LINQ IEnumerable<T[]> to IEnumerable<T>

Question

If a query returns IEnumerable, how can I make it flat and have all the T from the arrays in a single IEnumerable?

var types = from genericType in subscriber.GetType().GetInterfaces()
            where genericType.IsGenericType 
            && genericType.GetGenericTypeDefinition() == typeof (ISubscriber<>)
            select genericType.GetGenericArguments();

您可以从Linq使用SelectMany方法：

var flat = types.SelectMany(x => x);
