Reflection Methodinfo - how to use remove for a reflected property (List)-CodePudding

My goal is to remove entries from unknown list / collection at compile time.

I'm passing an interface as parameter. With reflection I receive the associated collection and method "Remove".

private void DeleteRowOfUnknownCollection(IMakeClassUsableForStandardGridButton uiModel) {
        Type typView = this.GetType();
        PropertyInfo propInfoCollection = typView.GetProperty(GetCollectionPropertyNameByModel(uiModel));
        object instanceOfCollection = propInfoCollection.GetValue(this);
        Type propTyp = instanceOfCollection.GetType();
        MethodInfo methodRemoveOfCollection = propTyp.GetMethod("Remove");

        object ToBeRemovedUiModel = Activator.CreateInstance(uiModel.GetType());

        methodRemoveOfCollection.Invoke(instanceOfCollection, new [] { ToBeRemovedUiModel } );
    }

Plain and simple - I don't know how to use the Remove method when its reflected and expecting an object intantiated with new.

Any ideas how to remove the passed uiModel?

Thanks in advance!

CodePudding user response：

Thanks to Lasse who pointed to a mistake in code. Passing a new instance of a class instead of the parameter uiModel object.

methodRemoveOfCollection.Invoke(instanceOfCollection, new [] { uiModel } );

Now it works properly!
