问题描述
我有一个初始化数组,可能不包含的项目。
I have an initialised array that may contain no items.
让我们把它叫做 A ,
在电话的GetType() A 显然会返回一个类型数组。是否有可能获得该数组包含?
Calling GetType() on a will obviously return a type of Array. Is it possible to get the type of the items the array contains?
显然 A [0] .GetType()将工作,但随后的阵列可以是空的,导致空引用异常。
Obviously a[0].GetType() would work, but then the array could be empty and cause a null reference exception.
推荐答案好了,你可以得到的数组的元素类型:
Well, you can get the element type of the array:
Type type = array.GetType().GetElementType();(这是不太一样获得类型数组中的项目 - 一个 [对象] 可完全处理字符串填充,例如)
(That's not quite the same as getting the types of the items in the array - an object[] may be entirely populated with strings, for example.)
