推荐答案

数组不是为添加或删除元素而设计的。所有方法都改变了数组的大小（ https://msdn.microsoft.com /en-us/library/bb348051(v=vs.110).aspx [ ^ ]）实际上不修改数组对象;他们创建一个新的，用旧数组中的数据填充它并返回一个新的数组对象，而不是与原始数据相同。



对于此类操作，您需要使用集合，最接近数组 System.Collections.Generic.Array<& ft; ：

你总是可以从列表实例： https://msdn.microsoft.com/en-us /library/x303t819(v=vs.110).aspx [ ^ ]。

Arrays are not designed for adding or removing elements. All methods changing the size of array (https://msdn.microsoft.com/en-us/library/bb348051(v=vs.110).aspx[^]) don't actually modify an array object; they create a new, populate it with the data from old array and return a new array object, not referentially identical to the original one.

For such operations, you need to use collections, with the closest to the array being System.Collections.Generic.Array<&ft;:
https://msdn.microsoft.com/en-us/library/6sh2ey19%28v=vs.110%29.aspx[^].

You can always make an array from a list instance: https://msdn.microsoft.com/en-us/library/x303t819(v=vs.110).aspx[^].
