Question

Context
I want to make this call via reflection

instanceOfEventPublisher.Publish<T>(T eventInst);

When I call

`
private void GenCall(IEventPublisher eventPublisher, object theEventObj){

        var thePublisher = eventPublisher.GetType();
        thePublisher.InvokeMember(
            "Publish",
            BindingFlags.Default | BindingFlags.InvokeMethod,
            null,
            eventPublisher,
            new object[] {theEventObj}
            );
    }

`

I get:
System.MissingMethodException: Method ‘EventAggregator.EventPublisher.Publish’ not found.

How to call the generic ?

Answer 1

You might have to do GetMethods() and search for the “Publish” MethodInfo. Or if “Publish” isn’t overloaded you might get away with just GetMethod("Publish"). In either case, you’ll need to call MakeGenericMethod() on the MethodInfo to add your type arguments.

MethodInfo constructedPublish = thePublisher.GetMethod("Publish")
    .MakeGenericMethod( theEventObject.GetType() );
constructedPublish.Invoke( eventPublisher, new object[] { theEventObject } );
