保存并加载数组的初始状态（int [，]）(Save and load initial state of an array (int[,]))

 我正在尝试保存数组的状态，以便稍后在其初始状态下加载它。 但我不知道如何使它们成为单独的实例，而不是相互引用。 以下是一些示例代码： 
 
static void Main(string[] args)
{
    int[,] first = new int[5, 5];
    int[,] second = first;

    for (int i = 0; i < 5; i++)
    {
        for (int j = 0; j < 5; j++)
        {
            first[i, j] = i * j;
        }
    }

    first[0, 0] = 10000;
    first = second;
    Console.WriteLine(first[0, 0]); //10000
}

I'm trying to save the state of an array so I can load it later in it's initial state. But I don't know how to make them separate instances, and not to reference each other. Here's some sample code:
 
static void Main(string[] args)
{
    int[,] first = new int[5, 5];
    int[,] second = first;

    for (int i = 0; i < 5; i++)
    {
        for (int j = 0; j < 5; j++)
        {
            first[i, j] = i * j;
        }
    }

    first[0, 0] = 10000;
    first = second;
    Console.WriteLine(first[0, 0]); //10000
}
