Question

I have a generic method like the one below. And I check that the incomming parameter is a IList but how do I convert the parameter to a IList?

public T myMethod<T>(T parameter)
{
    //check if the parameter is a list
    if (parameter IList && parameter.GetType().IsGenericType)
    {
       //How can I convert my parameter to an IList that supports IEnumerable interface?
       // So i can do the following
       foreach (var listObject in parameter)
       {
           // Do stuff
       }
    }
}

How about (parameter as IList).

I assume you don’t want to just restrict the parameter to an IList in all cases.
