Default Output parameter sybase C#


I have a Sybase stored procedure with an output type char parameter (Also it has one Input parameter).

When I try to get the value's parameter I get an NullReferenceException, Object reference not set to an instance.

I debug my web application it shows:

'((Sybase.Data.AseClient.AseParameter)((new System.Collections.ArrayList.ArrayListDebugView(_o Comando.Parameters)).Items[1])).Value' threw an exception of type 'System.NullReferenceException'

My code of this parameters is

AseParameter oParameter = new AseParameter("@outParameter", AseDbType.Char, 10);

oParameter.Direction = ParameterDirection.Output;


What's wrong?

Is Items a method or a property, if the former then you need () not []. Do you need that complex syntax, can't you just read _oComando.Parameters[1].Value?

I suspect the complex syntax is what the debugger is throwing out as ArrayListDebugView is a hidden internal framework class.

Also, you've posted this same topic twice. Please try and avoid that if you expect everyone to work together on an answer.
