这实际上与您拥有的解决方案相同,但是我使用了扩展方法.
This is in effect the same solution that you have, but I use an extension method.
public static partial class EnumerableExtensions
{
public static IEnumerable<T> EmptyIfNull<T>(this IEnumerable<T> source)
{
return source ?? Enumerable.Empty<T>();
}
}
这样我们最终得到:
IEnumerable<Thing> procs = APICall(foo, bar);
var result = from proc in procs.EmptyIfNull()
where proc != null
select Transform(proc);
