在C＃中一些集合，如的ArrayList 和的HashTable 有仿制药这是名单，其中; T＆GT; 和词典＆LT; TKEY的，TValue＆GT; 。

In C# some collections such as ArrayList and HashTable have generic alternatives which are List<T> and Dictionary<TKey, TValue>.

阵列是否也有一个通用的替代方案？

推荐答案

如果你正在寻找最相近的数组泛型集合类型，那么你可能需要一个名单，其中，T＆GT; 。但它不是真正的同样的事情。

If you're looking for the generic collection type that most closely resembles an array, then you probably want a List<T>. But it's not really the same thing.

要扩大其他人所说的：有泛型类型的一点是，这样程序员就可以使用的特定类型的的那些泛型类型的实例，根据当前方案的需求。数组是的已的特定类型的。你总是可以只取一 T [] 。

To expand on what others have said: the point of having generic types is so that a programmer can then use type-specific instances of those generic types, based on the needs of the current program. Arrays are already type-specific. You can always just take a T[].

例如，看一下这个简单的函数定义：

For example, look at this simple function definition:

void SomeFunction(int[] x) 

您也可以认为它是这样的：

You could also think of it like this:

void SomeFunction<T>(T[] x) 

，其中程序员只选择了与调用它 INT 的类型参数：

SomeFunction<int>(myIntArray)
