BitArray.Not 方法
反转当前 BitArray 中的所有位值，以便将设置为 true 的元素更改为 false；将设置为 false 的元素更改为 true。
**命名空间:**System.Collections
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
Public Function Not As BitArray
用法
Dim instance As BitArray
Dim returnValue As BitArray
returnValue = instance.Not
public BitArray Not ()
public:
BitArray^ Not ()
public BitArray Not ()
public function Not () : BitArray
返回值
具有已反转的位值的当前实例。
备注
此方法的运算复杂度为 O(n)，其中 n 是 Count。
示例
下面的代码示例演示如何将 NOT 应用于 BitArray。
