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

Question

如果查询返回IEnumerable，我怎么能使它平坦，并从数组中的所有T在一个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);
