Any idea how to resolve this problem ? Thanks in advance, Brian 回答1: you cann't use as inside function call, try change your code like this queryable.Where("(PositionID.ToString().Contains(@0))", paramsObj); //PositionID is Int32 UPDATE:

问题 I have run in to a little bit of a problem which is not solved by the generally available solutions to seemingly the same problem. Consider: I have a set of dynamically generated classes, inheriting from a known base Class (lets call it BaseClass ). These dynamically generated classes also have dynamically generated Properties with associated attributes. The attributes are also of a custom class, though not dynamically generated: [AttributeUsage(AttributeTargets.Property)] class TypeAttribute

问题 I'm trying to do the following: public abstract BaseClass { public virtual void ReceiveEvent(Event evt) { ProcessEvent(evt as dynamic); } private void ProcessEvent(object evt) { LogManager.Log(@"Received an event that is not being processed! Dispatch fallback"); } } public DerivedClass: BaseClass { private void ProcessEvent(SpecificEvent evt) { LogManager.Log("Processing Event"); } } SpecificEvents hit the fallback method instead of the one in the derived class. I use dynamic dispatch within
