“关闭”这个词的对立面是什么?

考虑以下(C#)代码。传递给concurvatedrand()的lambda被称为“closed over”名为format的变量。你会用什么术语来描述变量random是如何在MyMethod()中使用的?

void MyMethod
{
    int random;
    string format = "The number {0} inside the lambda scope";

    ConvolutedRand(x =>
    {
        Console.WriteLine(format, x);
        random = x;
    });

    Console.WriteLine("The number is {0} outside the lambda scope", random);
}

void ConvolutedRand(Action<int> action)
{
    int random = new Random.Next();
    action(random);
}
