

Optional parameters on the MSDN

When I try that
Service.GetObject(12345);
I get a syntax error stating that I'm trying to call with 1 parameter but 2 is expected.

Then we aren't talking about an 'optional parameter' as defined in .NET and how I for one would expect it to be used in C# (where you posted).

I'm afraid you might be forced into reading the documentation for the service and see what the service creator definse as an optional parameter and what their documentation shows as an example of using it.

Since this is all about ASP (unless by MVC3 you mean Marvel v. CapCon 3) this entire thread is probably not in the best place it could be for answers.

Moved to ASP|MVC forum

Are you sure the parameter is optional? Did you write it yourself?
